Mr. Carlsen, 22, who has long been the world’s highest-rated player, become the first Norwegian to hold the crown and the second youngest undisputed champion ever behind Russian Garry Kasparov.
He’s also claimed international headlines for breakout beyond the insular world of chess — even appearing as a model.
Mr. Anand, 43, has held the chess crown since 2007 and is a sporting hero in his country. He had successfully defended the title in three previous matches, but proved no match for his implacable younger rival in the match’s critical moments.
Endgames blunders by the champion cost him critical points in Games 5 and 6, and a one-move oversight in a tense attacking battle in Game 9 all but sealed Mr. Anand’s fate. The final match score was 6½-3½ in Mr. Carlsen’s favor — with three wins and seven draws.
Mr. Anand in his postgame comments pointed to Game 5 as the match’s psychological turning point, a devastating endgame loss after four draws to open the match. Mr. Carlsen told reporters that Game 3 and 4 had been crucial for him, as he survived uncomfortable moments and realized “my opponent was just as nervous as I was.”
Mr. Anand pressed in Game 10 against the Norwegian’s Sicilian Defense, taking a slight edge into a knight-and-pawn ending. After both players obtained a new queen, Mr. Anand had three pawns and a queen to Mr. Carlsen’s queen and knight.
Black found a forcing variation to trade off all of the pieces, leaving the two players with just their kings for a 65-move draw. The game took just over five hours to play.
Mr. Carlsen will have to defend his new crown in just a year’s time. A candidates’ tournament is set for March in the Russian city of Khanty-Mansiysk to determine his challenger.
