It’s Your Move: daily chess puzzle #341

Black to play and win

Vaganian – Planinc, Hastings 1974

Solution

In a game, I am not sure what I would have played, but since it is a puzzle -and since I vaguely recall the denouement – I probably saw the game in BCM in my teens- 1..Nc2+ 2 Kd2[] (2 Ken?? Bg4+ discovers on the Qe8) 2…Bf5

3 Qa8 Qd6+ 4 Kc1 4…Na1!

and if 5 Qb7 then 5…Qc7+ is a nice deflection (6 Qc7 Nb3 mate).
