What do you expect 2 plies to do to crafty's rating? Second question: 6-4 suggests a very _small_ difference in Elo rating. Do you _really_ think Crafty is so far behind that 2 plies won't make a difference? Just flip over to ICC and watch a while... And I _never_ have a 10:1 speed advantage on ICC...
