White to play and win

Kurajica- Utjelky, Wijk aan Zee, 1969

Solution

Black has potent threats down the long diagonal, so White needs something decisive, and both 1 Ne6+ and 1 Ng6+ have to be considered. The former is a blunder, losing to 1…Ne6, so 1 Ng6+!

and then the pretty sequence 1…Kg8 (else the f line is opened pinning the Queen and King) 2 Qe8+ Kh7[] 3 Qh8+! Bh8[] 4 Nf8 mate.
