Is this just like I >read it? Your program see 1083291 nodes/second? Yes it is :-) But my program is not anywhere near a fast searcher really. It's just that it seems to like this position, and with my 920MHz Duron this adds up to a lot of nodes/sec. In normal games it gets anywhere between about 450kNPS and 800kNPS usually. If I run the WAC tests at 5 seconds per position it avaerages about 700kNPS (and solves 288/300). Cheers, Tim. >It is too far from what I can expect from my NPS.
