In this position, from an online Chess960 blitz game, it's white to play and, indeed, win. That's not the puzzle though: with five white pieces pointing menacingly at the black king, some kind of breakthrough is obviously on the cards. And indeed, with 11.Rxh6 gxh6? 12.Nxe7+, I forced my opponent's resignation.
Instead, the puzzle is how does white win most accurately after 11. Rxh6 Be5! - the most defiant defence? If you want a clue (and an incentive) the !! comes on move 14. And frankly, I'm not sure two exclamation marks are quite enough . . .
PS. It being Chess960, I ought point out that whilst black has already castled, white has yet to do so (and indeed in the diagram position above, has not moved either king or rooks.)
