Colossus Chess X

Colossus Chess X is the first 16-bit adaptation of the chess games series by Martin P. Bryant.

This fully-fledged program understands all the rules of chess, including underpromotion, the fifty move rule and draws by repetition; it can achieve the king-bishop-knight mate. The new features are a modifiable opening book of 11000 moves, the program also learns new lines of play from playing experience. You can also play against the clock, try a blindfold mode or use the program to solve mating problems.

Apart from the standard 2D board there's a 3D one, which can be freely rotated. Four graphical chess piece sets are available, as well as music & speech, and a demonstration mode.
