Why? > The Chessmaster 2000 is available for 8 and 16 bit machines. This program running on an Atari 800 would certainly not rate as high as when running on a Mack or Atari ST. Also a provisional rating is by no means an offical measure of a chess players' ability. A provisional rating in simple terms means that not enough games have been played to represent the true strength of the player. The name of this program is extremely misleading. The word 'Chessmaster' in no way or stretch of the imagination should be intepreted as meaning this program plays master rated chess. The number '2000' also does not mean it plays 2000 rated chess. There is only one way to determine how good it is, and that is to have it officially rated by the USCF. I believe that only two consumer chess computers have official USCF ratings and they are: Par Excellence at 2100 and the Super Constellation at 2017. Most chess programs have never been officially rated for one reason or the other. But most chess programmers have some rather wild claims as to the ability of their programs. To my knowledge, there is only one formula used by the USCF for determining the rating of a chess player, be they human or machine. ray
