Puzzle

I came across this puzzle the other day.





White to play and win.











1. Rh5! is decisive. (1. Qxc3 does nothing and leaves white a pawn down).












After the forced 1... gxh5, black's king is horribly exposed.











2. Rg5+! is the winning move.













As 2... Kh8 (forced) is met with 3. Qh6#.
