API Feature Request: Send full FEN on all /api/stream/game/{id} events #12357
Description
This is an API feature request to send the full FEN on all /api/stream/game/{id} events. This would be beneficial specifically for Crazyhouse and Three-Check as the FEN contains unique parts (such as the crazyhouse pocket and check counter).
Currently, the full FEN is only sent in the first message. Follow up messages only contain the board FEN.
Example:
{"id":"TQUh1YtP","variant":{"key":"threeCheck","name":"Three-check","short":"3check"},"speed":"bullet","perf":"threeCheck","rated":true,"fen":"2k3r1/p1pq1p1N/1p2p2P/3pP2R/3P1Q2/2P4K/P1P2P1r/5R2 w - - 3 27 +0+3","player":"white","turns":52,"startedAtTurn":0,"source":"friend","status":{"id":60,"name":"variantEnd"},"createdAt":1676145078042,"winner":"black","lastMove":"g2h2","check":"h3","drawOffers":[52],"players":{"white":{"user":{"name":"Frido1802","id":"frido1802"},"rating":1856,"ratingDiff":-44,"provisional":true},"black":{"user":{"name":"Professor_Eisenstahl","id":"professor_eisenstahl"},"rating":1890,"ratingDiff":26}}}
...
{"fen":"2k3r1/p1pq1p1N/1p2p2P/3pP2R/3P1Q2/2P5/P1P2PrK/5R2 w","lm":"g6g2","wc":2,"bc":14}
{"fen":"2k3r1/p1pq1p1N/1p2p2P/3pP2R/3P1Q2/2P4K/P1P2Pr1/5R2 b","lm":"h2h3","wc":1,"bc":14}
{"fen":"2k3r1/p1pq1p1N/1p2p2P/3pP2R/3P1Q2/2P4K/P1P2P1r/5R2 w","lm":"g2h2","wc":1,"bc":11}
I'm using the endpoint above in an application I'm working on which has the ability to watch TV games. Providing the full FEN would allow for showing the Crazyhouse pocket and check count.
