I just wanted to point out that agressive nullmove pruning will cause Crafty problems at fast time controls, *regardless* of the ponder state. And since this is true, why all the hooplah over pondering, when in fact the time-control has much more influence on Crafty's strength relative to other programs? --Peter >> >> >>>I simply say that to play a match, you play the two opponents at their strongest >>>(and best tested) settings.
