I do not think you can just lower the ratings straight >across the board. > Lanny I think that the leader of the ssdf(if it is not for a short period) will always be inferior against computers(unless there is a big difference of more than 100 elo ssdf rating). The best players will always buy the number 1 in the ssdf and prepare against it so programs number 2 and number 3 can get better result against humans because humans are less prepared against them. Fritz is leading the ssdf most of the time in the last years. Some other programs like Junior and tiger and chessmaster could be the leaders only for a short time. This is the reason that people buy more fritz and this is the reason that fritz is inferior against humans(I talked with one of the players in the israeli league and he told me that he prepared against Fritz but did not prepared against other programs).
