    Try Fairy Stockfish. Not as strong as regular stockfish but still should be more than enough.
  • The difficulty of computer duck chess.
    1 project | /r/chess | 12 Dec 2022
    I actually already implemented it in Fairy-Stockfish, although as a separate branch: https://github.com/ianfab/Fairy-Stockfish/tree/duck. As we currently still reuse the chess evaluation until we have a first NN(UE) it isn't on top human level yet, but move ordering already is decent, so once we have a proper evaluation it should do much better.
  • Introducing... CHESS.SEX
    1 project | /r/AnarchyChess | 7 Dec 2022
    implement your favorite Anarchy Chess rules with fairy-stockfish (https://github.com/ianfab/Fairy-Stockfish), which lichess already uses for the variants it hosts, so it should be easy™ to make your cloned lichess accept it
  • Did someone make a Chess Bot Analysis Check for Duck Chess?

    Oh, apparently an experimental fork of fairy-stockfish with duck chess support was published yesterday! https://github.com/ianfab/Fairy-Stockfish/tree/duck

  • Is Minishogi solved?
    1 project | /r/shogi | 3 Aug 2022
    To my knowledge it isn't. Some of the small-sized shogi variants, like Dobutsu, Micro, or Kyoto shogi, can either be (practically) weakly solved using engine search or even strongly using tablebases in the case of dobutsu shogi. However, for minishogi neither of those have yielded a definitive result yet to my knowledge. Nevertheless, deep engine searches and games from high level engines strongly indicate that gote, i.e., the second player, wins with perfect play.
  • How does the Fairy Chess YouTube channel make custom chess games and make Stockfish fight? How can I do that?

    But, if you have a variant which the free Fairy Stockfish or ChessV (Alt link) can not play, Zillions can probably implement it fairly easily. Just this year, I created a Chess variant using an unusual tiling of squares and triangles. The only engine which can play this variant is Zillions.

  • Code works on Mac but gives floating-point exception on Windows
    1 project | /r/Cplusplus | 14 Jan 2022
    Hi friends - I'm trying to compile my chess engine for Windows, and my makefile does compile the EXE (using Cygwin/MinGW) but when I try to run it, I get a floating-point exception. I don't think this is a division-by-zero error since the code works on my Mac - can anyone please help? Thank you :)

    Hi there :) so I'm trying to compile my chess engine for windows. My 'make' command works perfectly on Mac, but trying to compile on Windows is an absolute nightmare... Would anyone more familiar with Windows please take a look at this & help out? I'd really appreciate it :)
