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.

Nakamura appears to be struggling as his rook and knight are both threatened and he must lose material. 25 … g5! This powerful strategic move cements his knight on f4 and generates excellent compensation for the exchange. 26 Nxe8 Rxe8 27 Qg3 h6 28 Rd2 Ne5 29 Rad1 Nc4 30 Rd7 Qxb2 31 Rf1 Ne5 The black knights are utterly dominant. 32 Rd6 Neg6 33 Rf2 Qe5 34 Rd7 Rc8 35 Rxb7 h5 36 Kh1 Rc3 37 Rf3 Rc2 38 Rf2 Rc3 39 Rf3 h4 40 Qe1 Rc2 White resigns
