It’s Your Move: daily chess puzzle # 92

White to play and win

Lengyel v Pogats, Budapest 1964

Solution

A nice variation on a stand theme: the natural aim is to trap Black’s queen, which is in a bit of a net, but soon entrapment is seen not to be possible. But then the jump biff Rf1-f7 is seen, and 1 Bg4! Ng4[] 2 Rf7+

with mate to follow. If 2…Kf7 (2…Kg8 3 Qh7 mate) 3 Qh7+ and if 3…Ke8, 4 Qf8 mate, or if 3…Kf6, the optically nice 4 Be7+ is mate.
