A couple of months ago, someone (chessfun?) played a long series of matches played between Fritz and Crafty. Several different time control were used, with each match played first on a single computer, and then on two computers. As I recall, the results were practically identical over a large number of games. Crafty seemed to do better as the time controls got longer, but that's another issue. Maybe that person could post the results again? --Peter
