Huh, doesn't look like it to me...though I'm not a strong player by any means, so I'm probably missing a lot here. Still, it seems like White's pieces should be a good match against the Black queen.

On a random note, I like the idea of Bh7+ to force Black to exchange off his last piece; though White has to watch out first for Qh5 forking the knights.

A rook and two minors vs. a queen and a pawn -- seems like at this level, there's still some fight left. I think had white played 18. Qxd8 he'd have been in okay shape, up two minors for a pawn and with threats of his own.

Yeah, it looks to me like White's still got some fight left in him.
