White to play and win

Solution

Purdy's examine all biffs mantra means that 1 Be6! has to be looked at. The Pd7 is tied to defending the Nc6, which drops off if the B is taken, so 1…Re8 2 Rf7 Qf7 3 Bf7 Re4 4 Re4 is all that really needs to be calculated- back rank mate.

Houdini also tells me that 1 Qf3! wins.
