Test your chess: daily chess puzzle # 190

White to play and win

M Rubery v JL Gluckman 1988

Solution

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.
