Test your chess: Reitstein problem 36

White to play and win

D Isaacson v BP Donnelly 1967

Solution

The first move is easy, 1 Rf6!. Taking with the pawn loses to Qg6+-Qh7 mate; taking with the queen struggles on but still loses after 1…Qf6 2 Rf6 Rf6 3 Qe8+ Rf8[] 4 Bc4+ picking up the bishop after 4…d5 5 Bd5+ Be6 6 Be6+: game over. The nicest one is 1…Rf6 2 Qe8+! showing that the Rf8 was tied to defending e8.
