PostPost subject: Position crafty and stockfish both badly mis-evaluate    Posted: Thu Jul 29, 2010 8:40 pm Reply to topic Reply with quote

I tried this position with Crafty-23.2 and Stockfish 1.8 and they both give scores > 8 after analyzing for more than 1 minute, while the position is a tablebase draw. These seem like remarkably optimistic evaluations with no win in sight.
[D]2k5/8/Pp1K4/8/7B/8/P7/8 w - - 0 1 bm a4; id "Fine 149 draw";
