Easy Endgame Puzzle

White's about to promote - can you save the game?

2. h8=Q is a mistake from white -- far better is 2. Bxa2+.

I'm not sure the game can be saved.

 Bxa2+ is better, but even if white had played it black would have a win. Black play Rxa2+, 3. Kb1 is forced. After that Black has 3. Rh2! which threatens mate. White has to play 4. Kc1 and black wins the outside passed pawn with the obvious 4... Rxh7. Black is up 3 pawns after that, and has an endgame in which white may as well resign. Although, the game did have "??" after h8=Q, so texaspete surely knows that this is a blunder.

Spot on oinquarki - I thought h8=Q illustrated the puzzle better.

Whites best moves are in the variation in the move list - and they are as you say.
