Sven Magnus Øen Carlsen[a] (born 30 November 1990)[1][2] is a Norwegian chess grandmaster who is the reigning five-time World Chess Champion, four-time World Rapid Chess Champion, and six-time World Blitz Chess Champion. Carlsen has held the No. 1 position in the FIDE world chess rankings since 1 July 2011 and trails only Garry Kasparov in time spent as the highest-rated player in the world. His peak rating of 2882 is the highest in history. He also holds the record for the longest unbeaten streak at the elite level in classical chess.[3]
A chess prodigy, Carlsen finished first in the C group of the Corus chess tournament shortly after he turned 13 and earned the title of grandmaster a few months later. At 15, he won the Norwegian Chess Championship, and at 17 he finished joint first in the top group of Corus. He surpassed a rating of 2800 at 18, the youngest at the time to do so. In 2010, at 19, he reached No. 1 in the FIDE world rankings, the youngest person ever to do so.
Carlsen became World Chess Champion in 2013 by defeating Viswanathan Anand. He retained his title against Anand the following year and won both the 2014 World Rapid Championship and World Blitz Championship, becoming the first player to hold all three titles simultaneously, a feat which he repeated in 2019 and 2022.[4][5] He defended his classical world title against Sergey Karjakin in 2016, against Fabiano Caruana in 2018, and against Ian Nepomniachtchi in 2021. Carlsen has declined to defend his title against Nepomniachtchi in 2023.[6]
Known for his attacking style as a teenager, Carlsen has since developed into a universal player. He uses a variety of openings to make it harder for opponents to prepare against him and reduce the utility of pre-game computer analysis. He has stated the middlegame is his favourite part of the game as it "comes down to pure chess".[7]
Carlsen was born in Tønsberg, Norway, on 30 November 1990[1] to Sigrun Øen, a chemical engineer, and Henrik Albert Carlsen, an IT consultant.[8] The family spent one year in Espoo, Finland, and then in Brussels, Belgium, before returning to Norway in 1998, where they lived in Lommedalen, Bærum. They later moved to Haslum.[9] Carlsen showed an aptitude for intellectual challenges at a young age. At two years, he could solve 50-piece jigsaw puzzles; at four, he enjoyed assembling Lego sets with instructions intended for children aged 10–14.[10]
Carlsen was coached at the Norwegian College of Elite Sport by the country's top player, Grandmaster (GM) Simen Agdestein,[8] who in turn cites Norwegian football manager Egil "Drillo" Olsen as a key inspiration for his coaching strategy.[18] In 2000, Agdestein introduced Carlsen to Torbjørn Ringdal Hansen, a former Norwegian junior champion and later International Master (IM) and Grandmaster (GM),[19] as Ringdal served a one-year siviltjeneste (an alternative civilian service programme) at the college.
Over the course of that year, Carlsen's rating rose from 904 in June 2000 to 1907. His breakthrough occurred in the Norwegian junior teams championship in September 2000, where he scored 3½/5 against the country's top junior players and gained a tournament performance rating (TPR) of around 2000.[20] Apart from chess, which he studied about three to four hours a day, his favourite pastimes included playing football and reading Donald Duck comics.[21] He also practised skiing until age ten.[22]
From autumn 2000 to the end of 2002, Carlsen played almost 300 rated tournament games, as well as in several blitz tournaments, and participated in other minor events.[23] In October 2002, he placed sixth in the European Under-12 Championship in Peñiscola.[24] The following month, he tied for first place in the 2002 World Under-12 Championship in Heraklion, placing second to Ian Nepomniachtchi on tiebreak.[25] He then obtained three IM norms in relatively quick succession: the first at the January 2003 Gausdal Troll Masters (score 7/10, 2453 PR); the second at the June 2003 Salongernas IM-tournament in Stockholm (6/9, 2470 PR); and the third at the July 2003 Politiken Cup in Copenhagen (8/11, 2503 PR). He was officially awarded the IM title on 20 August 2003.[26]
After finishing primary school, Carlsen took a year off to participate in international chess tournaments in Europe during the autumn of 2003, then returned to complete secondary education at a sports school.[27][28] During the year away from school, he placed joint-third in the European Under-14 Championship[29] and ninth in the 2003 World Under-14 Championship.[30]
Carlsen made headlines after his victory, at the age of 13, in the C group at the 2004 Corus chess tournament in Wijk aan Zee.[31] He obtained a score of 10½/13, losing just one game (against the highest-rated player of the C group, Duško Pavasovič).[32] As a result, he earned his first GM norm, and achieved a PR of 2702. Particularly notable was his win over Sipke Ernst in the penultimate round, when he sacrificed material to give mate in just 29 moves.[33] His victory in the C group qualified him to play in the B group in 2005, and it led Lubomir Kavalek, writing for the Washington Post, to give him the title "the Mozart of chess" (although, as pointed out by Edward Winter, the nickname had been given to many illustrious predecessors).[34] Agdestein said that Carlsen had an excellent memory and played an unusually wide range of openings.[35] Carlsen's prowess caught the attention of Microsoft, which became his sponsor.[36]
Carlsen obtained his second GM norm at the Moscow Aeroflot Open in February. On 17 March, in a blitz chess tournament in Reykjavík, Iceland, he defeated former World Champion Anatoly Karpov. It was a preliminary event leading up to a rapid knockout tournament beginning the next day. In that event, Carlsen was paired with Garry Kasparov, then the top-rated player in the world. Carlsen achieved a draw in their first game but lost the second, and was thus knocked out of the tournament.[37]
In the sixth Dubai Open Chess Championship, held 18–28 April, Carlsen obtained his third and final GM norm. It made him the world's youngest GM at the time, and the second-youngest GM in history at the time (after Sergey Karjakin, who earned the title at 12 years and 7 months).[38] Carlsen played in the FIDE World Chess Championship, becoming the youngest player ever to participate in one, but was knocked out in the first round by Levon Aronian.[39]
In July, Carlsen and Berge Østenstad, then the reigning Norwegian champion, tied for first in the Norwegian Chess Championship, each scoring 7/9. A two-game match between them was arranged to decide the title. Both games were drawn, which left Østenstad the champion because he had superior tiebreaks in the tournament.[40]
In the Smartfish Chess Masters event at the Drammen International Chess Festival 2004–05, Carlsen defeated Alexei Shirov, then ranked No. 10[41] in the world, as well as the co-winner of the tournament.[42] In the semifinals of the Ciudad de León rapid chess tournament in June, Carlsen played a four-game match against Viswanathan Anand, who was ranked No. 2 in the world at the time and had won the 2003 World Rapid Chess Championship.[43] Anand won 3–1.[44]
In the Norwegian Chess Championship, Carlsen again finished in shared first place, this time with his mentor Simen Agdestein. A playoff between them was played between 7 and 10 November. This time, Carlsen had the better tiebreaks, but the rule giving the title to the player with better tiebreak scores in the event of a 1–1 tie had been revoked. The match was closely fought—Agdestein won the first game, Carlsen the second—so it went into a series of two-game rapid matches until there was a winner. Carlsen won the first rapid game, Agdestein the second. Then followed three draws until Agdestein won the championship title with a victory in the sixth rapid game.[45]
Carlsen was close to winning the 2006 Norwegian Chess Championship outright, but a last-round loss to Berge Østenstad dropped him into another tie for first place with Agdestein. It also prevented Carlsen from beating Agdestein's record as the youngest Norwegian champion ever.[51] Nonetheless, in the playoff held from 19 to 21 September, Carlsen won 3–1. After two draws at standard time controls, Carlsen won both rapid games in round two, securing his first Norwegian championship win.[52]
Carlsen won the Glitnir Blitz Tournament in Iceland.[53] He achieved a 2–0 win over Viswanathan Anand in the semi-finals and achieved the same score in the finals.[54] He scored 6/8 in the 37th Chess Olympiad and achieved a PR of 2820.[55]
In the Midnight Sun Chess Tournament in Tromsø, Carlsen finished second to Sergei Shipov.[56] In the Biel Grandmaster Tournament, he placed second, beating the tournament winner Alexander Morozevich twice.[57]
In the NH Chess Tournament held in Amsterdam in August, Carlsen participated in an "Experience" vs. "Rising Stars" Scheveningen team match. The "Rising Stars" won the match 28–22, with Carlsen achieving the best individual score for the Rising Stars team (6½/10) and a 2700 PR, thus winning the right to participate in the 2007 Melody Amber tournament.[58]
With a score of 7½/15, Carlsen placed 8th out of 16 participants at the World Blitz Championship in Rishon LeZion, Israel.[59] In the rapid chess tournament Rencontres nationales et internationales d'échecs in Cap d'Agde, France, he reached the semi-final, losing there to Sergey Karjakin.[60] In November, Carlsen achieved a shared 8th place of 10 participants in the Mikhail Tal Memorial in Moscow with two losses and seven draws. He finished ninth in a group of 18 participants in the associated blitz tournament, which was won by Anand.[61]
Playing in the top group of the Corus chess tournament for the first time, Carlsen placed last with nine draws and four losses, scoring 4½/13.[62] In the Linares chess tournament, Carlsen played against top-rated players Veselin Topalov, Viswanathan Anand, Peter Svidler, Alexander Morozevich, Levon Aronian, Peter Leko, and Vasyl Ivanchuk. Despite being rated significantly lower than any of them, he finished in second place on tiebreaks with 7½/14, having scored four wins, seven draws and three losses, and achieving a PR of 2778.[63]
Carlsen played for the first time in the Melody Amber blind and rapid chess tournament in Monte Carlo in March. In the 11 rounds, he achieved eight draws and three losses in the blindfold games, as well as three wins, seven draws and one loss in the rapid games. This resulted in a shared ninth place in the blindfold, shared second place in the rapid (behind Anand), and a shared eighth place overall.[64]
In May and June, he participated in the Candidates Tournament for the FIDE World Chess Championship 2007, facing Levon Aronian in a six-game match at standard time controls, which Carlsen drew (+2−2=2) by coming from behind twice. The four-game rapid playoff was drawn as well (+1−1=2), with Carlsen winning the last game to stay in the match. Eventually, Aronian eliminated Carlsen from the tournament after winning both tiebreak blitz games.[65]
In July and August, Carlsen won the Biel Grandmaster Tournament with a 6/10 record and a PR of 2753. His score was matched by Alexander Onischuk and they played a match to break the tie. After drawing two rapid and two blitz games, Carlsen won the armageddon game.[66] Immediately after the Biel tournament, Carlsen entered the open Arctic Chess Challenge in Tromsø, but his fourth-place result with +5=4 was a slight underperformance in terms of rating. In the first round, Carlsen conceded a draw to his classmate Brede Hagen (rated 2034)[67] after having a lost position at one point.[68] A game which attracted some attention was his sixth-round win over his father, Henrik Carlsen.[69]
Carlsen reached the semi-final round of the World Chess Cup in December, after defeating Michael Adams in the round of 16 and Ivan Cheparinov in the quarterfinals. In the semi-final, he was eliminated by the eventual winner, Gata Kamsky, scoring ½–1½.[70]
