Luke McShane, England's 12-year-old super-prodigy, notched up his second grandmaster scalp last weekend. Playing for Richmond in the 4 Nations Chess League, he beat Jonathan Levitt with a surprise mating finish in an endgame. Although the end came through a blunder by Levitt, McShane played the whole game with great maturity. When 12-year-olds beat grandmasters, you expect short tactical accidents, not an early queen exchange and delicate manoeuvring.

Black had the advantage after 24...Rxc4, but lost his way after executing the correct plan of b5, a5 and b4. 38...Rcb8 would have been better than 38...Nxb4, and 41...Rb8?? was fatal. He is mated after 42...Kf8 43.Rxf7, or 42...Kg7 43.Rxf7+ Kh6 44.Rh7, or 42...Kh8 43.Rxb6 Rxb6 44.Rxf7 followed by Rh7.
