Chess by Leonard Barden
Since Magnus Carlsen became, for a day only, the youngest ever world No1 on the live ratings, the Norwegian 18-year-old's career has, judged by the Olympian standards of Bobby Fischer and Garry Kasparov, gone into something of a stall. Carlsen holds his own in elite tournaments, but the odd moment of teenage carelessness costs him points.
He could have won this week's "chess Wimbledon" at Linares but for falling into a simple drawing trap in the penultimate round. Yet he still finished only half a point behind the winners, and it seems his advance to overtake the world's current top pair, Vishy Anand and Veselin Topalov, is just a question of time. Leading Linares scores were Alex Grischuk and Vasily Ivanchuk 8/14. Carlsen 7.5, Anand 7.
Since Garry Kasparov retired from chess and became a so far unsuccessful Russian politician, the former world champion has frequently kibitzed at major events and has become known as a severe critic of his one-time peers. So the fact that Kasparov described this week's game as "brilliant" – and that against a Sicilian with 11...Re8 which was a favourite line for the all-time No1 – suggests that Carlsen's time will come after another year or two of maturing.
Carlsen's new step on a well-trodden path was 15 fxe5!? which looks harmless but has long-term designs of combining the advance of his queen's side pawn majority (achieved by 20 Nd5) with a latent Rxf6 sacrifice. Black should have exchanged pieces by 19...Bg4 since as played White's b6/d6 pawn duo set up promotion tactics. At the end the elegant 33 Ba6! and 34 Bxb7! concludes a strategic masterpiece of which any world champion would be proud.
