And it looks like it may win. Is 30 Ng5 losing? Move 36 g5 >-- seems to win the game. Things are much simpler. I believe white wins! Here is why. 30. Ng5! Kc5(?) 31. Nf7! +- for example 31. ... Bg3 lets the white king to c2 and then the game is over. 30. ... Kc5 is bad because the king can no longer stop the pawn on d5! However a computer chess program will very likely go for 31. Nxh7 ... This seems like a good test position! Hristo
