From a game won by Bondarevsky years ago. 1.Nxh6+ The other knight check doesn’t work 1.Nf6+ Kh8 and there is no continuation of the attack. It worked only if Black cooperated by taking with the pawn. 1...gxf6 2.Qg4+ Ng6 3.Bxg6 fxg6 4.Qxg6+ Kh8 5.Qxh6+ Kg8 6.Qg6+ Kh8 7.g4 e5 8.Rd3 Bxg4 9.Rg1 and wins. 1...gxh6 if 1...Kh8 2.Nxf7+ Kg8 3.Bh7# 2.Qxh6 Ng6 3.Bxg6 fxg6 4.Qxg6+ Kh8 5.Qh6+ Kg8 6.Rd3 Bxh4 7.Qg6+ Kh8 8.Rg3! and Black Resigned as if Bxg3, then hxg3 is mate after the black queen gives herself up.
