White to play and win
M Rubery v JL Gluckman 1988
Fairly simple today. Following two of Purdy’s maxims, first of all ignore the threat, and secondly examine all biffs, leads to 1 Bh6+! when it is all over.
If the B is captured, then 2 Qf6+ Kh5 3 g4 mate; if 1…Kh8, 2 Qf6+ Kg8 3 Qg7 mate; and if 1…Kg8, 2 Rg3+ Kh8 3 Qf6 mate.
