It took me well over a year to get the pawn-hashing in, let alone extended futility pruning. I don't use that at all, if you're talking about the DarkThought stuff.

Do you also use rotated bitboards and book learning? :) I did notice that you're king safety was weak, I was able to get in there pretty easy. But otherwise it played very well. Will
