Even with PVS, you will reduce your node count if you decrease the resolution of your evaluation function. The reason is that you will get a bigger number of beta cutoffs. Consider the extreme case of having an evaluation function which always returns 0. You automatically get perfect move ordering, and you will search really small trees. Your eval will also be very cheap to compute. On the other hand, it could hurt the engine's positional play a bit. :-) Tord
