Daily chess puzzle: Check Mate #239

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

Black to play and mate White

Letelier v Fischer, Leipzig 1960

Solution

A position I knew, I think from my teenage years.

First, a sac and a double exchange on e3: Re3/Re3/Re3/Ke3

and now the ‘point’, 3…Qf4+!, and White’s position collapses after 4 Ke2 or Kf2, and it is mate after 4 Kf4 Bh6mate.

White resigned. Had he decided to continue, say with 4Kf2, the Ns would have invaded and overrun: 4…Ng4+ 5 Kg2 Ne3+ 6 Kf2 Nd4 7 Qh1 Ng4+ picks up the Bf3.
