  It took me a while to figure out why cfdincle’s solution is a win. Got there in the end.

  First of all, 3. … Ne7 4. dxe7 and 3. … Nf6 4. Kxf6 are straightforward white wins.

  After 3. … Nh6:

  4. Kxh6 Kg8
  5. Kg6 Kf8 (5. … Kh8? 6. Kf7!)
  6. Kf6 Ke8 (again, 5. … Kg8? Ke7!)
  7. Kg7! Kd8
  8. Kf7 Kc8
  9. Ke7 and black’s pawn is toast, plus no way black can stop the white pawn’s promotion.
