Daily chess puzzle: Check Mate #437

Another puzzle from Dragoslav Andric’s 1981 book “Matni Udar”.  
White to play and mate Black. 

Zimmerman v Hübner, Koblenz 1977
Solution 
The first move is easy, 1 Qe5+, since the Nd7 is tied to preventing Rd8 mate. 
Then 1….Qe6 when after a little thinking, 2 Nf6+! deflects the g pawn and is followed by 3 Qe6+ and 4 Bh5mate.
