It’s Your Move: daily chess puzzle # 69

White to play and win

Kadrev v Vasiukov, Moscow 1964

Solution

Not too hard today, but some calculation needed, noting that Black threatens something like …Bb4+ or …Bd3, in one order or the other. But 1 f7+ (examine all biffs) forces 1…Rf7 (else 2 Nd6 and either the f or h pawn promotes) when 2 h7+ (examine all biffs again) overloads the King. The King is tied to the Rf7 and also the h8 square, so 1-0.
