Daily chess puzzle: Check Mate #144

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

Black to play and mate White

Botvinnik v Stahlberg, Moscow 1940

Solution

Surprisingly, I can’t find this game: odd, given who the players are.

Not too hard today, because various sensible moves win. 1…Rg2 is given by Fritz as -12; 1…d4 -25; but 1…Rh3+ is mate in 6, after 2 gh d4!
