Is chess a sport? Officially, yes. Did the British invent it, Mr Cameron? Categorically, no. The Persians shaped the game we recognise today from its ancient Indian roots, with the word rook thought to have derived from the Persian rukh, meaning chariot. The Moors caught the bug in Spain in the 10th century. In fact there’s really not much cool Britannia about it, though of course the Russians are not too bad at all at it.
