Congratulations to the organisational team of the Isle of Man Masters, which concluded last weekend. They assembled what must have been the strongest ever field for an open tournament in the history of international chess. Magnus Carlsen showed the kind of dominance he can achieve when he moves into overdrive. Leading results were: Carlsen 7½/9, Viswanathan Anand and Hikaru Nakamura both 7, with Michael Adams, Fabiano Caruana and the former world champion Vladimir Kramnik sharing 4th prize.
