Well, I can't argue with you there. But just because The King doesn't find one (or two) sacs doesn't mean that those sacs are necessarily sound. As I pointed out in my follow-up, apparently this jury is still out on this move. All I was saying was that there is possibly a way that Black could have "mustered a defense", starting with 16...g6 instead of 16...f5. jm
