Nezhmetdinov never became a grandmaster. He was a master from Kazan, a long way from the centre of Soviet chess, and the collection of his best games was printed in his home city four years after he died. Polugaevsky was the coming man, on his way to being one of the strongest players in the world and one of its great opening theorists. Here he chooses a sensible plan, gets exactly the position he was playing for, and is then handed a queen he cannot refuse. What makes the game worth replaying is the note Nezhmetdinov wrote about that moment twenty years later. He had seen the sacrifice five moves before he played it, he could not work the variations out at the board, and he says it was that, having to trust it rather than check it, that made it so hard to decide on.
