What you said is true also for my program but only for one ply. In all others all moves that are generated are completely verified and put in special order. When I tried to generate 2000000 times all legal moves I found that their number was very low compared with what others folk said. On AMD 400Mz it was around 1660000 moves in one second. Very far from 7000000 or 8000000 NPS. Leonid.
