Daily chess puzzle: Check Mate #322

Another puzzle from Dragoslav Andric’s 1981 book “Matni Udar”.

White to play and mate Black

Marmagen v Cane, correspondence 1966

Solution

1 Qg6+! is clearly the move, though 1 Nh5 is simpler and winning. But after 1.Qg6+. if the Q is captured, 1…Kg6, then 2 Ne5++  Kf6[]

I found the longer mate, 3 Bg5+ which brings the K forward, but in this correpondence game White found the quicker 3 Rf2+! Ke7 (3…Ke5 4 Rf5 mate) 4 Nc6+! Qc6 5 Bg5 mate.
