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.[29] He obtained a score of 10½/13, losing just one game (against the highest-rated player of the C group, Duško Pavasovič).[30] 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.[31] 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).[32] Agdestein said that Carlsen had an excellent memory and played an unusually wide range of openings.[33] Carlsen's prowess caught the attention of Microsoft, which became his sponsor.[34]

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.[35]

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).[36] 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.[37]

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.[38]

In the Smartfish Chess Masters event at the Drammen International Chess Festival 2004–05, Carlsen defeated Alexei Shirov, then ranked No. 10[39] in the world, as well as the co-winner of the tournament.[40] 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.[41] Anand won 3–1.[42]

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.[43]

In October, Carlsen took first place at the Arnold Eikrem Memorial in Gausdal with a score 8/9 and a PR of 2792.[44]

Carlsen in Warsaw, 2005

At the end of 2005, Carlsen participated at the Chess World Cup in Khanty-Mansiysk, Russia. In the knockout tournament, he upset 44th-ranked Zurab Azmaiparashvili in round one, and proceeded to defeat Farrukh Amonatov and Ivan Cheparinov to reach the round of 16. There he lost to Evgeny Bareev,[45] but won against Joël Lautier and Vladimir Malakhov before losing again to Gata Kamsky. Carlsen finished in tenth place and became the youngest player to be an official World Championship Candidate.[46]

Carlsen qualified for a place in the Corus B group due to his first-place finish in Corus group C in 2004. His shared first place with Alexander Motylev with 9/13 (+6−1=6) qualified him to play in the Corus group A in 2007.[47]

At the 2006 international 'Bosna' tournament in Sarajevo, Carlsen shared first place with Liviu-Dieter Nisipeanu (who won on tiebreak evaluation) and Vladimir Malakhov; this could be regarded as Carlsen's first "A" elite tournament win, although it was not a clear first.[48]

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.[49] 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.[50]

Carlsen won the Glitnir Blitz Tournament in Iceland.[51] He achieved a 2–0 win over Viswanathan Anand in the semi-finals and achieved the same score in the finals.[52] He scored 6/8 in the 37th Chess Olympiad and achieved a PR of 2820.[53]

In the Midnight Sun Chess Tournament in Tromsø, Carlsen finished second to Sergei Shipov.[54] In the Biel Grandmaster Tournament, he placed second, beating the tournament winner Alexander Morozevich twice.[55]

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.[56]

With a score of 7½/15, Carlsen placed 8th out of 16 participants at the World Blitz Championship in Rishon LeZion, Israel.[57] 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.[58] 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.[59]

Carlsen playing Levon Aronian at Linares 2007

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.[60] 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.[61]

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.[62]

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.[63]

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.[64] 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)[65] after having a lost position at one point.[66] A game which attracted some attention was his sixth-round win over his father, Henrik Carlsen.[67]

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.[68]

Carlsen in 2008

In the top group A of the 69th Corus chess tournament, Carlsen scored 8/13, achieving a PR of 2830. Carlsen won five games, lost two and drew six, sharing first place with Levon Aronian.[69] At the Linares chess tournament, Carlsen had another 2800+ PR, scoring 8/14. He finished in sole second place, ½ point behind the winner World Champion Viswanathan Anand.[70]

In March, Carlsen played for the second time in the Melody Amber blind and rapid chess tournament, held in Nice for the first time. In the 11 rounds he achieved four wins, four draws and two losses in the blindfold, and three wins, two losses, and six draws in the rapid. This resulted in a shared fifth place in the blindfold, shared third place in the rapid and a shared second place in the overall tournament.[71]

Carlsen was one of 21 players in the six-tournament FIDE Grand Prix 2008–2010, a qualifier for the World Chess Championship 2012. In the first tournament, in Baku, Azerbaijan, he finished in a three-way tie for first place, with another 2800 PR. He later withdrew from the Grand Prix cycle despite his initial success, criticising FIDE for "changing the rules dramatically in the middle of a World Championship cycle".[72]

Carlsen won a rapid match against Peter Leko held in Miskolc, Hungary, scoring 5–3.[73] In June, Carlsen won the annual Aerosvit chess tournament,[74] finishing undefeated with 8/11 in a category 19 field and achieving a PR of 2877, his best PR at that point in his career.[75] Playing in the category 18 Biel Grandmaster Tournament, Carlsen finished third with 6/10, with a PR of 2740.[76]

In the Mainz World Rapid Chess Championship, Carlsen finished in second place after losing the final to defending champion Anand 3–1.[77] In the qualification round Carlsen scored 1½–½ against Judit Polgár, 1–1 against Anand and 1–1 against Alexander Morozevich.[78] In the category 22 Bilbao Masters, Carlsen tied for second with a 2768 PR.[79]

Playing in Group A of the 71st Corus chess tournament, Carlsen tied for fifth with a 2739 PR.[80] In the Linares chess tournament, Carlsen finished third with a 2777 PR.[81] Carlsen tied for second place with Veselin Topalov at the M-Tel Masters (category 21) tournament in Sofia, Bulgaria. He lost to eventual winner Alexei Shirov in their final game, dropping him from first.[82]

Carlsen won the category 21 Nanjing Pearl Spring tournament, 2½ points ahead of second-place finisher Topalov, the world's highest-rated player at the time. He scored an undefeated 8/10, winning every game as white (against Topalov, Wang Yue, Leko, Teimour Radjabov, and Dmitry Jakovenko), and also winning as black against Jakovenko. By rating performance, this was one of the greatest results in history, with a PR of 3002.[83] Chess statistician Jeff Sonas has declared it one of the 20 best tournament performances of all time, and the best chess performance of all time by a teenager.[84]

In the Tal Memorial, played from 5 to 14 November, Carlsen started with seven straight draws, but finished with wins over former FIDE World Champion Ruslan Ponomariov and Peter Leko. This result put Carlsen in shared second place behind former World Champion Vladimir Kramnik and equal with Ivanchuk.[85][86] After the Tal Memorial, Carlsen won the World Blitz Championship, played from 16 to 18 November in Moscow, Russia. His score of 28 wins, 6 draws and 8 losses left him three points ahead of Anand, who finished in second place.[87]

Carlsen at the World Blitz Championship 2009

Carlsen entered the London Chess Classic as the top seed in a field including Kramnik, Hikaru Nakamura, Michael Adams, Nigel Short, Ni Hua, Luke McShane and David Howell. He defeated Kramnik in round one and went on to win the tournament with 13/21 (three points were awarded for a win, and one for a draw; using classical scoring he finished with 5/7) and a PR of 2844, one point ahead of Kramnik. This victory propelled him to No. 1 of the FIDE rating list, surpassing Veselin Topalov.[88][89]

Based on his average ranking from the July 2009 and January 2010 FIDE lists, Carlsen qualified for the Candidates Tournament that would determine the challenger to World Champion Viswanathan Anand in the World Chess Championship 2012. In November 2010, however, Carlsen announced he was withdrawing from the Candidates Tournament. Carlsen described the 2008–12 cycle as "[not] sufficiently modern and fair", and wrote that "Reigning champion privileges, the long (five-year) span of the cycle, changes made during the cycle resulting in a new format (Candidates) that no World Champion has had to go through since Kasparov, puzzling ranking criteria as well as the shallow ceaseless match-after-match concept are all less than satisfactory in my opinion."[90]

In early 2009 Carlsen engaged former World Champion Garry Kasparov as a personal trainer.[91] In September their partnership was revealed to the public by Norwegian newspapers.[92][93]

Responding to a question in an interview with Time magazine in December 2009 as to whether he used computers when studying chess, Carlsen explained that he does not use a chess set when studying on his own.[94]

Carlsen won the 72nd Corus chess tournament played 16–31 January with 8½ points. His ninth-round loss to Kramnik ended a streak of 36 rated games undefeated.[95] Carlsen appeared to struggle in the last round against Fabiano Caruana, but saved a draw, leaving him half a point ahead of Kramnik and Shirov.[96]

In March it was announced that Carlsen had split from Kasparov and would no longer use him as a trainer,[97] although this was put into different context by Carlsen himself in an interview with the German magazine Der Spiegel, in which he stated that they would remain in contact and he would continue to attend training sessions with Kasparov.[98] In 2011, Carlsen said: "Thanks to [Kasparov] I began to understand a whole class of positions better. ... Kasparov gave me a great deal of practical help."[99] In 2012, when asked what he learnt from working with Kasparov, Carlsen answered: "Complex positions. That was the most important thing."[100]

Carlsen shared first place alongside Ivanchuk in the Amber blindfold and rapid tournament. Scoring 6½/11 in the blindfold and 8/11 in the rapid, Carlsen accumulated 14½ from a possible 22 points.[101] In May it was revealed that Carlsen had helped Anand prepare for the World Chess Championship 2010 against challenger Veselin Topalov, which Anand won 6½–5½ to retain the title. Carlsen had also helped Anand prepare for the World Chess Championships in 2007 and 2008.[102]

Carlsen played in the Bazna Kings Tournament in Romania on 14–25 June. The tournament was a double round robin involving Wang Yue, Boris Gelfand, Ruslan Ponomariov, Teimour Radjabov, and Liviu-Dieter Nisipeanu. He finished with 7½/10 and a 2918 PR, winning the tournament by two points ahead of Radjabov and Gelfand.[103] Carlsen then played in a rapid tournament 28–30 August at the Arctic Securities Chess Stars tournament in Kristiansund, Norway. The field featured World Champion Viswanathan Anand, female world No. 1 Judit Polgár, and Jon Ludvig Hammer. In the preliminary round robin, Carlsen scored 3½/6 to qualify for the final, second behind Anand.[104] In the final, Carlsen defeated Anand 1½–½ to win the championship.[105] Following this event, Carlsen suffered setbacks in his next two tournaments. In the 39th Chess Olympiad from 19 September to 4 October, he scored 4½/8, losing three games, to Baadur Jobava, Michael Adams, and Sanan Sjugirov; these were his first losses with the black pieces in more than a year.[106] His team, Norway, finished 51st out of 149 teams.[107]

Carlsen's next tournament was the Grand Slam Masters Final on 9–15 October, which he had qualified for automatically by winning three of the previous year's four Grand Slam chess events (2009 Nanjing Pearl Spring, 2010 Corus, 2010 Bazna Kings). Along with Carlsen, the finals consisted of World Champion Anand and the highest two scorers from the preliminary stage held in Shanghai in September: Kramnik and Shirov.[108][109] The average Elo of the participants at the time was 2789, making the Grand Slam Final the strongest chess tournament in history. In the first round, Carlsen lost with black to Kramnik; this was Carlsen's second consecutive loss to Kramnik, and placed his hold on the world No. 1 ranking in serious jeopardy. In his second round, Carlsen lost with the white pieces to Anand; this was his first loss as White since January 2010. Carlsen recovered somewhat in the latter part of the tournament, achieving a win over Shirov, and finishing with 2½/6. The tournament was won by Kramnik with 4/6.[110] Carlsen finished this tournament with a rating of 2802, two points behind Anand at 2804 who temporarily ended Carlsen's reign at world No. 1. These setbacks called into question from some whether Carlsen's activities outside chess, such as modelling for G-Star Raw, were distracting him from performing well at the chessboard.[111] Carlsen said he did not believe there was a direct connection.[112]

Carlsen's next tournament was the Pearl Spring chess tournament on 19–30 October in Nanjing, China, against Anand, Topalov, Vugar Gashimov, Wang Yue, and Étienne Bacrot.[113] This was the only tournament in 2010 to feature Anand, Carlsen and Topalov, at the time the top three players in the world, and was the first tournament in history to feature three players rated at least 2800. With early wins over Bacrot, Wang Yue, and Topalov with white, Carlsen took the early lead, extending his winning streak with white in Nanjing to eight. This streak was halted by a draw to Anand in round seven, but in the penultimate round Carlsen secured first place by defeating Topalov with black. This was his second victory in the tournament over the former world No. 1; his final score of 7/10 (with a PR of 2903) was a full point ahead of runner-up Anand.[114]

Carlsen at the 2010 London Chess Classic

On 5 November, Carlsen withdrew from the 2011 Candidates Tournament, having qualified as the highest rated challenger, citing dissatisfaction with the World Championship cycle format.

In the World Blitz Championship, held in Moscow on 16–18 November, Carlsen attempted to defend his 2009 title. With a score of 23½/38, he finished in third place behind Radjabov and winner Levon Aronian.[115] After the tournament, Carlsen played a private 40-game blitz match against Hikaru Nakamura,[116] winning with a score of 24½–15½.[117]

Carlsen won the London Chess Classic on 8–15 December in a field comprising World Champion Anand, Vladimir Kramnik, Nakamura, and British players Adams, Nigel Short, David Howell, and Luke McShane. Carlsen had a rocky start, losing his games to McShane and Anand in rounds 1 and 3, but winning with white against Adams and Nakamura in rounds 2 and 4. He joined the lead with a win over Howell in round 5, and managed to stay in the lead following a harrowing draw against Kramnik in round 6, before defeating Short in the last round. Since the tournament was played with three points for a win, Carlsen's +4−2=1 score put him ahead of Anand and McShane who scored +2=5 (a more traditional two-points-for-a-win system would have yielded a three-way tie, with Carlsen still on top, having the better tiebreaker due to four games with black—Anand and McShane played only three times with black).[118]

Carlsen competed in the GM-A group of the 73rd Tata Steel Chess Tournament (formerly called the Corus chess tournament) on 14–30 January in Wijk aan Zee in an attempt to defend his title; the field included World Champion Viswanathan Anand, Levon Aronian, former World Champion Vladimir Kramnik, Alexander Grischuk, Hikaru Nakamura, Ruslan Ponomariov, among others. Despite losing games with white against Anish Giri and reigning Russian champion Ian Nepomniachtchi, Carlsen finished with 8/13, including victories over Kramnik and tournament winner Nakamura.[119] Although Carlsen's performance raised his rating from 2814 to 2815, Anand's 8½/13 score elevated his rating to 2817, making him the world No. 1 for the March 2011 FIDE rating list.[120]

The first tournament victory of the year came in the Bazna Kings tournament, a double round robin played in Mediaș, Romania on 11–21 June. Carlsen finished with 6½/10, equal with Sergey Karjakin but with a better tiebreak score. Carlsen won his White games against Nakamura, Nisipeanu, and Ivanchuk and drew the rest of the games.[121]

Carlsen won the 44th Biel Grandmaster tournament, held from 16 to 29 July. He took clear first place with a score of 19/30 (+5−1=4; three points for a win) in a field comprising Fabiano Caruana, Maxime Vachier-Lagrave, Alexander Morozevich, Alexey Shirov and Yannick Pelletier, two points ahead of Morozevich. This was Carlsen's second title.[122][123]

The Grand Slam Chess Final was held as a double round robin with six players, in São Paulo (25 September – 1 October) and Bilbao (5–11 October). Although Carlsen had a slow start, including a loss against bottom-ranked Francisco Vallejo Pons, he finished +3−1=6, equal with Ivanchuk (whose +4−3=3 finish was equal due to three points for a win). Carlsen then won the blitz tiebreak against Ivanchuk. The other players were Anand, Aronian, Nakamura, and Vallejo Pons.[124]

Another tournament victory was achieved in the Tal Memorial in Moscow 16–25 November as a round robin with ten players. Carlsen won two games, against Gelfand and Nakamura, and drew the rest. Although he finished equal on points with Aronian, he placed ahead since the tiebreak was determined by the number of black games; Carlsen had five black games, while Aronian only had four.[125][126]

In the London Chess Classic, played 3–12 December, Carlsen's streak of tournament victories ended when he finished third, behind Kramnik and Nakamura. Carlsen won three games and drew five. Although he did not win the tournament, Carlsen gained rating points, rising to a new personal record of 2835.[127]

Carlsen at the 74th Tata Steel Chess Tournament in 2012

At the 74th Tata Steel Chess Tournament held on 14–29 January in Wijk aan Zee, Carlsen finished in a shared second place with 8/13, behind Aronian, and equal with Radjabov and Caruana. Carlsen defeated Gashimov, Aronian, Gelfand, and Topalov, but lost against Karjakin.[128] At the blitz chess tournament at Tal Memorial, held in Moscow on 7 June, Carlsen shared first place with Morozevich. In the main event (a category 22 ten-player round robin), he won two games and drew seven. He finished in first place, ahead of Radjabov and Caruana.[129]

Carlsen then went on to finish second in the Biel Grandmaster Tournament, with 18 points, just one point behind Wang Hao using the 3–1–0 scoring system. As in the Tal Memorial earlier in 2012, Carlsen managed to finish the tournament without any losses (+4−0=6). He also defeated the winner Wang in both of their individual games. In the exhibition blitz tournament at Biel before the GM tournament, Carlsen was eliminated (+1−2=0) in the first round by Étienne Bacrot. Bacrot deprived Carlsen of a win in the classical tournament by holding him to a draw in the final round. Carlsen would have won the classical tournament on the traditional 1–½–0 scoring system, with 7/10.[130]

The Grand Slam Chess Final was again held as a double round robin with six players, in São Paulo and Bilbao. Carlsen started with a loss against Caruana, but after three wins in the second (Bilbao) round, finished +4−1=5, equal first with Caruana, and ahead of Aronian, Karjakin and Anand. Carlsen won the tournament by winning both tiebreak games against Caruana.[131]

From 24 to 25 November, Carlsen took part in the chess festival "Segunda Gran Fiesta Internacional de Ajedrez" in Mexico City. As part of it, Carlsen took on an online audience (dubbed as "The World") with the white pieces and won. He then took part in the knockout exhibition event "Cuadrangular UNAM". Carlsen first beat Lázaro Bruzón 1½–½, thus qualifying for a final against Judit Polgár (who had in turn beat Manuel León Hoyos 1½–½). Carlsen lost the first game, but won the second one, and in the tiebreak defeated Polgár 2–0.[132][133]

Carlsen won the London Chess Classic in December with five wins (over McShane, Aronian, Gawain Jones, Adams and Judit Polgár) and three draws (against Kramnik, Nakamura and Anand).[134] This win, the third time Carlsen had won the tournament in the past four years, increased his rating from 2848 to a new record of 2861, breaking Kasparov's 13-year record of 2851.[134][135] By rating performance, this was one of the best results in history, with a PR of 2994.[136]

Carlsen in play during round seven of the 75th Tata Steel, 2013

Carlsen played in the 75th Tata Steel Chess Tournament from 11 to 27 January in Wijk aan Zee. In the 13-round tournament, he scored 10 points (+7−0=6), winning clear first 1½ points ahead of second-place finisher Aronian.[137] On 1 February, Danish GM Peter Heine Nielsen joined the team of assistants who helped Carlsen prepare for the Candidates Tournament in March. Before this, Nielsen was on Viswanathan Anand's team.[138]

Carlsen played in the 2013 Candidates Tournament, which took place in London, from 15 March to 1 April. He finished with +5−2=7, and won the tournament on tiebreak over Vladimir Kramnik. As a result, he earned the right to challenge Anand for the World Championship.[139]

In May, Carlsen played in the first edition of Norway Chess tournament. He finished second, scoring 5½/9 (+3−1=5), half a point behind Sergey Karjakin.[140]

Carlsen played in the Tal Memorial from 12 to 23 June. He finished second, with 5½/9, half a point behind Boris Gelfand. Carlsen ended the tournament with +3−1=5, losing to Caruana but beating Anand, Kramnik and Nakamura.[141] Later that month, Carlsen played a four-game friendly rapid match against Borki Predojević, which he won 2½–1½.[142]

In the Sinquefield Cup, held in September, Carlsen finished first, scoring 4½/6 (+3−0=3), a point ahead of Nakamura.[143]

Carlsen faced Anand in the World Chess Championship 2013, at Hyatt Regency in Chennai, India, from 9 to 22 November. Carlsen won the match 6½–3½ by winning games five, six and nine and drawing the remainder, becoming the new World Chess Champion.[144] Though he was the challenger, and less experienced than Anand, he handled the pressure with ease. He drew first blood in game 5 by taking advantage of a small mistake by Anand, and emerged victorious in games 6 and 9, making him the 16th undisputed World Chess Champion.

From 29 January to 4 February, Carlsen played in the Zurich Chess Challenge, winning the blitz event (+2−1=2) and the classical event (+3−0=2). He fared worse in the rapid event (+1−2=2), which counted towards the overall standings, but retained enough of a lead to win the tournament. The other players in the event were Aronian, Nakamura, Caruana, Gelfand and Anand.[145] On 22 March, Carlsen played a game for his club Stavanger in the final team match for promotion to the Norwegian Premier League. His win over Vladimir Georgiev helped his team to a 3½–2½ win over Nordstrand.[146]

Carlsen won the Vugar Gashimov Memorial in Şəmkir, Azerbaijan, played from 20 to 30 April. He played in the A group along with Caruana, Nakamura, Karjakin, Shakhriyar Mamedyarov and Radjabov. Carlsen started the tournament with 2/2, beating Mamedyarov and Nakamura.

He won against Grischuk in round 5, drew against Nakamura and Vachier-Lagrave in rounds 6 and 7, and defeated Aronian in round 8, but he lost the last round against Jon Ludvig Hammer, leaving him in seventh place and with a performance rating of 2693.[160] Carlsen said of this result: "It's just extremely frustrating not to be able to show anything close to what I am capable of in my home country."[161]

In the third game, Carlsen was defeated by Niemann, ending his 53-game unbeaten streak in classical chess that chess24 described as a "stunning victory".[252][253] Carlsen soon after announced his withdrawal in a tweet with a video of Portuguese football manager José Mourinho saying, "I prefer really not to speak. If I speak, I am in big trouble."[254][255] The New York Times stated that "online observers interpreted Mr. Carlsen's post as insinuating that Mr. Niemann cheated in some way during the game", though no concrete evidence of cheating had been found.[256] Carlsen's previous results still affect his FIDE rating; however, they will be removed from the tournament standing.[257] This was the first time in Carlsen's career to withdraw from a major event in progress, and was considered "virtually unprecedented" in top level chess.[255]

Two weeks later, Carlsen faced Niemann in the Julius Baer Generation Cup, a section of the Champions Chess Tour 2022, an online chess tour. Carlsen, playing as black, resigned after one move, continuing the scandal.[258] On September 26, Carlsen finally broke his silence and accused Niemann of cheating.[259] Subsequently, on October 20 Niemann filed a lawsuit against Carlsen and four other defendants, alleging five counts of action, including libel and slander.[260][261]

In October 2013, Carlsen co-founded a company, Play Magnus AS, with Espen Agdestein and Anders Brandt.[429] Based in Oslo, Norway, Play Magnus' first product was an iOS app, called Play Magnus, that allows the user to play a chess engine created using a database of thousands of Carlsen's recorded games from the age of five and up. Carlsen stated he wished for the app to encourage more people to play chess.[430][431] The apps Magnus Trainer and Magnus Kingdom of Chess followed in 2016 and 2018, respectively. In March 2019, Play Magnus merged with Chess24.com.[432] The group then acquired Chessable, an interactive marketplace and platform for learning chess, in September 2019.[433][434]

On 8 October 2020, Play Magnus AS was listed on the Oslo Stock Exchange. The listing raised 300 million kr (US$30.2 million) for the company, giving it a valuation of 796 million kr (US$85.8 million). Magnus Chess, an entity controlled by Carlsen and his family, owns 9.5% of Play Magnus AS.[435] Play Magnus subsequently acquired iChess in November 2020 for an undisclosed amount.[436][437]

In August 2022, Chess.com finalised an offer of acquisition for the Play Magnus Group.[438][439]
