White to play and win

P Künne v C Meiboom 1983

Solution

This flummoxed me for a while. I made the mistake of going on the wrong motif, thinking the black, queen was in a net, and trying to win it by 1 Nb5? Qd2 2 Qf3 with some idea of a follow up. There is none: it is equal.

Eventually I took a step back and examined all biffs. I then saw 1 Rf7! or 1 Nf7+!, preferring the former, which wins a pawn. If black takes, then the floodgates are opened: Rb8+, Qg4+, dependent on what black does, and black's king is mated. The final diagram below is typical of what happens if exchanges happen on f7.
