Daily chess puzzle: Check Mate #477

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

Black to play and mate White

DeCarbonel v Berliner, correspondence 1980

Solution

1…c3 is a natural try:

First of all, one must check if White can capture the LPDO Queen: he can’t.

2 Qd5 cb+ 3 Rb2[] Rf1+ mates.

So the only thing which remains is to see if White has a perpetual or a save: 1 Qe8+ Kh8 2 Qe7+ Bg7 3 bc:

3…Qd6 seals the deal.
