Sven Magnus Øen Carlsen is a Norwegian chess grandmaster, No. 1 ranked player in the world and reigning World Chess Champion in classical and rapid. His peak rating is 2882, the highest in history.
Carlsen was regarded as a chess prodigy as a youngster, and became a Grandmaster in 2004, at the age of 13 years, 148 days. This made him the third youngest grandmaster in history. On 1 January 2010, at the age of 19 years, 32 days, he became the youngest chess player to be ranked FIDE world No. 1.
In November 2013, Carlsen won the title world chess champion, by defeating Viswanathan Anand in the World Chess Championship 2013. On the May 2014 FIDE rating list, Carlsen reached his top Elo rating of 2882, which is the highest rating in history. He successfully defended his title in November 2014, once again defeating Viswanathan Anand. The same year, he also won the World Rapid Championship and the World Blitz Championship, thus holding all three world championship titles. In 2015, Carlsen won the inaugural Grand Chess Tour, a series of three supertournaments featuring the 10 best chess grandmasters in the world. As of April 2016, he is ranked as number 1 in classical chess, in rapid chess, and in blitz chess.
Magnus Carlsen was known for his attacking style as a teenager, but has since developed into a more universal player. He does not rely on opening preparation as much as other top players, and plays a variety of openings in order to make it more difficult for opponents to prepare against him. His positional mastery and endgame prowess have drawn comparisons to those of former world champions José Raúl Capablanca, Vasily Smyslov, and Anatoly Karpov.
