    UCI chess engine

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

    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).

    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.... ).
