If it doesn't win, then it's a draw or loss, right? Are we talking long-term or for the current position. When I first looked at it, I thought "I don't see any reason that Nxh3 wins for black here..." And that was my original comment. Stuart found a mate that wasn't there after Nxh3 Kxh3, and then for fun I decided to analyze it a bit for myself and didn't see anything convincing. And my general rule is that if I toss a piece (Nxh3) I need to see _something_ concrete to play that against a computer, as otherwise it will probably turn from an interesting attacking position to a lost position, quickly. So while black may well win, I was immediately suspicious of a nearly +2 eval for black, in the absence of anything concrete... > >Regards >Dave > >Crafty said it was a draw as did a >>couple of other programs. I just don't see a win yet, myself. nor a loss...
