Chess Titans on Vista

I played a little while with the chess engine provided by Vista. It's called Chess Titans. The engine is pretty challenging. I managed to beat the first seven levels, make a draw at the 8th level, and get my ass kicked in level 9 and 10. What I didn't like was that it breaks some basic rules of chess.
