Daily chess puzzle: Check Mate #73

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

White to play and mate Black

Alekhine v Feldt, Tarnopolj 1916

Solution

1 Nf7! Kf7 (1..Qc8 and Black loses prosaically) 2 Qe6+! Kg6 3 g4 1-0 There are alternative ways to win: 3 Qf5+, for instance, and Black can also defend, but it still hopelessly lost, by 2…Kf8.
