Daily chess puzzle: Check Mate #491

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

White to play and mate Black

Szilagyi v Busa, correspondence, Hungary 1980

Solution

This is very similar to ‘one I have seen earlier’, and the motif is the same: clear the d file so that Rd8 mate can be played, or clear the e line instead. 
So 1 Nc7+! 

Qc7[] 2 Ne6!

2…Qe5

3Nc7+! 

Qc7 4 Qe2+! Ne5 5 Qe5+! Qe5 6 Rd8 mate.
