Daily chess puzzle: Check Mate #312

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

White to play and mate Black

Kinnmark v Olivera, Havana 1966

Solution

1Bb6! to deflect the black queen from looking at f7. Black can even continue the game a piece down, or if 1…Qb6 then 2 Nh6+ mates. The nicest line is 2…Kh8 3 Nf7+ Kg8[] 4 Ne5+! with the idea of 5 Ng6 mate.

Perhaps Black’s best line is 1…Ng5, forcing 2 Qe3, when 2….Nh3+ at least picks up a pawn for Black: but +- anyway.
