computer chess championship 2005. It uses the UCI (universal chess
interface), for chess engines as communication protocol. This means
to play against it, you will have to use an UCI capable interface,
like knights. This distribution comes with an opening book of moves
that the engine can use for the first few moves of the game. This
increases performance in the chess games opening.
