Daily chess puzzle: Check Mate #69

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

White to play and mate Black

Hartlaub v Testa

Solution

Quite a standard motif: sacing on g7 a couple of times, then on e5, and capped by a nice mate once Black opens the a2-g8 diagonal by playing f7-f6.

1 Rg7+ Kg7 2 Rg1+ Kh8 3 Qe5+! de 4 Be5+ f6 5 Bf6+! Rf6[] 6 Rg8 mate.
