Daily chess puzzle: Check Mate #250

Another puzzle from Dragoslav Andric’s 1981 book “Matni Udar”.

White to play and mate Black

Bronstein v Geller, URS Chmpship, Moscow 1961

Solution

I found the win 1 Rf7, which apparently is mate in 7; but missed the prettier move played in the game, 1 Qg6!, which is even faster.

Geller resigned. 1…fg 2 Rg7+ and 3 Ng6 mate.

The game, which is in Megabase, is worth playing through: a 20 move victory by Bronstein in the Nimzo-Indian.
