    Stockfish

    Stockfish

    UCI chess engine

    Stockfish is a free, powerful UCI chess engine derived from Glaurung 2.1.

Read the documentation for your GUI of choice for information about how to use Stockfish with it.

    AlphaZero.jl

    AlphaZero.jl

    A generic, simple and fast implementation of Deepmind's AlphaZero

    Beyond its much publicized success in attaining superhuman level at games such as Chess and Go, DeepMind's AlphaZero algorithm illustrates a more general methodology of combining learning and search to explore large combinatorial spaces effectively. We believe that this methodology can have exciting applications in many different research areas. Because AlphaZero is resource-hungry, successful open-source implementations (such as Leela Zero) are written in low-level languages (such as C++) and optimized for highly distributed computing environments. ...

    Chess-gambiteer

    Chess-gambiteer

    Chess training program playing gambits

    Program to train against gambit play (*) with the computer, with a strength adjustable chess engine (Danasah, currently set at approx 1400 EL0 when playing against it). Also included now are two options to watch an engine e.g. the 'aggressive' Patricia5 (with gambits) play against another engine (eg IM level). The engine gambit books are made in such a way that 1) real lousy gambits are not played, and 2) the book is choosing a gambit line as often as possible, so for Black it might go for e.g. a Benko gambit or so and if you let it play with White, a lot of 1.e4 gambits can be played. ...

    Fair-chess

    Fair-chess

    A new -better- chess variant , *Fair-Chess* ! (also with handicaps)

    A new -(and much better) sort of Chess game , *Fair-Chess* ! Being interested in chess for two decades now, i designed a chess variant in which the intrinsic White advantage is compensated by removing the f2 and c7 pawns (calibrated by engine analysis). Also, in such a way detailed knowledge of opening theory is not important anymore (but it still looks more like normal chess than Chess960, also called 'Freestyle' nowadays.... ).
