Cordingley puzzle 47

White to play and win

Solution

For a while, this stumped me. I tried things like 1 Nf7+, 1 Nf6, even 1 Qh5, then thought for a moment that, in a game, I might just play 1 c3: and felt I had no ideas.

I then looked for LPDO, noting the Queen is defended, but that the Be7 is not. Then, the solution came to me: 1 Nd7+, 1…Rd7 (forced) 2 Nf6+ gf 3 Bf6+! followed by Qh5 or Qe4, mating.
