You can play chess with computer, using a java program that I have developed. The chess engine is anything but serious ; it does not support promotion, castling, en passant, but it can be seen as a basic "expert system" program. The source code is here.

Note, that there are no options in the program as all of them have been hardwired in the source. You take the white side, and in order to move, you just click the piece and then the position to move to.
