Chess Player 2150 is a chess program which played well against the other chess programs of the day and won the 1989 British Open Personal Computer Chess Championship (according to a post in ST Report International Online Magazine, November 13, 1992, No.8.45). The author was not shy about his program's prowess. Built into the program is a pull-down menu, giving it's performance against Chessmaster 2000, Chessmaster 2100 and Colossus X, in 10 games apiece.
The game was designed to improve as it played, so over time a game that played against good players would be much better than when it first began. Users have the option of saving, so that the gained intelligence isn't lost.
