Another puzzle from Dragoslav Andric’s 1981 book “Matni Udar”.
Black to play and mate White
Gerasimov v Smyslov, Moscow 1935
Solution
This has shades of the famous Rubinstein ending vs Rotlewi : 1….Rd3! 2 Qb6 Rh3!
3 Bd4 (3 Qc6 Bh2+ 4 Kh1[] Nf2 mate, so the B must defend f2) Bh2+ 4 Kh1 Be5+ 0-1, because the Bh2+ check and discovery will repeat, next being Bc7 and then Bb6.
The game, which was a casual game, is deeply annotated in Megabase. Smyslov crunched the Colle in convincing style.

I can’t get the FEN to work. Position is right, the last little bit must be wrong.
Brilliant, isn’t it?
