It’s Your Move: daily chess puzzle #276
White to play and win
Gufeld v Ozsvath, Debrecen 1970
Solution
Not too hard: 1 Rh8+ has to be considered, and after 1…Kh8[] 2 Qh6+ Kg8[] 3 e6 is natural and a quick check shows it wins: Rh1 and Qh7 mate follows.

I can’t argue with the winning line that you give, but do solvers score any points here for 1 g4 ? If the f5 bishop moves, then Rxh8 followed by Qh6 is very simple. Perhaps 1 … g5 would survive for a while, but it seems much better for White after 2 Rxh8+ Kxh8 3 gxf5.
