For more than three years, Magnus Carlsen, a 22-year-old Norwegian, has been the uncrowned king of chess. It appears increasingly likely that within the next few days, he will officially wear the crown of world champion.
Carlsen has been the No. 1 player in the world almost continuously since January 2010, but the world champion has been Viswanathan Anand, 43, an Indian grandmaster, who won the title in 2007. To become world champion, it was necessary to defeat Anand in a match, but Carlsen did not earn the right to face him until last March, when he won the Candidates tournament in London.
The match for the title began a week ago in Chennai, India, Anand's hometown. It is a best-of-12 series, with wins counting as 1 point and draws a half-point. On Saturday, Carlsen won his second straight game. He now leads 4 points to 2, with 6.5 points needed to clinch the title. The seventh game will be Monday.
