Maybe for curious I must give some numbers that indicate relationship between logic structure and NPS rate. When I tryed chess logic on AMD 400Mhz, I disconnected alpha-beta, numbers went sometime 800000nps. The same game but alpha-beta already in, game reach in best moments 300000 nps. Average NPS is 208000. Leonid.
