My search is selective only because of null-move. I believe this is also the case with Fritz. With null move on, my program searches 634k NPS. (BK, short searches) With null move off, it searches 655k NPS. The difference is 3.3%. Basically, I wouldn't worry how much faster Fritz is without null move, for three reasons: 1) The difference is probably pretty insignificant 2) You'd never want to run Fritz without null move in real-world situations 3) You didn't write Fritz -Tom
