Hi! >Crafty >Pepito >Amy >ExChess >Arasan > >Lots more besides these, of course. OK, I learn Crafty sources very good. With Pepito I have troubles because I don't know Spanish ((: SmarThink is a bitboard engine. But it not uses rotated bitboards. Instead of doing this I have a little different but not much faster approach. >Some typical tricks: >Have a table of precomputed distances to find out if the king can catch the > pawn or not. I have the same tables and also integrated tables for K+P vs P. But I use this tables in pure pawn endings. Crafty also not uses "catch" tables in rook endings. It's surprize for me because I think that, potentially, clever using of this tables must be a good advantage for fine evaluation. But I may be wrong because now I'm not tried to do it... A few words about Ruffian. Ruffian is very good in endgames. But I think that Ruffian's strength in endgames based not on lot of knowledge but on very clever pruning/(or extending?) techiques. Sincerelly yours, Sergei
