I think it quite possible Arasan misplayed this at some point, but I'm not sure this is the point. Arasan likes Ke3 basically forever: it's score drops a bit if I let it search long, but it still thinks it is well ahead. I fed the same position to Crafty with 5-man TBs and let it think for 40 minutes. Crafty likes Nh3 here. It failed low near the end of the search with a score of +1.30 (quite a bit lower than what Arasan is getting), but didn't select another move. Crafty searched over 2 billion nodes here! Analyzing the endgame from this point forward would be interesting, and might point up an error. --Jon
