Okay, now here's something I just don't understand. On my slow 240 MHz PowerBook, the freeware programs MacChess and Sigma Chess 5.1 reach 120-150,000 nps in the middlegame. MacCrafty 17.12 does around 20-30,000 nps. My own program, inferior to all three, does about 20-25,000 nps. Why such a great difference in speed? I don't even see how taking knowledge out would manage it (not that I want to do that). Just for a laugh I tried material only evaluation, and got only about 45,000 nps. It seems impossible to me even to reach 80,000 nps, let alone higher. Can anyone please explain the vast difference in speed between all these programs? I trust that my program is not wasting a vast amount of its time, although it's surely not optimised. Cheers, Mike.
