Daily chess puzzle: Check Mate #294

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

White to play and mate Black

Keres v Bronstein,  Zurich 1965

Strangely, this game isn’t in Megabase: or at least I couldn’t find it.

Solution

I chose 1…Nc2!, which Komodo gives as -3.5: If 2 Rb1 then 2..Rab8 3 Qd5 Rb4+! is the “point”.

But Bronstein played 1..Qb6! assessed as -15: same idea, after the Qs are exchanged, Nc2+ forks the king and LPDO Ra1.
