I just read that Genius 6.5 & CM7000 found a M10 in ~15 seconds on a p2/400, and there also is a mate in 9 (proven by Chest). Ok, I have 2 questions for you, but if you don't want to answer them I understand completely, just can't resist. :) 1. Is your QSearch relatively simple like mine, or do you extend/look at check(evasion)s etc in there like Ed seems to do? 2. I'm going to convert my movegen to 16x12 any day now (like you have if I remember correctly). One thing I don't like is that some arrays get twice as big, like the history one and the ones for piece-hash-value-lookups. It's possible to prevent that by calculation, but do you have any recommendations? Wish we had palmtrees over here in Amsterdam :) Groetjes, Paul
