  Domdaniel: I don't see a trap: I see all the White pieces on superb squares, so that something has to give in the Black position. The Black Queen and Bishop are effectively stuck protecting one another, so ...Bxh4 is a desperate bid to free them. It loses, because White's Queen, Knight and Rook cooperate beautifully. But something had to give.

Still, I think McNab survived for longer than most of Chuky's opponents. Two cheers for the Rat.
