White to play and win

Solution

The problem is cooked. I devoted my time to 1 Bh7+ Kh8 2 Nh4, when black's best reply is Nbd7, when maybe white has a slight edge. Instead, in the game white played 1 Nh4, which probably transposes after best play: black's best is 1…Nd7.

As played in the game, white gets an overwhelming edge.
