Daily chess puzzle: Check Mate #476

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

Black to play and mate White

Huss v Korchnoi, Biel 1979

Solution

Like yesterday’s puzzle, this took me a while, but was satisfying to solve.

1…Ra1+ 2 Rb1 (2 Ne1 Ne4) Qe4! is a double attack, and ‘the point’. The rest is just checking how to conclude the game.

3 Ra1 Qe2+ 4 Kg1 Ne4 and 1-0; if 5 Rf1 as played, 5…Bd4 concludes; or 5 Qa7, 5…Ba1.
