Which came first to the designers of chess: the rules or the metaphor? It feels impossible to prise the system from the story: a military battle between two monarchs, each with perfectly symmetrical assets and equally balanced capabilities. Yet there have been dozens of ‘reskins’ of chess, swapping the kings and their minions for characters from, say, Lord of the Rings, or The Simpsons, or even, bewilderingly, M&M chocolates. Play is the primary way in which every human first tests and explores the world  Sometimes the new metaphor imbues the game with a socio-political frisson. A recent example pitches rockers – white men in leathers holding screaming guitars – against jazz musicians – black men in white suits nursing saxophones.

Even before the 872-day long siege ended, both survivors and onlookers had already begun to refer to Leningrad – formerly and currently known as St Petersburg – as a city of heroes. Tales of bravery and self-sacrifice were enshrined in memorials, histories and memoirs, which between 1945 and 1991 were published in the Soviet Union at an average rate of one per day. But heroism is, of course, only a partial description of life within the starving city where theft, murder, betrayal and a million smaller acts of self-interest were just as prevalent as acts of valour. The idea that Leningrad was a city of heroes was in part a ploy to enable the living to carry on alongside their survivors’ guilt, sometimes inside apartments they had taken from the newly dead.
