Cordingley puzzle 148 #chess

White to play and win

Solution

The first move is easy, though in fact Houdini tells me the position can be improved even further by first playing 1a3 Ba5; but 1 Ng5 is clearly strong: all that is needed is to compute the precise follow up. I quickly saw the idea of Bg7+! Qg6+ Bg8, but prefaced it by Rh3: the engine tells me that it is better just to play Bg7+, as in the game, with mate in seven.

A nice puzzle.
