Cordingley puzzle 234 supplementary puzzle #chess

White to play and win

If black plays 1…Kg8, how does white win?

Solution

This is the end of the main variation (see my previous blog, on puzzle 234 itself: 3…Re4! 4 Ne4, when 4…Ne5 is equal). If 4…Kg8 then 5 Nf6+!! (Purdy: examine all biffs) and if the knight isn't captured, then the LPDO Bd5 drops off. So 5…gf[] 6 Bf6 and mate follows….the rook lift Rh3 happens if necessary.

Very nice.
