It’s Your Move: daily chess puzzle # 40

White to play and win

Rusakov v Kalinkin, RSFSR, 1963

Solution

Black is well and truly trussed up, allowing White the time for 'revolution and evolution', to use a phrase from Jacob Aagaard's books on attacking.

1 Qf7+! Kf7[] 2 Rf7 and if 2…Kf7, 3 Rf1+ and 4 Rf8 mate, or if 2…Qd6, the 'evolution' 3 Rdf1 followed by Rf8+ Qf8 Rf8 mate.

I always write my blog posting first, then enter the position into Stockfish on my iPad, so as to be able to include the diagrams. Here, Stockfish surprised me with the even better 2 Bg8! and mate next move. Pretty.
