Test your chess: Reitstein problem 184

White to play and win

LR Reitstein v A de Oliveira Dias 1960

Solution

1 Bf4+! is more or less the natural first try, preventing Kd6 (so better than 1 Qf5+). If the bishop is taken, then 2 Qf5 is mate; 2…Kd4, 3 Qd3 mate, so the only move is 2…Ke4 when 3 Qf3+ Kf5 (3…Kd4 4 Qd3 mate) and 4 Bc7 dis ch and the game is over.
