The first top-flight tournament of the year, Corus, is under way in Wijk-aan-Zee, The Netherlands. The A group has the top three players in the world (World Champion Anand, ex-Champion Kramnik, and ex-FIDE Champion Topalov) as well as 11 other big names. Seventeen-year-old Magnus Carlsen shares the lead with Levon Aronian after three rounds with 2½ points.

The B and C groups are also very strong, and often more exciting. The 13-year-old Chinese girl Hou Yifan beat England's former World Championship finalist Nigel Short in Round 3 of the B group – a quite crushing defeat.

There is live coverage at the official site as well as at Chessdom, while ChessVibes has various video reports.
