Daily chess puzzle: Check Mate #488

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

Christiansen v Cifuentes Malta 1980

Solution 

A nice one today. The main ideas are fairly obvious- a Bh7+, maybe a Qh5, hopefully mating or breaking through on the h file. But how to achieve it?
The diverting move 1 Nd7! is fairly obvious, but Black has several good tries: 1…Qc7, 1…Qf4 and 1…Nf4, as well as the obvious 1…Nd7. 

They are are all met in broadly similar fashion, so I will just give one: 1…Qc7 2 Bh7+! and if 2…Nh7, 3 Qh5 mates.
