2006
In the January 2006 fide list, at the age of 15 years and 31 days, he officially attained 2625 elo rating, which made Carlsen the youngest person to break the 2600 elo barrier. In 2008, Wesley So broke that record. Carlsen qualified for a place in the Corus B group from his 2004 first place in Corus group C. His shared first with Motylev with 9/13 (+6 −1 =6) qualified him to play in the Corus A group in 2007.
In the 2006 Norwegian Chess Championship, Carlsen was close to winning outright, but a last-round loss to Berge Østenstad again tied him for first place with Agdestein. The last-round loss deprived Magnus of beating Agdestein's record of becoming the youngest Norwegian champion ever. Nonetheless, in the play-off 19–21 November Carlsen won 3–1. After two draws in the initial full-time games, Magnus won both rapid games in round two, securing his first Norwegian championship.
Magnus won the 2006 Glitnir Blitz Tournament in Iceland. He won 2–0 over Viswanathan Anand (2003 FIDE World Rapid Chess Champion, 2004 Amber Rapid Chess Champion, 2007 FIDE Classical World Champion) in the semi finals. Carlsen also won 2–0 in the finals.

In the Midnight Sun Chess Tournament, Carlsen had some misses and came in second, beaten by Sergei Shipov (FIDE-Elo: 2576).
In the 2006 Biel grandmaster tournament, he achieved second place, after having beaten the eventual winner Alexander Morozevich twice (once with each color).
In the NH Chess Tournament held in Amsterdam in August 2006, Carlsen participated in an 'Experience' v 'Rising Stars' Scheveningen team match. The 'Rising Stars' won the match 22–28, with Carlsen achieving the best individual score for the youngsters, 6½/10 and a 2700 Elo performance, thus winning the right to participate in the 2007 Melody Amber tournament.
In the World Blitz Championship at Rishon LeZion, Israel in September 2006, he was number 8 of 16 participants with 7½/15 points.
In the rapid chess tournament Rencontres nationales et internationales d'échecs in Cap d'Agde, France he got to the semifinal, losing to Sergey Karjakin.
