I didn't think further to see if SEE >can be done more efficient with Steffan's method. Most likely there won't be a match to NxQ pattern at all, so it would be faster to do 1 check than 8 checks here (ie running all directions in parallel). >Steffan? You wrote someting you name SME? Does it include a SEE? I think so, the idea (or at least my way) is to make a general static evaluation. I posted some positions a week ago or so, the SEE from Crafty doesn't deal with promotions or non-captures. I think it doesn't matter too much with the non-captures, you just want something decent and fast there, SME may be overkill. However I generate promotions along with captures, so I need to sort these along with captures and the promotions may or may not be captures. Promotion to a queen could be a better move than winning a knight, but if the promoted queen is lost instantly winning a knight may be better, so there is a problem with regular SEE. -S. >Alessandro
