 AN OLD BUT FORMIDABLE WEAPON
The gambit... The history and origin of the word is quite in-
volved.
The earliest application of the word to chess playing was
ostensibly made in Spain: the term "gambit" was brought into
chess vocabulary by Ruy Lopez (Libro del juego del ajedrez,
1561) who applied it to the Damiano Gambit in the form gambi-
to. The Italians seem at first to have readapted the word as gam-
bitto (G. Polerio in MS, 1575, who opposes giuochi piani to gi-
uochi gambitti)\ later they employed the native form gambetto,
from which the earliest English form "gambet(t)", and later the
English "gambit" come.
The word itself is derived from the Italian word gamba,
meaning "a leg"; and gambitare, meaning "to set traps". Italian
wrestlers speak of gambitare, by which they mean "to set traps to
catch the legs".
The gambit, a cunning and sharp method of opening a game,
does, indeed, conceal a lot of dangerous traps and snares.
In offering a gambit one of the sides (more often White) sac-
rifices a Pawn or two, although occasionally a piece may be in-
volved, to gain time or space, to break up the opponent's centre,
or to set the stage for an early and more effective attack against
the enemy King.
If, in reply to a gambit offered by White, Black also resorts
to a sacrifice, striving to achieve the same objects as his opponent
does, then this method of fighting is called a counter-gambit; if,
however, a sacrifice is turned down by Black, we speak about a
declined gambit.
 Gambits, the old openings, have been known for more than
four centuries. In the mid-16th century when the latest improve-
ment, castling, was introduced, the long evolution of the old sha-
tranj* came to an end.
The game became more profound, dynamic and fast-
moving. The golden age of chess, a natural consequence of the
progress along the literary, artistic and cultural lines of the Re-
naissance, had come.
But what were the rules of the medieval shatranj? How did
they differ from those of modern chess?
As regards individual pieces, the Rook, Knight and King
seem to have had the same move as at present. The Pawn for-
merly could move only one square ahead. It was customary for it,
on arriving at the eighth (first) rank, to be exchanged only for a
Queen and no other piece. The Queen formerly njoved one
square diagonally and was consequently a weak piece. The
Bishop could move only two squares in a diagonal and had no
power over the intermediate square, which could leap over
whether it was occupied or not.
Not only mate but also stalemate were then considered to be
a win. One could also win by capturing all enemy pieces and
Pawns (but not a King).
The powers of the chessmen, increased about the early part
of the 16th century, have called for a fresh evaluation of the im-
portance of any single move. It also made the King's position, as
well as the squares f2 and f7, defended by the King alone at the
beginning of a game, more vulnerable.
The desire of making a successful attack on the enemy mon-
arch's citadel very early in a game has given rise to a gambit.
Gdttingen Manuscript (circa 1485, in Latin) is believed to
have been the first publication of the "new chess era", and it
came to be accepted as the earliest record of modern gambit

Shatranj is a foreign word among the Persians and Arabians, whereas

its natural derivation from the term chaturanga is obvious: chess in its ori-
gin in India was a four-sided game; its name chaturanga or shatranj is de-
rived from the Indian word for "four".

chess play. This chess publication contains 12 openings. The first
opening is of interest, because it will give the reader an idea of
what a gambit is.
1. e4 e5 2. Nf3 f6 3. Nxe5 fe 4. Qh5+ Ke7 5. Qxe5+ Kf7 6.
Bc4+ d5 7. Bxd5+ Kg6 8. Qg3+ Qg5 9. Qb3 Qxg2 10. e5 (1).
No assessment of the resulting position is given.
The Knight's sacrifice on e5 (an opening innovation at that
time) is also mentioned in the book of the first true chess theory
by the Spanish master Juan Ramirez Lucena, which appeared in
1497.
The Knight's sacrifice on e5 was invented by Damiano, a
16th-century apothecary of Odemira in southern Portugal. In
1512 he published his Libro da Imparare Giocare a Scacchi in
which, among other things, he pointed out the best continuation
for White after 3. Nxe5; instead of the impulsive check on g3
(8. Qg3+), he recommended an excellent alternative — 8. h4!,
regarded up to now as White's best move (2).
As is known, after this thrust of the White Rook's Pawn,
Black finds himself in a critical situation. Damiano's book was
translated into English and was published in London in 1562. In
opening theory the Knight sacrifice on e5 has been known as the
Damiano Gambit.

 The echoes of an ancient shatranj resound in the Damiano
Gambit, while the romantic King's Gambit on the basis of the
new rules of the game necessitated its novel strategy and tactics.
The King's Gambit was first mentioned by Ruy Lopez de Segura,
a clergyman of Zafra in Estramadura, Spain, one of the strongest
and most influential 16th-century chess players, in his book Libro
de la invention liberal y arte del juego del ajedrez (Book of the
Liberal Invention and Art of Playing Chess), published in Alcala,
Spain, 1561.
In the late 16th and early 17th centuries a new Italian school
of chess appeared, which advocated an immediate attack on the
opponent's King, regardless of losses. The Italian school con-
ceived original combinations and developed the aesthetics of
chess. Its most famous players were G. Leonardo, A. Salvio and
G. Greco, whose work was regarded for almost a century as the
best guide to chess. G. Polerio has contributed greatly to opening
theory, especially the King's Gambit. During the matches, Pole-
rio wrote down the games; thus he became one of the first known
"seconds" and a forerunner of chess tournament reporters. G.
Polerio was the best analyst of the King's Gambit of his time.
Here is one of the examples Polerio gives:
1. e4 e5 2. f4 ef 3. Nf3 g5 4. Bc4 g4 5. Ne5 Nh6 6. Nxg4 Nxg4
7. Qxg4 d5 8. Qxf4 dc 9. Qe5+ Be6 (3) 10. Qxh8 Qh4+ 11. Kfl
Qf4+ 12. Kgl Qxe4 13. h3 Bd5, with the decisive advantage for
Black.
Polerio called this continuation "the most beautiful defence
against the Gambit".
For several centuries the King's Gambit has occupied a
worthy place in both chess theory and practice. In the 19th cen-
tury new gambits were invented. Many celebrated masters of the
game, "kings of chess"—Charles La Bourdonnais, Alexander
MacDonnell, Adolf Anderssen, Paul Morphy, Johannes Zuker-
tort, Wilhelm Steinitz, and Mikhail Tchigorin, turned gambits
into a formidable weapon.
"That is all very well, but it's all in the past," we remark
sceptically, "gambits are no longer played..."
Indeed, formerly the so popular King's Gambit and other
gambit systems can rarely be met today in top-level tournaments
and matches.
 Why?
The explanation lies in the development of the principles and
methods of positional play, and the greatly improved defensive
technique.
But it is a naive misconception to think that gambits have be-
come obsolete, that they are "a weapon of the Stone Age". Com-
bining the features of an art, a science, and a sport, any game
helps develop logic, concentration, and the ability to calculate
possible sequences of moves quickly and accurately, and gam-
bits—especially.
"Gambits lead to refined attacks. The King's Gambit, one of
the most impressive elements of the theory, is the main represen-
tative of this family," wrote Mikhail Tchigorin.
Karl Jaenisch, who made a considerable contribution to the
emergence of the Russian Chess School, styled the King's Gam-
bit as "an imperishable monument of human wisdom".
The main idea behind all gambits is contained in the follow-
ing explanation: in offering a gambit a player takes a great
number of risks. He sacrifices material to gain time or space, or
for some other advantage. It is an excellent coordination of the
player's combat pieces which enables him to win by his skill
rather than by "greater numbers".

 The modern theory has, to a certain extent, solved the prob-
lem of rendering gambit attacks of the old, tested openings harm-
less. But the ideas of the attacks, being logical and sound, regen-
erate on new soil. Just think of the number of currently used
opening systems, the fascinating lines that have recently been dis-
covered in the Sicilian and Caro-Kann defences and in various In-
dian build-ups! New gambits have also appeared, like the Volga
and Benko gambits.
Rejecting rigidity of the gambits with their motto "I declare
war on you", modern theorists search for lines in gambit schemes
that make positional manoeuvring possible. Adopting these sys-
tems, they plan to obtain some facilities in the endgame.
Lasker wrote, "gambit ideas are fruitful in discovery of new
possibilities. A gambit is a powerful weapon, especially when
used against opponents burdened with bookish knowledge".
Yes, the gambit is an old but formidable weapon, and one
should learn how to handle it!
The current World Champion Garri Kasparov is a recog-
nized master of gambit play. One of his main methods of strategic
and tactical fights is a Pawn sacrifice. This brilliant manner of
playing has gained Kasparov many convincing wins, and has
made his creative attitude towards the game very popular among
a wide circle of lovers of chess.
To close the chapter let us examine three examples of the
gambit play taken from modern tournament practice.
Pirc—Ufimtsev Defence
Tal Tringov
Amsterdam, 1964
1. e4 g6 2. d4 Bg7 3. Nc3 d6 4. Nf3 c6 5. Bg5 Qb6.
Premature attack. He should have continued developing his
pieces—5. ... Nf6.
6. Qd2!
Pawn sacrifice to gain the lead in development.
6. ... Qxb2.
A risky move, but at least consistent with his preceding
move, which would otherwise be quite aimless.
9
 7. Rbl Qa3 8. Bc4 Qa5.
On 8. ... b5? White would answer 9. Nxb5 cb 10. Bd5.
9. 0—0 e6.
The developing 9. ... Nd7 would have been better than the
text-move.
10. Rfel a6.
Black obviously senses no danger. He should hiive with-
drawn his Queen to c7 without losing a tempo to make the pre-
ventive move in the game.
11. Bf4 e5.
Here, again, the retreat 11. ... Qc7 would offer much stiffer
resistance, although after 12. e5! White would have a potent at-
tack, nevertheless. On 12. ... d5, he may proceed with 13. Bxd5!
12. de de 13. Qd6! (4)
Played in the best traditions of the old gambits! Black has
now to choose between capturing the Bishop or the Knight,
neither alternative being satisfactory.
13. ... Qxc3.
Equally hopeless would be 13. ...ef 14. Nd5! Nd7 (14. ...cd
15. e d + , etc.) 15. Ng5 Be5 16. Nc7+ Qxc7 17. Bxf7+ Kd8 18.
Ne6 mate!
14. Redl Nd7.
On 14. ... Bd7 15. Rxb7 would decide the issue.

No. 4 No. 5
 15. Bxf7+Kxf7 16. Ng5+ Ke8 17. Qe6+. Black resigns.
After 17. ... Kd8 the Black King would be dethroned in no time:
18. Nf7+ Kc7 19. Qd6 mate.
Queen's Gambit Accepted
Taimanov Polugayevsky
Leningrad, I960
1. d4 d5 2. c4 dc 3. ND Nf6 4. Qa4+ Nbd7 5. Nc3 e6.
Here theorists prefer to transpose into one of the variations
of the Griinfeld Defence by playing ... c7—c6 and then fianchet-
toing the dark—squared Bishop (... g7—g6 and Bf8—g7).
6. e4 c5 7. d5 ed 8. e5!
Here it is, a modern gambit! Black's best choice now is 8.
...b5!, giving his extra Pawn back and allowing him to meet 9.
Nxb5 by 9. ... Ne4, while 9. Qxb5 may be countered with 9. ...
Rb8, bringing his Q-side pieces into play.
8. ... d4 9. ef dc 10. Bxc4 Qxf6 11. Bg5 Qc6 (5)
12. 0—0—0!
Following up in fine gambit style. Should Black accept the
offer of the Queen, he would lose by force: 12. ...Qxa4 13.
R h e l + Be7 14. Rxe7+ Kf8 15. Rxf7+ Kg8 16. Rfxd7+ Qxc4 17.
Rd8+ Kf7 18. Ne5+, winning the Queen back and remaining a
piece ahead.
12. ... cb+ 13. Kxb2. Also good is 13. Kbl.
13. ... Be7 14. Rhel f6 15. Bb5 Qb6 16. Kcl fg 17. Bxd7+ Kf8
18. Rxe7! Kxe7 19. Qe4+ Kd8 20. Bf5+ Kc7 21. Qe5+ Kc6 22.
Rd6+ Kb5 23. Qb2+. Black resigns.
The romantics of the past would doubtless have been fasci-
nated by this brilliant game!
Queen's Indian Defence
Kasparov Gheorghiu
Moscow, 19X2
1. d4 Nf6 2. c4 e6 3. ND b6 4. a3.
This continuation was introduced into modern practice by
Tigran Petrosyan. The plan behind it is to secure the position of
the Knight on c3, by preventing the Black Bishop from develop-
ing to b4, where it would pin the Knight.
4.... Bb7 5. Nc3 d5 6. cd Nxd5 7. Qc2 c5 8. e4 N\c3 9. be Be7.
A natural but inexact reply. He should have preferred 9. ...
Nc6 or 9. ...Nd7.
10. Bb5+ Bc6 11. Bd3 Nd7 12. 0—0 h6?
This is nothing but a loss of time. He should instead have
played 12. ...0—0 without fearing the variation 13. d5 ed 14. ed
Bxd5 15. Bxh7+ Kh8 16. Be4, and Black's position is tenable.
13. Rdl! Qc7.
At this moment, castling K-side would be weaker than on
the previous move, for instance, 14. d5 ed 15. ed and if 15. ...
Bb7, then 16. c4, with a clear advantage to White.
14. d5!
Black is late to castle and, sacrificing a Pawn, White opens
up the game and launches a bold assault on his Black Majesty's
residence.
14. ... ed 15. ed Bxd5 16. Bb5(6)
For the Pawn he has sacrificed, White now has a powerful at-
tack. The attempt to disentangle the Black pieces by 16. ... Bc6
would be strongly met by 17. Bf4 Qb7 18. Bxc6 Qxc6 19. R e l ,

No. 6 No. 7

12
then it would be even harder for him to coordinate his forces.
And 16. ... Be6 would be equally unconsoling because of 17.
Qe4!
16. ... a6 17. Bf4!
Avoiding the trap 17. Bxd7+ Qxd7 18. c4 Be4! and all is well
with Black.
17. ... Qxf4.
At this stage, however, 17. ... Qb7 18. Bxd7+ Qxd7 19.c4
would be bad for Black, in view of 19. ... Qg4 20. Rxd5 Qxf4 21.
Rel, etc.
18. Bxd7+ Kxd7 19. Rxd5+ Kc7.
After 19. ... Kc8 he could put up a stouter resistance.
20. Rel! Bd6.
In the event of 20. ... Bf6 21. Re4, Black would lose his
Queen.
21. Rf5 Qc4 22. Re4!
Not, of course, 22. Nd2?, because of the unpleasant surprise

22. ... Qb5 23. Rxf7+ Kb8 24. Re6 Rd8 25. c4 Qc6 26. Ne5
Qc8 27. Qbl!
Black resigns, as 27. ... b5 is simply refuted by 28. cb.
A triumph of modern gambit play!
Yes, modern. And anyone would be quite justified in assert-
ing that even now in almost any opening there are unearthed
gambit ideas, and their quest offers excellent opportunities for
lovers of chess, for independent creativeness and perfection of
the game.
When 1 was a young chess player, I had gambit lines of my
own in almost every opening I used to adopt; and I can assure you
that these findings of mine put my opponents in a spot quite
often. Here is one of my prepared lines in the once popular vari-
ation of Alekhine's Defence.
1. e4 Nf6 2. e5 Nd5 3. d4 d6 4. c4 Nb6 5. f4 de 6. fe Nc6 7.
B e 3 Bf5 8. Nc3 e6 9. Nf3 Be7 10. Be2 Qd7 11. 0—0
o - o - o (7)
At this point I used to play 12. Rel!? and, should my oppo-
nent reply by 12. ... f6, I would start up "the infernal machine"
of my gambit: 13. d5 Nxe5 14. Nxe5 fe 15. c5 Nxd5 16. c6! Qxc6
17. Nb5!
13
 I do not intend discussing the positive and negative aspects
of the move 12. Rcl!? In any case, it leads to a complicated game.
In this book the reader will find facts about many gambits,
their past, present and even future.
And now for the gambit!
 THE IMMORTAL GAMBIT
That is what the King's Gambit can rightfully be called.
1. e4 e5 2. f4 ef (8)
The idea behind the Pawn sacrifice is that White will now be
able to play d2—d4, gaining control of the centre and opening the
King's Bishop file for his Rook. After castling (usually K-side)
and eliminating the Black Pawn from its post on f4 White will
open the f-file and will obtain real prospects of attacking the
enemy King's shelter at the point f7. The early advance of the
King's Bishop Pawn is questionable —2. f4. Black gains material
superiority for a while, White King's shelter is weakened, Black

No. 8
threatens to check with his Queen at h4—complications come
thick and fast in this opening.
As you already know, the King's Gambit has been used for
four centuries. It goes without saying that over this long period of
time an enormous amount of practical material has been accumu-
lated, papers, analyses and monographs have been published; but
I would venture to say that this gem of opening theory ought to
be part of the repertoire of every chess player.
In this book, we shall first examine the old methods of attack
and defence in the gambit and then we shall pass on to the mod-
ern systems of defence, which render gambit less dangerous to
some extent.
THE KING'S KNIGHT'S GAMBIT
1. e4 e5 2. f4 ef 3. Nf3 g5
For over three centuries the defence of the Pawn on f4, the
creation of the threat of g5—g4, has been regarded as the best
continuation (9).
The plans of play that White has at his disposal can condi-
tionally be divided into two groups: (1) ignoring the threat of

No. 9

16
g5—g4, White continues developing his pieces; (2) White
launches K-side operations, forcing the advance g5—g4.
We note that Black's plan to change the course of the game,
playing 3. ... f5!?, is rather dubious and hardly to be recom-
mended. There may follow, for example, 4. e5 (the sequence 4.
ef d5 5. d4 Bd6 is less convincing) 4. ... d5 5. d4 g5 6. h4 g4 7. Ngl
f3 (7. ... Be7 8. Bxf4 Bxh4+ 9. g3 is favorable for White) 8. Bg5
fg 9. Bxg2 Be7 10. Nc3 Be6 (10. ... Bxg5 11. hg Qxg5 12. Nxd5
Na6 13. Ne2 c6 14. Ndf4 h5 15. d5! it is not good, and the other
side will find it difficult to repulse White's attack) 11. Nge2 Qd7
12. Nf4, and Black is in trouble.
THE MUZIO GAMBIT
1. e4 e5 2. f4 ef 3. Nf3 g5 4. Bc4 ...
The alternative 4. Nc3 has also been tried, with a possible
continuation 4. ... g4 5. Ne5 Qh4+ 6. g3 fg 7. Qxg4 Qxg4 (10).
Weaker is 7. ... g2+ 8. Qxh4 ghQ 9. Qh5 Nh6 10. d4 d6 11.
Bxd6 de 12. 0—0—0 Bxh6+ 13. Oxh6 Qf3 14. Nd5 Bg4 15.
Bb5+ c6 16. Rfl and White has a vicious attack (G. Leven-
fish). The line 8. Nxg4 d5 9. Bh3! de 10. Nf6+ Kd8 11.
Bxc8 Kxc8 12. Ncxe4 gh 13. Rxh2 (11) gives White an active

17
game for the Pawn he has sacrificed, but hardly anything tangi-
ble. This is the Knaade Gambit, named after a little-known
theorist.
The gambit proposed by the Russian chess player A. Rosen-
troeter in the first half of the 19th century is hardly more promis-
ing for White, either: 4. d4 g4 5. Ne5 Qh4+ 6. g3 fg 7. Qxg4
Qxg4. Here, too, the greedy 7. ... g2+ is fraught with unpleasant
consequences after 8. Qxh4 ghQ 9. Nc3 (not, of course, 9. Qh5
Qxe4+ 10. Be2Be7 11. Qxf7+ Kd8 12. Bg5 c6! 13. Qf8+ Kc7 14.
Bxe7 Nxe7 15. Qxh8 Qh4+.—Rosentroeter) 9. ... d6 10. Nxf7!
and should Black reply 10. ... Kxf7 he is hardly to be envied after
11. Qh5+ Kg7 12. Kf2! Yet, the restrained7. ... Qxg4 8. Nxg4 d5
gives him sufficient counterplay (12). But let us return to the
main line. After 4. Bc4 g4 White may suddenly castle, offering his
Knight—5. 0—0 (13).
This bold Knight sacrifice is mentioned in Polerio's MS. But
to everyone's astonishment the attack was named after the little-
known Italian chess player D. Muzio. Such are the caprices of
chess theory, which the famous S. Tartakower, a man of wit. re-
ferred to as "an old weak-sighted lady".
The Knight sacrifice is quite correct, and Black can only suc-
ceed in keeping the game balanced with very precise play. We
should also note that 5. Ne5 (instead of castling) is weak, for after

dangerous attack, for example, 8. Q e l g3 9. Nxh8 Bf2 10. Qdl
Nf6 11. d4 d5 12. ed Bg4 13. Be2 Nxd4 and though White is a
Rook ahead, his position is pitiful (14).
We draw the reader's attention to the fact that in the old
lines of the King's Gambit, on its first moves, the two Kings
(White and Black) became objects of hand-to-hand clashes.
5. ... gf 6. Qxf3 Qf6
After long searches and experiments, after brilliant dis-
coveries and bitter failures the theorists have finally come to the
conclusion that Black's last move is the best one.
Tchigorin also played here 6. ... Qe7, which leads to as great
complications as the text-move does. White can now methodi-
cally prepare the offensive by 7. d3, followed by Nc3 and Bxf4;
but 7. Qxf4, recommended by Keres, is also very interesting.
After 7. ... Qc5+ 8. d4 Qxd4+ 9. Be3 Qxc4 10. Qe5+ Qe6

(15).

 According to V. Panov, this is "a typical gambit sacrifice
without any obvious tactical purpose, serving to open an impor-
tant central file". The continuation 7. d3 Bh6 8. Nc3 Ne7 has also
been tested, only to find that it ultimately leads to Black's advan-
tage.
7. ... Qxe5
8. d3 ...
One will receive a good idea of the astonishing possibilities
concealed in this "devilish", to use Tartakower's definition, gam-
bit by examining the following two variations:
(a) 8. Bxf7+!? Kxf7 9. d4 Qxd4+ 10. Be3 Qf6 11. Bxf4 Bg7
(11. ... Ne7 also deserves consideration) 12. Nc3 Ne7 13. Nd5
Nxd5 14. Qxd5+ Qe6 15. Bd2+ Kg8 16. Rael and Black is lost,
for example, after 16. ... Qxd5 17. Re8+ Bf8 18. Bh6, etc., as oc-
curred in the Smirnov—Tikhonov game (1954), which gives much
food for analytic thought (16).
(b) 8. b3?! (17) The idea behind the bizarre Rook sacrifice is
to cut off the Black Queen from the K-side and to bring crushing
forces on the Black King (via the point f7). But already in the
mid-19th century it became clear that, having accepted the offer,
Black could easily defend himself: 8. ... Qxal 9. Nc3 Bc5+ 10.
Khl Ne7 and now 11. d4 would be met by 11. ... Bxd4 12. Qxf4
Qxcl!, and White's dashing assault would come to nought. On

No. 16 No. 17

20
12. Bxf7+ (instead of 12. Qxf4) Black also has a reliable de-
fence— 12. ... Kd8 13. Bd2 Q x f l + 14. Qxfl Rf8, where the ad-
vantage is certainly his.
8. ...Bh6
9. Nc3 Ne7
10. Bd2 Nbc6
11. Rael Qf5
In this gambit variation each move (both White's and
Black's) has been thoroughly analyzed. Yet, it does not mean
that absolutely everything is known here, and that there is noth-
ing to be discovered. On the contrary, there are still consider-
able possibilities for fresh search and experiment. Thus, instead
of the retreat of the Black Queen to f5, some theorists again have
started analyzing the old alternative 11. ... Qc5+. For example,

The crucial position of the variation, also important for the
evaluation of the whole gambit, has been reached. The natural-
looking 13. Bc3 is hardly sufficient. For example, 13. ... Re8 (to
13. ... Rf8 White can strongly reply 14. g4 Qg6 15. h4 bringing all
his reserves into play) 14. Bf6 (or 14. Nf6 Rf8 15. g4 Qg6 16. h4

able for White would be 15. Bxg5 Qxg5 16. Nxf4 d6 17. Bxf7, in

Qxf4 d6 19. Nf6 Rf8 20. Re2 Bf5! (20). After this powerful rejoin-
der, found by the Soviet master A. Rabinovich, White's attack
comes to a standstill.
13. Qe2 ...
This strong move was introduced by the American amateur
player McLean. The idea intrigued Mikhail Tchigorin, a great ex-
pert of gambit play, and the then Russian Champion subjected
the line to a close analysis. The McLean attack was later de-
scribed in a special monograph, published by the Russian chess
player Eugene Znosko-Borovsky (Leipzig, 1910).
It is now unsatisfactory for Black to play 13. ...Nxd5 14.
Bxd5 Qxd5, in view of 15. Bc3 Qc5+ 16. Khl Bg5 17. Bxh8 Qf8

also dubious. For example, 14. Nxe7 Qc5+ 15. Rf2 Qxe7 16. Qh5
Qg5 17. Qxf7 Qg6 (if 17. ... Rf8, then 18. Bxf4) 18. Bc3! Rf8 19.

This repetition of moves is forced. It is the logical, though
unexpected, outcome of the previous play, in which everything
seemed to hang by a thread. As Znosko-Borovsky pointed out in
his monograph, 16. ...Qg4 would be unfavorable to Black be-
cause of 17. h3 and now 17. ... Qg6 would be met by 18. Bxf4
with a fierce attack.
Needless to say, instead of the too committing advance g5—
g4, Black may proceed in a quieter manner
4. ...Bg7 (23)
The reader sees before him a position resulting from the ini-
tial moves of the Greco-Philidor Gambit. The abundance of all
these "subdivisions" of the King's Gambit, named after celebrat-
ed masters of the game and after little-known amateur players
alike, should not be a surprise for him as it has already been men-

tioned above that the King's Gambit has for centuries remained
the most popular opening, and the analyses and developments of
its various systems by theorists of all ranks have served as
Ariadne's thread in the labyrinth of its innumerable variations.
5. 0—0 ...
This method of attacking was Tchigorin's favorite, wheras
the greatest 18th-century French chess player Francois Philidor
recommended 5. h4. For a long time Philidor's continuation was
regarded as an almost "must"; but with accumulated knowledge
it became obvious that by playing in this manner White can gain
very little. Here are several exemplary variations:
(a) 5. ... h6 6. d4 d6 (here, too, in the case of 6. ... g4, White
can sacrifice the Knight, which would give him—7. Bxf4 gf 8.
Qxf3—a powerful attack) 7. c3 (again, Philidor's suggestion) 7.
... Nc6 (24).
At this point, White has a good answer to 7. ... g4 at his dis-
posal viz., 8. Ngl. Keres gives here 8. ... Qe7 9. Bxf4 Qxe4+ 10.
Qe2 Bf5 11. Nd2! with a very active game for White, which more
than compensates him for the Pawn he gave up. But the offer of
the Knight by 8. Bxf4, instead of 8. Ngl, also deserves serious
consideration.

an attack against the point f7) 8. ... Qe7 9. 0—0 Nf6 (tempting is

Nxd4! But Black should not forget that he is behind in develop-
ment. After 10. Nh2! f3 White can answer by the strong 11. Nxg4!
Bxg4 12. Qxb7. If, however, instead of 10. ... f3, Black responds
with 10. ... Qxh4, then the other side may increase his pressure
by the simple 11. Rxf4) 10. hg hg 11. Nxg5 Nxe4 (25).
This is one of the crucial positions in the variation. The

It would seem that Black has reliably masked the f-file, and

16. Nf5 (30)
White has a dangerous attack, as in Tchigorin—Schmidt
(Berlin, 1881).
Along with other continuations 7. ... Nc6 (instead of 7. ...
Ne7) also gives a great scope for both analytical search and prac-
tical experiments. For example, after 8. g3 g4. 9. Nh4 f3 10. Na3
(also interesting is 10. Qb3) 10. ... Bf6 (if 10. ... Nf6, then 11.
Bd3 and the White Knight on a3 is headed, via c2—e3, for f5) 11.

unbreakable) 11. ... Bxf5 12. ef d5 13. Bd3 Qd7 14. Bf4 gives
chances for both sides, analysis by N. Glazkov (31).
To sum up, by playing 4. Bc4 White may start weird compli-
cations, while Black has sufficient resources to defend himself. A
number of variations with possibilities for exciting attacks may
also arise after 4. h2—-h4 (32).
Black should not respond 4. ... f6?, because after 5. Nxg5!
his game would fall to pieces. We consider now the variations,
arising after 4. ... g5—g4.

 THE ALLGAIER GAMBIT
1. e4 e5 2. f4 ef 3. Nf3 g5 4. h4 g4
5. Ng5 ... (33)
The Austrian master Johann Allgaier was the first to analyze
this line in detail in the book Neue theoretisch—praktische Anwei-
sung zum Schachspiele (New Theoretical and Practical Manual of
the Chess Game), published in 1795.
5. ... h6
Striving for material gains at once. The Italian theorist Do-
menico Lorenzo Ponziani in his book II giuoco incomparabile de-
gli scacchi (The Incomparable Game of Chess), which appeared
in 1782, mentioned the move 5. ... d5, but he only considered the
replies 6. e5 and Qxd5. Two centuries later, Master-Candidate
V. Selivanovsky (from Moscow) gave the analysis of this line in
keeping with the modern understanding of the game. After 6. ed
he examined the reply 6. ... Nf6 which gives Black good chances.
The continuation 5. ... Nf6, 6. Bc4 d5 7. ed (7. Bxd5 Nxd5 8.

Black should hardly complain (34).
The best answer to 5. ... Nf6 is 6. e5. For example, 6. ...Qe7
7. Qe2 Nh5 8. Nc3! and if 8. ... Ng3, then 9. Qc4 Qxe5+ 10. Be2
d5! (White has a superior game after 10. ... Nxhl 11. Qxf7+ Kd8
12. d4 Qg7 13. Bxf4 Qxf7 14. Nxf7+, while 12. ... Qxd4 is
strongly met by 13. Bxf4) 11. Nxd5 Nxe2 (35).
Is there a lover of chess who wouldn't like so tense a battle?
Now 12. Qxe2 is the most reasonable try, leading, after 12. ...
Qxe2+ 13. Kxe2 Na6, to a roughly equal game.
But couldn't Black have a snack of the White Rook after 9.
Qc4 (36)? Well, in the event of 9. ... Nxhl 10. Nd5 Qxe5+ 11.
Be2 c6 (or 11. ... Na6 12. d4 Qd6 13. Bxf4 Qc6 14. Qb3, and it is
hard for Black to repulse the attack) 12. Nc7+! Qxc7 13. Qxf7+
Kd8 14. Qf6+ Ke8 15. Bxg4, White would secure a draw, but he
may bid for more.
6. Nxf7 Kxf7 (37)
Thousands of games have been played with this line. Black
has an extra Knight, but White's threats are quite dangerous and
hard to parry.
Here are two illustrative examples:

dubious, is 9. Bxb7? Bxb7 10. Qxg4+ Kf7 11. Qh5+ Ke7 12.
Qe5+Kd7 13. Qxh8 Nf6, and White is in a spot. Unplayable is
also 13. Qf5+ Kc6 14. Rh3, in view of 14. ... a5, and the Black
King escapes from pursuit) 9. ... f3! (Black, in his turn, aims to
destroy the opponent's K-side position) 10. gf Nf6 11. Nc3 (or 11.
Bb3 Nc6 12. c3 Qd6 and on 13. e5 it is Black who starts playing

the "Drawing Master" (this title was conferred upon K. Schlech-
ter by Tarracsh) fell into a cunning trap which, by the way, shows
how much venom is contained in gambit schemes. Their game
went on 16. ... Qf6? 17. Rxg4+ Kh7 18. Bg8+!, and
White's chances are as good as Black's: 18. ... Rxg8 19. Rxg8

This move had already been studied and used by the masters

On the 7th move Black could play the stronger 7. ... d6 (in-
stead of 7. ... Bh6), but even then, believes Keres, 8. Nxf7 Rxf7

We have, by now, considered merely a few of the classical
lines in the King's Gambit and from these variations, rooted in
the distant past, the reader can doubtless form an idea of the
great diversity of colorful plans and fantastic ideas hidden in this
immortal gambit.
Let us now turn to some systems of play that gained popu-
larity in this century. In these systems, Black rejects the "explosi-
ve" 3. ... g7—g5 and is ready to give back the "Greek gift"—the
Pawn on f4.

This is how the Keres—Alekhine game (Saltzburg, 1942) de-

All these methods of playing form an integral part of the ex-
tensive section of opening theory which is referred to as the
King's Knight's Gambit. The variations presented in this book
constitute a very small part of the analyses devoted to this gam-
bit. We are sure that all the possibilities that have been dis-
covered in this opening have not by far exhausted the romantic at-
tacking theme originated by the Pawn sacrifice 2. f2—f4. The re-
mark made by the Soviet chess master A. Rabinovich that "the
King's Gambit is very far from becoming outdated and will again
find numerous adherents" (Modern Openings, 1949) still rings
true.
And now the King's Bishop's Gambit comes on the agenda.

Some lines arising from White's previous moves can be
traced in the manuscripts of chess games, collected, ultimately or-

ganized and published by the celebrated 17th-century Italian
master Gioachino Greco. Here is how the idea behind the
Bishop's manoeuvre was explained by the well-known Russian
player Schiffers, "In the King's Knight's Gambit 3. Nf3 prevents
the Queen from checking on h4. In the King's Bishop's Gambit
this check is allowed so that, upon withdrawing his King to fl,
White could drive the Queen back by Nf3, thus gaining time for
development."
A
1. e4 e5 2. f 4 e f 3 . Bc4
3. ... Qh4+
In the remote past this check was taken for granted.
Centuries-long experience has shown, however, that Black's
attack 3. ... Qh4+ is far from the best. As Jose Raul Capablanca
put it, "the Black Queen is brought into action before the minor
pieces. Such play entails incalculable complications, whose out-
come is always doubtful".
4. Kfl d6
The sharp 4. ... g5 allows White good possibilities by 5. Nc3!
For example, 5. ... Ne7 6. d4 Bg7 7. g3! fg 8. Kg2!, as in the
Paulsen—Kolisch game (1862). Black is in great difficulties. In-
stead of 5. Nc3 White can continue 5. Nf3 Qh5 6. d4 or 6. h4 on
which 6. ... h6? is bad, because of 7. Bxf7+ Qxf7 8. Ne5, fol-
lowed by 9. Qh5+. The correct reply is 6. ... Bg7.
5. Nc3 ...
Or 5. d4 Bg4 6. Qd3 Nc6, as occurred in a match game be-
tween MacDonnell and La Bourdonnais (London, 1834). There
may follow 7. Bb5 Bd7 8. Nf3 Qh6 9. Nc3. For the sacrificed
Pawn White has a dangerous initiative.

It seems he was right.
After 1. e4 e5 2. f4 ef many chess lovers are attracted by the
reckless thrust 3. Qf3 (76).
The correct and highly instructive method of organizing
Black's counterplay is associated with taking advantage of the
vulnerable position of the White Queen, which was prematurely
brought to the first line of attack. There may follow 3. ... Nc6 4.
c3 Nf6 5. d4 d5 6. e5 Ne4 7. Bxf4 f6 (Black may, of course, choose

with a tremendous lead in development for the sacrificed Pawn.
We have acquainted the reader with variations in which
Black fearlessly captures the Pawn on f4. This was the King's
Gambit Accepted. But, as the ex-Champion of the World Tigran
Petrosyan used to say, "chess is not checkers, one is not obliged
to capture". The King's Gambit Declined is a method of opening
such that the game does not develop quickly and does not require
that Black should be very precise on the first moves. In this case,
White's problems are simpler, because the material balance is not
disturbed.

and 11. ... Bxc2, then it is met by 12. Rcl (81), followed by 13.
Rxc7. The Black Queen is shut "in a steel cage", and it is hard to
say how it could escape.
Instead of 8. d4, less convincing is 8. Ng6+ Be7 9. Nxh8. The

 2. f4 d5 (88)
This counterblow was introduced into master chess by the
Austrian player Ernst Falkbeer in the mid-19th century. The idea
behind his counter-gambit is positionally justified: if White cap-
tures the Pawn on d5, Black will advance his centre Pawn, imped-
ing the development of his opponent's K-side pieces, weakened
by the advance f2—f4.
Along with these specific considerations, we should recall
how Em. Lasker explicates the general grounds of all the
counter-gambits, "When a gambit is offered to an attacking
player, he finds it desirable to further complicate the situation by
offering his own gambit in return. The Falkbeer Counter-Gambit
is a direct result of this psychology."

Instead of developing his King's Knight to f6 (5. ... Nf6),
Black should pay serious attention to the alternative ... Ne7. For
instance, there may follow 5. ... Bd6 6. d4 Ne7 7. dc Nbxc6 8. d5
Nb4 9. Bc4 Bf5 10. Nd4, with a sharp game in which White's
chances should still be preferred. In the Banas—Knezevic game
(Stari Smokovec, 1979), White continued 9. Bb5 + , but after 9.
... Bd7 10. Bxd7+ Oxd7 11. 0 - 0 Rd8 Black had no problems
worthy of notice.
4. d3 ...
This move, first introduced by Wilhelm Steinitz against
Gruber (London, 1872), is today considered to be the strongest
one. The elaborate analysis of the ensuing variations made by P.
Keres has contributed greatly to establishing this reputation.
The line 4. Nc3 Nf6 5. Bc4 Bc5 6. Nge2 0 - 0 7. d4 ed 8. Qxd3

similar to those of the King's Gambit but, perhaps, are more
favorable for Black. The point is that the move 2. Nc3 does not
contribute much to the preparation of a K-side attack, whereas
the Black Knight's post on c6 is important for protecting the point

 This is the surprising invention of the first World Chess
Champion Wilhelm Steinitz, introduced by him in 1867. The ex-
travagant idea behind the Steinitz Gambit is to make a strong
Fawn centre at the expense of rejecting castling. As a result, the
White King is often obliged to take long journeys. Steinitz main-
tained, however, that the King is a strong piece, and is quite ca-
pable of defending itself even in the opening phase. Still, by tak-
ing advantage of the exposed position of the White King, Black
may obtain a good game.

bit in the Second Hand", as it was called in the 19th century, was
discarded as incorrect.
In the early 20th century the Latvian masters, especially C.
Behting and G. Mattison, revealed new interesting possibilities in
variations long declared unsound, thus reviving the old gambit.
Considering the great contribution of Latvian chess players
to the development of this opening, the FIDE Congress (1933)
named it the Latvian Gambit.

 BLOW IN THE CENTRE
In this chapter we consider gambits connected with a sac-
rifice of White's centre Pawn on d4. Jose Raul Capablanca
pointed out in his manual that the King's and Queen's gambits
are in fact close relatives: White advances the Bishop's Pawn (f2
or c2), striving to undermine the opponent's stronghold in the
centre and set up a solid centre with a lead in development. How-
ever, the specific character of the initial position makes the se-
quence 1. d4 d5 2. c4 a false gambit. Obviously, the sacrifice of
the Pawn on c4 is sham; after 2. ... dc it would be impossible for
Black to protect his gain. Consider, for example, the variation 3.
e3 b5 4. a4 c6 5. ab cb 6. Qf3 wins.
Naturally, in this book we do not analyze the Queen's Gam-
bit. In what follows, we are concerned with the true gambit
systems based on blows in the centre.
THE SCOTCH GAMBIT
1. e4e5
2. Nf3 Nc6
3. d4 ed
This variation was given already in Greco's MS. Later the
Italian master G. Lolli (1763) considered some other continua-
tions of secondary importance, but the entire opening was seri-
ously developed after the correspondence match Edinburgh—
London (1824), in which this gambit (named "The Scotch Gam-
bit" in memory of this event) was used by the Scottish side.
Exchanging the Black Pawn on e5, White strives to open
lines for the Bishops and the Queen. After 4. Nxd4 there arises
a lively game, in which both sides have their trumps. We are in-
79
terested, however, in a gambit handling of this opening, a gambit
which gained considerable popularity in the mid-19th century.

K. Goering, a 19th-century German master, was the creator
of many ideas originating from this enterprising sacrifice. That is
why the old opening handbooks attributed the name of Goering
to this gambit. In recent years there has been a great upsurge of
interest in this move, since new attacking lines for White have
been found.
4. ... dc
Those of a quiet disposition will find the prudent 4. ... d3
more to their liking. There may then follow 5. Bxd3 Bc5 (5. ... d6
cedes the initiative to White. For example, 6. 0—0 Nf6 7. Nbd2

is hardly correct, as was already pointed out by Emanuel Lasker.
There may follow 6. Bc4 d6 7. Bg5 Qd7 8. Qd2 and, castling long,
White will obtain real attacking chances. It will not be easy for
the Black King to find a safe shelter. Instead of 7. Bg5, White
may also play 7. Qb3 Qd7 8. Nd5 with a good game.
Black may, of course, respond 5. ... d6, which leads, after 6.
Bc4, to a complicated game in which White has quite good pros-
pects (114).
For example,

played by a Danish jurist in Jutland in the 1830s and utilized by
Lindeln, a Swedish player, in the game (1859) against Swanberg,

Scotch Gambit.

5. Bxb2 ... (119)
Having sacrificed two Pawns, White has taken the lead in de-
velopment and his Bishops are aiming menacingly at Black's K-
flank. Black now has two courses to follow: he can cither attempt
to put up a stout defence, while hanging on to his material advan-
tage or, "defuse" White's attack by the above-mentioned
method, i.e., by giving back the extra material and forcing a
series of exchanges; he may thus hope to obtain a quiet, safe
game.
In spite of its outward attractiveness, the Danish Gambit is
in fact quite harmless for Black.
Here is what Mikhail Tchigorin wrote about it, "Good
players have the sense, while in a serious contest against strong
opponents, not to risk offering the Danish (North) Gambit. The
charming games, published from time to time in the press, only
demonstrate a weak defence of Black, and, as a result, White's
attacks have been finished so brilliantly."

 CAPTAIN EVANS'S SECRET
The stern face of a "real old salt", lashed by the ocean
winds, looks at us from an old lithograph. This is Captain William
Davies Evans who popularized this gambit in 1824 during the
London—Edinburgh match.
Here is what Era. Schiffers wrote about this opening, "This
gambit is extremely interesting. It gives rise to lively attacks and
counterattacks. La Bourdonnais, Anderssen and Morphy wil-
lingly adopted it."
Among other chess players who greatly contributed to the
theory of this gambit Schiffers mentioned Steinitz and, especially,
Tchigorin.
1. e4e5
2. Nf3 Nc6
3. Bc4 Bc5
4. b4 ... (128)
Schiffers thus described the idea behind the Evans Gambit,
"The Pawn is offered to gain a tempo for building a Pawn centre.
This move permits White to open the el—a3 diagonal for the
Bishop, which in many variations occupies a strong post on b2 or
a3. In some cases, the open b-file is advantageously occupied by
the Rook. Whether the Pawn sacrifice is correct is the question;
it has not yet been answered. At any rate, the attack is so strong
and diverse that one may safely employ it in a practical game."
Innumerable games have been played, and new analyses
have been published, of which those by the Soviet masters and
grandmasters Levenfish, Keres, Kan, Konstantinopolsky,
Nenarokov, Ravinsky and Sokolsky are of special importance.
And yet we have no definite answer. Captain Evans's secret is
still unsolved.
 Let us begin our consideration with the capture of the bold
Pawn.
4. ... Bxb4
The capture of the Pawn with the Knight only results in
transposing to the main line after 4. ... Nxb4 5. c3 (not, of course,
5. Nxe5? Qf6! winning) 5. ... Nc6 6. d4.
Modern chess theory, as we have already mentioned, has
suggested the following method of playing against gambits: the
"Greek gift" is accepted, but then it is returned to simplify the
position or to create counterplay. This method is widely used also
in the Evans gambit.
5. c3 ...
This is a logical development of the basic idea. Tartakower
advocated 5. 0—0, but then 5. ... Nf6 6. d4 ed 7. e5 d5 gives Black
good play (Pinkus—Marshall, New York, 1926).

For a long time this old move was rated as one of minor im-
portance, but today it has many adherents. The effect of Bishop's
retreat to d6 produces a dull impression, and yet this unnatural
move was repeatedly adopted even by great masters.

ficult for White to demonstrate that he has sufficient compensa-
tion for the sacrificed Pawn (Anderssen—Zukertort, Berlin,
1868);
(b) 9. Bb2 Nge7 (simpler is 9. ... Na5 which transposes, after
10. d5, to the line just considered. But 9. ... Bg4 is weak, in view

According to Keres, Black has a positional advantage. This as-
sessment is confirmed by the variation 14. Nc3 Qxg5 15. Qa4+ c6

threats of 15. R e l and 15. Ba3, Black is in great difficulties. In
the supplements to Dufresne's manual, published in St.
Petersburg in 1898, Tchigorin pointed out that 14. ... a6 is weak,
for after 15. Rel Ne7 16. d6 ab 17. Nxf7 Black's position is in

This manoeuvre, in full conformity with modern chess
strategy, was suggested by the English master B. Cafferty. Black
finds it difficult to coordinate his forces. In times past, White
used to play 14. Khl Nb4 15. d5 and here 15. ... Ng6! offers Black
sufficient counterplay. Weaker is 15. ... Bxe3? 16. fe, as in the

its disadvantages, too".

This is Howard Staunton's old move, enthusiastically recom-
mended by A. Anderssen. This continuation was revitalized
when Lasker found a convenient method of equalizing with the
Black pieces after 6. 0—0 (considered the best in decades).
Lasker's idea is that after 6. ... d6 7. d4 Black does not hang
on to his extra Pawn, but gives it back by 7. ... Bb6!, obtaining a
good endgame. Here is how it can happen: 8. de de 9. Qxd8+

ferred 9. ... Qe7) 10. Bg5 Qg6 11. Bd5 Nge7 12. Bxe7 Kxe7 13.

 To sum up, we should say that the exciting Evans Gambit
leads, as a rule, to sharp play with varied combinative themes in-
volved.
It is not a coincidence that Paul Morphy, Adolf Anderssen
and Mikhail Tchigorin, perhaps the most imaginative chess
players of their time, liked this gambit and adopted it regularly in
their tournament and match games.
That Tchigorin (as White) used the Evans Gambit 23 times
playing against the first World Chess Champion Steinitz is an es-
tablished fact. The score was +12 -6 =5 in favor of the great
Russian master. Besides, many of these encounters bore a princi-
pled and creatively controversial character, the more so that
Steinitz often pronounced the Evans Gambit "incorrect".
 IN THE HEAT OF COMBAT
Up to now we have considered the gambits arising in so-call-
ed "open" games (i. e., after 1. e4 e5). However, the desire to trip
the opponent up on the very first moves has clearly manifested it-
self also in "semi-open" (1. e4 e6; 1. e4 e5; 1. e4 Nf6, etc.) and
"closed" (1. d4 d5; 1. d4 Nf6, etc.) games.
The chess masters of the Renaissance regarded the old Sici-
lian Defence as an attempt to prevent White's occupation of the
centre with his Pawns and, above all, as a means of avoiding the
formidable King's Gambit. But from time immemorial it has
been known that even after the relatively "safe" reply 1. ... c5
Black's life was far from serene. The ancient manuscript, dated
1623, mentions the Pawn sacrifice 2. b4, tricking the Black
c-Pawn by a decoy from the vital central squares. Moreover, this
manoeuvre allows the dark-squared Bishop to put pressure on
the long diagonal by developing it to b2. This method received
the name of the Sicilian Gambit.
1. e4c5
2. b4cb
Theoretical studies and practice of the gambit have proved
that Black may accept this offer without misgivings. White has a
good game after the timid 2. ... b6. For example, 3. be be 4. c3 e5
5. Nf3 Nc6 6. Bb5. He also obtains an active position in the case
of 2. ... e5 3. be Bxc5 4. Nf3 d6 5. c3, building up a powerful
Pawn centre. An attempt to counter with 2. ... d5 would be pre-
mature—3. ed Qxd5 4. Nc3 Qe5+ 5. Qe2 Qe2+ 6. Bxe2, and on
6. ... cb White has the nasty retort 7. Nd5.

Still, it would be groundless to bury the sacrificial idea (b2—

the Pawn is offered later on, when the King's Knight is developed
to f3.
The modern handling of the gambit is as follows:

In recent years, a different plan of dashing operations, orig-
inally proposed by several Viennese masters already in 1889, and
subsequently elaborated by the Spanish master Morra, has again
become popular. The Morra Gambit leads to sharp positions
where it is far from easy for Black to beat off White's attack.

THE ALBIN COUNTER-GAMBIT

1. d4d5
The gambit invented by the Swedish master Englund, 1. ...
e5, is unsound. After 2. de Nc6 3. Nf3 Qe7 White quite easily

No. 159

gains the advantage by 4. Nc3 Nxe5 5. e4, and the Black Queen
is disadvantageously placed on e7. White may also retain the of-
fered Pawn by playing 4. Qd5, and 4. ... f6 is met by 5. ef. There
are no vulnerable points in the White camp, and the tactical
threats Black has at his disposal are mere pinpricks.
2. c4 e5
This is the ingenious invention of the Rumanian-born master
A. Albin. The counter-gambit was introduced towards the end of
the 19th century and immediately attracted the keen attention of
both theorists and players. The idea behind the Pawn offer is to
hamper free development of the White pieces, and this is re-
vealed by Black's next move.

Here, too, 5. e3 is unfavorable, because of 5. ... Bb4+ 6.

example,

h3 Bb4+ 7. Nbd2 Nge7 8. a3 Bxd2+ 9. Qxd2 Ng6 10. 0 - 0 - 0 .

li. Bg2 Bg7 12. 0—0 Nxe5 13. Nxe5 Bxe5 14. b4 (Lasker—
Alekhine, St. Petersburg, 1914). Black has restored the material
balance, but White retains a strong pressure on the Q-side (161);
(c) 5. a3 Bg4 6. b4 (or 6. Nbd2, transposing back to the
variation "b")
5. ... Bg4
The reckless 5. ... f6 leads to curious complications after 6.

Nb4 11. a3! Bxbl 12. Nxbl Nc6 13. b4 is very promising to White,
for Black is incapable of holding his outpost on d4 (the threat is
14. b5, while 13. ... 0—0—0 would be countered by 14. Bg5), and
White will have two Pawns for the exchange, all his pieces being
favorably placed.

shattered (Kozlovskaya—Mosionzhik, 1971).
7. ..: 0—0—0 (162).
Q-side castling is a link in Black's strategic plan. It is pre-
cisely for this reason that White has developed his King's Bishop
to g2, from where he can take aim at the vulnerable point b7.
Black cannot avoid castling Q-side, however, for such is the logic
of the resultant position. If 7. ... h5, as Simagin played against
Sokolsky (1953), then 8. a3 h4 9. Bf4 hg 10. Bxg3 Nge7 11. b4,
and White gets his blow in first.
The manoeuvre 7. ... Nge7 has been regarded as dubious
since the Tolush—Horn correspondence game (1953—54). In
view of 8. b4! Nxb4 9. e6! Bxe6 10. Ne5 Qc8 11. Qa4+, it would
be fatal for Black.

possible speed. On 3. ... Bf5? White would answer 4. f3, and
atter 4. ... ef 5. Qxf3 Bc8 6. Bf4 Nf6 7. 0—0—0 he would have an

This very interesting move was suggested by the Hungarian
master Abonyi in 1917. The opening was then extensively
analyzed by several Hungarian masters, notably by the talented
and original Julius Breyer.
This gambit was successfully adopted until Alekhine dealt it
a heavy blow demonstrating in a number of games a clear-cut
method of obtaining the better game for White. Today theorists
consider this gambit a dubious opening.
3. de Ng4
The risky jump 3. ... Ne4, suggested by the German master
I. Fajarowicz, has not stood the test of time. White can simply
play 4. a3, and his Pawn on e5 would be immune from attacks.

Striving to retain the extra Pawn, White should be ready to
parry Black's tactical thrusts for some time. Alekhine, however,
was of the opinion that the best line is 4. e4. Justifying his choice,
he wrote, "White returns the Pawn to take control of the point d5
instead." At the same time, we note that the central square d5 is
Black's "Achilles's heel" in a number of other variations of the
gambit. Thus, the well-known game between Alekhine and Seitz
at Hastings (1925—26) continued: 4. ... Nxe5 (or 4. ...d6 5. ed

THE BLUMENFELD GAMBIT
This gambit, invented in the 1920s by the Russian master B.
Blumenfeld, is based on a sound positional idea: Black wishes to
take possession of the centre at the cost of a Pawn. The Blumen-
feld Gambit also served as a prototype of the Volga Gambit,
which has become very popular with imaginative, enterprising
players.

THE STAUNTON GAMBIT

This Pawn sacrifice was introduced by the outstanding En-
glish master Howard Staunton in the first half of the 19th century.
He considered this sacrifice as an effective method of obtaining
active play against the Dutch Defence. The gambit offers White
good attacking chances, and it has found its place in the arsenal
of offensive weapons of many aggressive players. The centre
Pawn sacrifice is entirely justified, because Black's initial move
... f7—f5 weakens to some extent Black King's defences.

fractory position.
The continuation 4. Bg5 has been employed quite often. It is
wrong for Black to reply 4. ... d5, in view of 5. Bxf6 ef 6. Qh5 + ,
but 4. ... g6 (175) would be quite safe for him.
Of course, he would be content with the mercenary 5. Bxf6

tinuing 5. f3 ef 6. Nxf3 d5 7. Ne5. Alekhine opted for the im-
mediate assault 5. h4 Bg7 6. h5. An alternative plan was worked
out by the Soviet master A. Khachaturov, who suggested that
White should play 5. Bc4 to answer 5. ... Bg7 by 6. Qe2 c6 7. Bxf6

As the Staunton Gambit has a great destructive power, many
masters avoid it by playing 1. d4 e6 2. c4 f5, at the "risk" of find-
ing themselves (after 2. e4) on the "territory" of the French De-
fence.
THE FROM GAMBIT
1. f 4 e 5
Just as in the Staunton Gambit, the sacrifice of the centre
Pawn here is based on the fact that White's initial move has
weakened the position of his King. The gambit was proposed by
the Dutch master K. From in 1862. In 1874, his compatriots, mas-
ters G. Nielsen and S. Serensen published analyses devoted to
this opening, and in 1892 Emanuel Lasker found an interesting
improvement, making Black's attack more intensive.

 MODERN IDEAS
In essence the history of chess culture is the history of ideas
that originated from practical experience. The ideas of the
strategy and tactics of the game do not disappear without trace,
of course, they continue to be enriched in content and brought up
to date. We have already mentioned that this is also quite true of
gambit ideas, which occupy a prominent place in modern theory
and practice.
The process of renewal has not only embraced a number of
old openings, but also manifested itself in the invention of new
gambits in which the centre of gravity is shifted from direct attack
against the enemy King to the preparation of "launching pads",
from which future attacks may start.
It would seem that the theory of the "tedious" symmetrical
Four Knights' Game, for many decades serving as a refuge for
lovers of a quiet life, should be exhausted. But a brilliant idea,
which spread like wildfire across the boundary between the Four
Knights' Game and the Scotch Gambit at the end of the 1940s,
announced the appearance of a new gambit. The old truth was
confirmed once again that complete knowledge implies also some
understanding of the depths of our ignorance.

COCHRANE'S GAMBIT
This gambit opening was introduced by the Scottish master
John Cochrane (1798—1878), noted for his daring style of play.
This is how he tried to obtain direct attack against the solid Pet-
rov Defence: after 1. e4 e5 2. Nf3 Nf6 3. Nxe5 d6 he did not with-
draw his Knight e5 to f3 or c4, but sacrificed it on f7, assailing the
Black King at once (186).
In the spirit of his time, Cochrane answered 4. ... Kxf7 by
the unsophisticated 5. Bc4+ which, however, could only succeed
under Black's weak and ill-considered defence. The reason is ob-
vious: there are few pieces participating in the offensive.
By playing 5. ... d5! 6. ed Bd6 7. 0—0 Rf8 8. d4 Kg8 Black
can easily parry all threats, retaining his material advantage. If
White continues 6. Bb3 instead of 6. ed, then 6. ... Bg4 7. f3 Be6
8. e5 Nh5 gives Black superior play.
For over a century the Cochrane Gambit remained in the
shade, until D. Bronstein paid attention to the fact that after the

No. 186

142
blow on f7, aimed at exposing the Black King, White should not
strive to create petty tactical threats to the enemy monarch, but
should instead choose the positional 5. d4 to form a strong Pawn
centre and only then, under its cover, prepare his attack. This
idea, which was suggested by Thorold as far back as 1876, and
was not duly appreciated at the time, has been analyzed and
elaborated by the Soviet chess player Alvis Vitolinsh. It has been
found that Black's defensive task is, by no means, as simple as it
might seem. We should point out at once that after 5. d4 Black
would not play 5. ... Nxe4, because of 6. Qh5+ and if 6. ... g6,
then 7. Qd5+.
The modern treatment of the Cochrane Gambit can be illus-
trated by the Vitolinsh—Anikayev game (Frunze, 1979), which
continued 5. ... g6 6. Nc3 Bg7 7. Bc4+ Be6 8. Bxe6+ Kxe6 9. f4
Kf7 10. e5 Re8 11. 0—0 (187).
At this juncture the withdrawal of the Black Knight from f6
may, after f4—f5, create insurmountable difficulties for Black.
There followed 11. ... Nc6 12. d5 de 13. dc Qxdl 14. Nxdl be,
with about level chances.
Instead of 12. d5, White can also continue 12. ef, for exam-
ple, 12. ... Qxf6 13. Nb5 Re7 14. d5, or 12. ... Bxf6 13. d5. Of
course, Black's possibilities are not confined to 5. ... g6. An in-
teresting, sharp game may result, for instance, from 5. ... c5!?
(188).

ed Bd6 8. 0 - 0 Re8) 6. ... Qa5+ 7. Nc3 Qxc5 8. Be3 Qa5 9.
Bc4+, and White's threats may become quite dangerous.
In any case, the Cochrane Gambit has now got its "second
wind"; and this example once again shows how fruitful the
dynamic ideas contained in gambits may be and how many in-
teresting possibilities they may introduce, even in forgotten and
rejected lines.
The Jaenisch Gambit... This is a case in point!
A subsystem of the Ruy Lopez, it knew times of glory and
decline.
1. e4 e5
2. Nf3 Nc6
3. Bb5 f5 (189)
This sacrificial continuation was invented and introduced
into tournament practice by the Russian master Karl Jaenisch
(1813—72). He published his analyses in 1847.
The bold thrust 3. ... f5 at first attracted much attention and
was widely employed by chess players; then, however, it became
apparent that the gambit had its dark side, too. After the capture
4. ef Black, as a rule, gets a promising game by playing 4. ... e4.
For example, 5. Qe2 Qe7 6. Bxc6 dc 7. Nd4 Qe5 8. NO, and now

No. 189

144
the Black Queen may either come back home without fuss (8. ...
Qe7) or capture the Pawn on f5.
In 1902 the German theorist K. Dyckhoff suggested, how-
ever, a new plan, starting with 4. Nc3, which filled the supporters
of the Jaenisch Gambit with despair. Indeed, the main line runs
as follows: 4. ... fe 5. Nxe4 d5 6. Nxe5 de 7. Nxc6 Qd5 (190) 8. c4
Qd6 9. Nxa7+ Bd7 10. Bxd7+ Qxd7 11. Qh5+, and White has
the advantage after both 11. ... Kd8 12. Qa5! and 11. ... g6 12.
Qe5+ Kf7 13. Nb5 (or 13. Qxh8Nf6 14. Nb5) 13. ... c6 14. Qd4!
The complications that arise in the Dyckhoff Variation are
great, but the outcome is usually tragic for Black. It remained so
until in the late 1940s Bronstein successfully revitalized the varia-
tion by suggesting a number of counterplay possibilities for
Black, leaving him some good prospects, too.
The line 4. Nc3 fe 5. Nxe4 Nf6 (191), which has quite re-
cently been re-introduced into master play, has, indeed, become
a full-fledged gambit. Several years ago theorists accompanied
Black's last move with a "?" sign, but it has turned out to be
wrong.
6. Nxf6 Qxf6!
Black should play exactly so and not 6. ... gf, although in The

No. 190 No. 191

145
Manual of Chess Openings (Panov and Estrin) we read, "... but
not 6. ... Qxf6, because of 7. Qe2, and Black loses a Pawn."
In fact he does not lose, but sacrifices the Pawn obtaining de-
finite compensation, which is evident, for instance, from the fol-
lowing variation:
7. Qe2 Be7 8. Bxc6 be 9. Qxe5 Qf7 10. d3 (or 10. Qxc7 0—0
11. 0—0 Qg6) 10. ... d6. For the "lost" Pawn Black has the
Bishop-pair and his pieces are actively placed.
On 8. Bxc6 Black also has the following interesting alterna-
tive 8. ... dc 9. Qxe5 Bg4 10. Qxf6 Bxf6 11. 0 - 0 0—0—0 12. R e l
Rhe8 with good prospects (Darga—Parma, Buenos Aires, 1978).
White may continue 9. Nxe5 0—0 10. 0—0 Bd6 11. d4 c5 12.
Be3 Be6 13. f4, which is more favorable for him, as compared
with the previous variation.
The continuation 5. ... Nf6 is now the object of profound
study, and it is not excluded—it will open new horizons in the old
gambit.
A similar process of reappraisal of values has taken place in
the Slav Gambit.

"The position has already given quite a number of nasty sur-
prises after the practical verification. Nobody has succeeded in
finding its true solution," wrote the noted Soviet theorist
V. Ragozin in the 1930s. This has remained true in our day.
In the last century, the Slav Gambit was looked upon as a
sharp, though not quite sound, opening. This assessment was
connected with the fact that White at once attempted to
checkmate the enemy King while Black searched for means to de-
fend himself against mating attacks. Only when the Gambit
began to be treated on the basis of modern concepts has it be-
come not only a tactical, but also a strategic weapon.
146
 Let us again turn to Ragozin's thoughts about the diagram-
med position:
"We here see the absence of symmetry in the Pawn con-
figuration and an unequal development of the pieces and, above
all, a sharp disbalance in the sides' forces, both quantitative and
qualitative. Only a concrete analysis may give us the key to the
solution of these positions."

"The idea behind this move, analyzed by several players

Nxf7+ Ke7 18. Nxh8 Rxh8 19. Bc3.
Black is a Pawn ahead, but the activity of White's pieces
compensates him for his material loss.
Let us briefly discuss two more points concerning the gambit
under consideration. In some variations, the reader's attention is
drawn to the fact that capturing the Pawn on g2 is rather risky.
However, this capture is thematic in almost all variations of the
gambit. The reader is, therefore, advised to look more carefully
into the possibilities arising from the capture—for his own
benefit.
What would happen if, instead of the conventional 8. Be2,
White adopts the move 8. Ne2?, suggested by the Peruvian mas-
ter E. Canal (198).
In this case, 8. ... Qxc4? would be suicidal for Black, for in-
stance, 9. Qd6 Nd7 10. Nc3 Qh4 11. 0—0—0 Qe7 12. Ne4, and it
ls hard to suggest anything playable for him. On 8. ... Na6 the
•°ng raid 9. Bf8! is highly unpleasant for Black. For example, 9.
••• Qg6 10. Qd2 Qf6 11. Bd6 Ne7 12. 0 - 0 — 0 0 - 0 13. Nc3 Rd8
^ Bd3 Ng6 15. Ne4 Qd4 16. Qg5, and Black is quite uncomfort-
as in the Terpugov—Smyslov game, Moscow, 1949. Instead
151
of 9. ... Qg6, he should play 9. ... Ne7. This may be followed by
an exchange of heavy blows, as occurred in the Kholmov —
Novotelnov game (Moscow, 1951): 10. Bxg7 Nb4! 11. Qd6! (on
11. Bxh8, 11. ... e5 is very powerful) 11. ... Nd3+ 12. Kd2 Nf5
13. Qxd3 Qxd3+ 14. Kxd3 Nxg7 with chances for both sides.
The safest reply in the diagrammed position is 8. ... Nd7.
There may follow 9. Qd6 c5 (it does not pay to be greedy: the
Berliner—Steinmeyer game (New York, 1962.) continued 9. ... e5
10. 0 - 0 — 0 Qg6 11. Qc7 Qe6 12. Ng3 f5 13. Rd6 driving the
enemy back everywhere) 10. Bxc5 Nxc5 11. Qxc5 Bd7. Euwe
considers the game roughly level.
We shall conclude our talk about this opening system, which
harbours a great variety of interesting plans of attack and de-
fence, by briefly describing a peculiar Slav Counter-Gambit. In
the position after White's 8. Be2 the reply 8. ... c5 (199) deserves
attention. Variations arising from this continuation have so far
beer, little analyzed, and they leave much scope for independent
searches. There may follow 9. Bxc5 Qxg2 10. Qd4 (on 10. Qd6

Pawn (Sapundzhiev—Popov, Sofia, 1961).
In conclusion, let us consider several gambits, which have
been invented recently.
THE SCHARA—HENNIG GAMBIT
1. d 4 d 5
2. c4 e6
3. Nc3 c5
4. cd ...
This continuation leads, after 4. ... ed 5. Nf3 Nc6 6. g3, to
complicated positional play. An interesting, though (according to
the theory) not quite sound, attempt is the bold Marshall Gam-
bit: 5. e4 de 6. d5 f5. After 7. Bf4 Bd6 8. Bb5+ Kf7 9. Nh3 a
sharp game arises, in which any side risks to break his neck.
4. ... cd (200)
The Pawn is sacrificed from positional considerations. It is
not an attack against the enemy King; it is Black's lead in de-
velopment, its control over a number of vital squares that matter.
By increasing his pressure Black can move by move create condi-
tions for a dangerous attack.

 The gambit was first analyzed by the Viennese master Schara
and introduced into master play by the German master von Hen-
nig towards the end of the 1920s. It was Alekhine who made it
popular by adopting it in the International Tournament at Bled
(1931).
However, Alekhine never overestimated the gambit's
strength. He wrote, "An interesting Pawn sacrifice. Still, the
analytical testing of the gambit has shown that with correct play
White should emerge from the opening with an extra Pawn and a
safe position."

Black's lead in development is noticeable and his threats to
invade with the Knight to b4 or d4 should not be underrated.
White should be extremely cautious. There may follow:
9. e3 Nb6 10. Bb5+ Ke7 11. Kfl! (after 11. Ba4 Bc4 12.
Nge2 b5! 13. Bdl Nd3+ 14. Kfl b4 Black's threats are very

position being very solid. For example, 10. ... Qe7 11. Be2
0—0—0 12. 0—0. The sharp 12. ... g5 may be countered with 13.
b4! Bxb4 14. Bb2. Having returned the Pawn, White has activated
his pieces and opened the lines, permitting him to attack the
Black King.
The Peruvian and the Dutch gambits, examined below, are
close relatives (or modifications) of the Schara—Hennig Gambit.

The tempting 9. ... Nxe4 10. Nxe4 ed is unplayable, in view

THE VOLGA GAMBIT
1. d4 Nf6
2. c4 c5
3. d5 b5
4. cb a6 (210)
The gambit was suggested by several Soviet players from
Kuibyshev (a city on the Volga River), notably by master-candi-
date B. Argunov. Their analysis was first published in the chess

No. 209 No. 210

160
magazine Shakhmaty v SSSR (Chess in the USSR) in 1946
(No. 2), but was received with unconcealed scepticism. The idea
behind the gambit is purely positional: Black intends to set up
some pressure on the Q-side and along the a6—fl diagonal,
create weaknesses in the White camp and, gradually exploiting
them, organize an attack. Practical testing has revealed the viabil-
ity of this plan. The attitude towards the Volga Gambit has dras-
tically changed and it can now frequently be seen in tournaments
at all levels.
As we have already mentioned, in recent years there has
emerged a tendency to treat many "classical" gambits in a spirit
of positional, strategic play, thus proceeding in accordance with
the motto "from a sharp fight to a slightly better endgame".
True, it is not always possible to achieve this, but the tendency is
there, beyond doubt.

In the event of 11. Rel Qb6 12. e4 Rfb8 13. h3 Ne8 14. Qc2

 FROM THE GOLDEN TREASURY
Many brilliant games, making history in chess, have been
played with gambits. Accordingly, we have selected 23 memora-
ble games from that golden treasury.
Consequently, in order to use the material given here the
reader must attentively analyze these instructive games to try to
understand the intentions of the opponents, find the best continu-
ations for both White and Black without being influenced by the
outcome.
Every experienced player must know that there is nothing
worse in a chess analysis than to make use of a priori proofs in-
stead of objective considerations of established facts. A chess
player who indulges in foregone conclusions is doomed to failure.
The "?" and "!" signs have been used in this chapter to de-
note some moves in the games, but they should be regarded only
as landmarks, rather than dictates.
In view of all this, dear reader, try to answer the questions
connected with the chosen games.

 THE HIDDEN AND THE OBVIOUS
(Questions Answered)
1. (1) The right continuation here is 9. c3; (2) After 12. ... h5
13. Bg5 f6 14. Bel, followed by 15. Nf4, "Black's K-side is all
messed up" (Fischer); (3) "Black snatches the initiative after
17. Bxd6 Rf6 18. Bf4 Rg6" (Fischer); (4) More exact is 23. ...
Qg3 24. Qxg3 Rxg3 and Black has the better endgame; (5) The
right defence is 26. ... Bf8 27. Qxa7 Bd6 with about level chances.
2. (1) "After 14. ... Bxc3+ 15. be Re2+ 16. Qxe2 Bxe2 White
would have interposed 17. Rbl!" (Tchigorin); (2) "On 16. ...
Bxc3+ there would follow 17. Kdl and any retreat of the Black
Queen would be met by 18. be Ne4 19. BO!" (Tchigorin).
3. (1) The right move is 8. ... Ng6 with a roughly even game;
(2) After 13. Qe2 Nf6 Black would obtain a solid position; (3)
After 15. ... ef+ 16. Rxfl Bxd6 White would win by playing 17.
Qh7+ Kf8 18. cd cd 19. Qh8+ Ke7 20. Qxg7. Equally bad is 16.
... Nf8, in view of 17. Nxf7; (4) On 17. ...Kxf7,18. Ng5+ Kg8 19.
Bb3+ is decisive.
4. (1) 13. Bd2, followed by Rael, would leave him more
chances than the move in the actual game; (2) As Botvinnik
pointed out, White should play 14. Bxf4 Bxf4 15. gf Nxc4 16.
Qxc4 Qd5 with even chances; (3) According to Botvinnik, the
best defence is 24. Qd2!, giving up a Pawn, but obtaining an ac-
tive game instead; (4) On 26. Bel, Rf6 would settle matters.
5. (1) 5. Nge2 is right here; (2) White's handling of the open-
ing is deplorable: snatching Pawns with his backwards develop-
ment may only lead to trouble. He should have continued 11.
NO; (3) 14. Nel would be more stubborn; (4) If 16. Khl, then 16.
... BxO 17. gf Rc7 and the manoeuvre Qd8—g5 would be deci-
sive; (5) 22. ... dc? is wrong, because of 23. Bd6+.
180
 6. (1) Black intends to defend his Pawn on f4 with his Knight
on g6, but the manoeuvre is too slow; (2) Better is 11. ... Qxdl
12. Raxdl Nd7 13. Bg3 Nf6; (3) Bad is 13. ... Qxc4, because of
14. Rxg7+, while 13. ... Qxe5 fails to 14. Rxe7+; (4) 15. ... Kg8
loses after 16. Qe8+ Bf8 17. Qxc8 Qxe5 18. Oxb7.
7. (1) 10. ... g5? is rather feeble, because of 11. Nexg5 (2)
14. Radl, intending the break d4—d5, would be more logical; (3)
19. ... Be6 would lead to a roughly even game; (4) But now it is
too late to play 20. ... Be6, for White would win after 21. Nxf7
Bxf7 22. Rxf7 Rxf7 23. Rfl; (5) After 21. ... Qd2 22. Qe4,
White's attack is irresistible.
8. (1) The Bishop sacrifice on f7 was suggested by Alekhine.
The point of the combination is to get two Pawns and a powerful
centre for the sacrificed piece. The Black King's position is not
safe, either; (2) After 14. 0—0+ White would retain his attack, but
the game would be double—edged; (3) In the event of 20. ...
Nxe6 21. de Qxe6 22. Qxb5 Qxe4 23. Bf2 White would have a
clear advantage; (4) On 22. ... Kf8, 23. Qc4 would be decisive;
(5) After 27. ... Kxg7 White would win by 28. Bh6+ Kxh6 29.
Qxf8+ Kg6 30. e7, etc.
9. (1) Black ought to have played 10. ... Ne7 instead, castling
Q-side being very risky for him; (2) The right move is 22. ... h4,
intending ... h4—h3; (3) If 30. ... Kxc6, then 31. Qa4+ Kb7 32.
a6+ Kb8 33. Qc6, etc.
10. (1) 13. ... 0—0—0 would be better; (2) He should have
answered 21. ... Nf6; (3) On 25. ... ab, the variation 26. ab+ Ba7
27. Rxa7+ Kb8 28. Rfxb7+ Kc8 29. Ba6 would decide the issue.
11. (1) 8. ... 0—0 could offer much stiffer resistance; (2) 14.
... Be6 fails to 15. Nxf7 and 14. Bxg5, to 15. Bxf7+; (3) After 19.
... Ng5 White would win by 20. Bxg5 Bxg5 21. Bxh7+ Qxh7 22.
Qxh7+ Kxh7 23. Nxg5+, etc.
12. (1) The variation 7. ... Bf2+ 8. Kdl Qxd5+ 9. Nfd2! f5
10. Nc3 is disadvantageous to Black; (2) He should have con-
tinued 8. Nc3; for example, 8. ... Qe7 9. Be3 and the feeble 9. ...
Nxc3? is strongly countered by 10. Bxc5; (3) To 10. Qg2, Black
may strongly reply 10. ... Qxd5 11. Be2 Nc6 12. Nc3 Qxf5; (4) 12.
... f6 would be met by 13. d6! threatening both 14. Bd5+ and 14.
Qc4+.
IS!
 13. (1) After 18. ... Be6 19. Rdgl White has a crushing at-
tack; in particular, the White Queen threatens to go to h6; (2) 19.
e6! opens the diagonal for the Bishop on b2. After 19. ... Nxd3
20. Rxd3 Bxe6 21. Rgl wins; (3) The Black King would be mated
after either 21. ... Nxe3 22. Rd8+ and 23. Rh8 mate or 21. ...
Qxc4 22. Qe8+ Rf8 23. Qxg6 mate; (4) On 22. ... cd there would
follow 23. Qe8+ Rf8 24. Bxd5+, etc.
14. (1) He should have played 8. Nc3, and if 8. ... Qh5, then
9. h3 Bd6 10. Be3 0—0—0 11. Qa4 Khe8 12. 0—0—0; (2) in the
event of 11. ... Bxh3, White would repel the attack by 12. gh
Qxh3 13. Bfl; (3) Bad is 16. Nxd4, in view of 16. ... Nxd4 with a
winning attack. An interesting alternative is 16. Rxe5 Ncxe5 17.
Nxd4 Qxg5; (4) On 22. Qd5 Black would strongly reply 22. ...
Nf6 23. Kd3 Rxe4. White's best defence now is 22. Qd4; (5) Rxd7
is countered by 35. ... c2 36. Rc7 Nc6.
15. (1) White gains the decisive advantage by playing 19. a5!
Nxd6 20. ed Bxa5 21. Ne5 Qe8 22. d7; (2) In this case, White
would also win, e. g., 22. Rel Kf6 23. Bxe7+ Nxe724. Qf3+ Ke6
25. Nf7+ Kd7 26. Qg4+ Kc7 27. Qf4+ Kd7 28. Qd6+ Kc8 29.
Rxe7 (analysis by G. Serzhanov).
16. (1) 14. ... Re8 would offer him more chances; (2) On 22.
... Nc6 White has the strong continuation 23. Bh6, e. g., 23. ...
Rf7 24. fg hg 25. Rxf7 Qxf7 26. Rfl Qh7 27. Bg5 Rf8 28. Bf6!; (3)
In this case, 28. Rel is very strong.
17. (1) The line 6. ... d6 7. d4 Bb6! is quite reliable; (2)
Again, 7. ... d6 would be better; (3) the idea behind the move is
to hamper the development of Black's Q-side forces; (4) He
ought to have replied 14. ... Qf6, with a sturdy defence.
18. (1) "Black of his own free will give back his extra Pawn,
and, moreover, he will not be able to castle. It is true that he has
the Bishop-pair and may use open lines on the K-side. Up to a
certain time White will have found it rather difficult to exploit
Black's weaknesses, but White is bound to succeed, for these
weaknesses are permanent" (Ragozin); (2) A good alternative is
15. 0—0—0! For example, 15. ... Bc5 16. Qb2 c6 17. Bb3 a5 18.
g3 Qf6 19. e5!; (3) Here, again, 17. 0—0—0! is strong,
e. g., 17. ... d4 18. Nf3 dc 19. Nxe5 cb+ 20. Kxb2 with a great ad-
vantage to White; (4) Ragozin estimates that 27. c4! a6 28. Nf3
Qf5 29. Rxd6+! Kxd6 30. Qd4+ would be the strongest; (5) 33.
182
... Qc7 would be the best defence; (6) If 36. ... Bxf4, then 37.
Re7+ Kc6 38. Re6+ Kc5 39. R d 5 + , etc.
19. (1) The line 6. Bb2 Ng6 7. Nbd2 would offer White good
attacking chances; (2) 8. Nbd2 is right here.
20. (1) Correct is 6. ... Bxf3 7. Nxf3 Bb4+ 8. Bd2 Bc5 (also
playable is 8. ... Qe7) 9. a3 a5 with complicated play; (2) After
10. Qxb7 Rb8 11. Qa6 Rb6 12. Qa8+ Rb8 the game would be
drawn; (3) In the event of 12. Nbxd4, Black may counter with 12.
... Ra5 13. Qxb7 Nxd4 14. Qb8+ Nc8 15. Nxd4 Be4 16. Nf3 Bxf3
17. ef Rxe5+ 18. Be3 Bc5, and his attack is quite dangerous; (4)
After 13. Qxb7? Qxb7 14. Nxb7 Nc8 the White Knight would be
trapped on b7.
21. (1) Black should have replied 9. ... 0—0; (2) On 13. ...
Qxal, 14. Bxc5 is strong and on 13. ... Rf8, the variation 14. Bxf8
Kxf8 15. Qf4+ Kg8 16. Ne7+ Kh8 17. Qf7 would decide the out-
come of the game.
22. (1) He should have exchanged on f3, because the Knight
on e5 occupies an unstable position; (2) In reply to 13. Qxd4?
Black would play 13. ... Nc5 with a good game; (3) On 23. ... g6,
there would follow 24. gf Ne8 25. Re7! Nxf6 26. Qxf6 27. Bxf6,
and Black has no satisfactory defence to White's threats.
23. (1) White's best move is 8. e3; (2) "Imperative is 12. Nd5
and if 12. ... Qg6, then 13. Ne2, followed by Nf4 or N2c3, and
White may still defend himself' (Alekhine); (3) "15. ba Qc3+ 16.
Kbl Rd8 17. Qxd8 Nxd8, threatening both 18. ... Bxdl and 18. ...
Bf5; or 15. Rd2 Bxb2+ 16. Rxb2 Qc3+ 17. Kbl Q e l + 18. Kc2
Rd8 and Black wins" (Alekhine); (4) "If 17. ... Rd8, then 18.
Nh3! Qf6, with chances to save himself" (Alekhine); (5) 25. b4
Rc3+ 26. Kb2 Qcl mate; 25. Kb4 Qd2 26. Kxc5 b6+ 27. Kb5
Qa5 mate.
