The analysis is bogus, the line given is an easy draw, not a win >for black. I suggest you look again. This is _not_ an "easy" draw. This is an easy mate in 3 for black... Not sure who has the bug, but it isn't me. :) I spotted this easily as a human, so even though Crafty doesn't see it on the end of that shallow search, -3.5 is certainly good enough to convince it that black is better. _much_ better.. BTW, after Qxg7, Kb6 and white can't avoid Qxe4#. He can put it off by a spite check tossing his queen, but that's it... > >>So Crafty sees the mess within a second. > >Hardly...it has other bugs :) > >-- >GCP
