At this page you see two chess engines play chess against each other. The pieces are art pieces of Dutch artist Arthur Mulder, an artist based in Rotterdam - Hoek van Holland. It is however possible to adapt pieces yourself, moreover the visitor is encouraged to change the representation of the chess game, such that this page be dynamic.
The chess engine is written in Javascript. Before making a move, the algorithm checks all possible valid moves and chooses one at random, giving all moves an equal probability. At the end of the game, they start playing again.
