Last week puzzle was from the game Vilela – Spiridonov (Varna 1977) where Black won with just one, rather surprising move.

1… Nf6! wins a piece by creating two threats: opening the d-file and closing the long diagonal. After 2. Rxd8+ Nxd8 the twin threats of Qe1+ and Kxg7 will be decisive.

Congratulations to all who solved this correctly.
