mpchess
simple chess game written in C
Sour*eforge.net has become inaccesible to me because of Cl*udflare. The latest versions of the programs will be on my site: https://matei.one/. Simple chess game for people who want to play chess but don't want to take it seriously. Written in C, using SDL 1.2 or SDL 2 for graphics. Interface inspired from old chess game for ZX Spectrum. The computer searches (L+2)/2 moves ahead (assuming that a move means that both sides move a piece), where L is the difficulty level. Positions are evaluated only by adding the values of the pieces left on the board. Any factors related to where the pieces are, such as mobility, doubled pawns, isolated pawns etc. are not considered. To add variety to the game, possible moves are randomly shuffled before every search. -

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. Thereby, if you try a gambit yourself, the program might try to a counter-gambit (or sometimes an unconventional line). It will play weak against other engines, and it not meant as to play very strong/perfectly, but for human opponents, the gambit lines will most often result in entertaining -not boring- games, and require quite some concentration to avoid tactical mistakes. -
