Daily chess puzzle: Check Mate #321

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

White to play and mate Black

Peretz v Srepanz, Tel Aviv 1966

Solution

A nice exploitation: 1 Qd6! threatens 2 Ra7+ and 3 Qb8 mate, so 1..Bd7, but that interferes with the Qf7’s sight of a7, so a double rook sacrifice followed by Qa3+ and Qa6 mate.
