'Duell' is a challenging variant of chess, even more abstract than the original. Imagine a chess board, but replace the figures by dice. Instead of moving the dice, they are flipped around the board according to their value, obeying the rules of chess. And, you got it, they change their power as they change the number of pips! This 'Duell' software project allows two players to challenge each other, or a single player to get challenged by the computer. Try it, but don't get yourself frustrated too fast! This software has been created and developed by Roland Studer 1985-2010. That year Roland left us way too young and I decided to keep Roland's work and spirit alive, in accordance with the will of his widow. This SourceForge project shall be alive in memory of Roland. 'Duell' is also known as 'Tactix'. Find a simliar project at <http://sourceforge.net/projects/tactix/>. Find information about the original board game at <http://boardgamegeek.com/boardgame/2409/duell/>.

icsdrone acts as an interface between an ICS (Internet Chess Server) and a chess engine supporting the XBoard/WinBoard protocol. Unlike XBoard/WinBoard it does not use a graphical interface so it is suitable for use on embedded systems. icsdrone was originally developed for FICS (the Free Internet Chess Server) by Henrik Gram but currently ICC (the Internet Chess Club) works as well. Some features - "Daemon mode" (run in background). - Auto reconnection in case of network problems. - Builtin support for using timeseal. - An ICS proxy. When instructed via the "proxy" option, icsdrone acts as a proxy for the ICS it is connected to. This is similar to using xboard with zippy but now the "GUI" (xboard/winboard) can be closed without terminating the engine.
