Besides his team of seconds in Sofia, Viswanathan Anand was helped by some big names before or during his World Championship match against Veselin Topalov. Magnus Carlsen, Anish Giri, Garry Kasparov and Vladimir Kramnik all contributed to Anand's victory in Sofia. The World Champion Monday revealed this in an interview on Playchess.
Right after the end of the World Championship match, Viswanathan Anand revealed his team of seconds. As it turned out, the same names as two years ago in Bonn worked for the Indian: GMs Surya Ganguly, Rustam Kasimdzhanov, Peter Heine Nielsen and Radoslaw Wojtaszek. However, this week Anand revealed another, quite interesting list of helpers: Magnus Carlsen, Anish Giri, Garry Kasparov and Vladimir Kramnik.
In a remarkable interview with Frederic Friedel and GM Jan Gustafsson, held last Monday on Playchess, Anand first tells about his cooperation with world's number one Magnus Carlsen, who worked with Anand before.
Basically I had him as a sparring partner. We did check some openings together, but the basic idea was that I would get to play a lot with him. Very few people can simulate a real tournament situation like Magnus can. We played a lot of blitz, and I felt good, because I was able to test a lot of areas I was unfamiliar with before. With Magnus you can test almost any position, because he can play almost any position, and play it reasonably well. In that sense his practical skills are very helpful.
Carlsen worked with the retired, 13th World Champion Garry Kasparov last year and in fact Kasparov also offered his help to Anand himself. The Indian said about him:
Garry got in touch and said he wanted to help a little bit. I sent him some details about what we were planning to play… (...) I sent him some questions and he said he would check them against his own notes and let me know if it was okay.
Frederic Friedel, one of the founders of Chessbase and the editor of the English news page, then reveals that he put Anand in touch with Vladimir Kramnik, his opponent in the previous World Championship match. Anand about Kramnik's assistance:
He actually started participating actively. He was also very understanding – he knew I would go to sleep once in a while, so he was happily speaking to the other team members as well, especially Rustam. They started getting in touch with each other and he gave us quite a few heavy-duty ideas, so that was nice. Actually he got in touch consistently over the next few days, and I cannot think of anyone who was more relieved than him when I stopped playing the Elista ending. He said “it’s an awful ending, why do you keep defending it every day?”
The fourth name on Anand's 'remote seconds list' is the Dutch super-talent GM Anish Giri:
Anish also did a couple of days of training with me. It was very similar to what I was doing with Magnus – I got to test a lot of things. There were a lot of areas I had no practical experience with, like the Catalan which I was playing almost the first time, the Elista ending and so on. Anish also sat and went through that.
We recommend reading one of the most remarkable and revealing interviews we've ever seen on Chessbase. Part 1 is here, and part 2 here. In the interview several times "Topalov's computer cluster" is mentioned, and in fact today we received a brief interview with Topalov, from the World Championship organizers, in which this is explained:
1. Grandmaster Topalov, regardless of the outcome, during the match between you and Viswanathan Anand we watched your dominance in the openings when you played with the white pieces. What caused this fact?
- During my preparation for the match, me and my manager Silvio Danailov, we decided to approach something non-standard and to seek additional resources to increase the advantage over my opponent.It turned out that there is such a possibility, we found that in Bulgaria is installed and running one of the most powerful supercomputers in the world - Blue Gene / P of IBM. And because the computers and the chess software are a necessary component of the preparation of the modern grandmasters, we decided to use the vast computational power of this machine. The IBM’s Blue Gene/P has 8192 processors and you can imagine for how huge possibilities we are talking about.

The problem was the fact that in the world currently there is not any chess software whose source code is written to work with such a multiprocessor platform. However, me and Silvio, we did not gave up and he managed to gather an international team of leading experts who have created a project for a chess program that can use the computing power of this extraordinary supercomputer. And now is the time to express my great thanks to the General Manager of IBM Bulgaria Mr. Alexander Rakov and the IT architect of the company Mr. Yovko Lambrev for the access to the resources of Blue Gene / P they provided to us and that they have made enormous efforts that our idea become a reality. I want to thank to the Prime Minister of Bulgaria Mr. Boyko Borisov too, who allowed us the access to the supercomputer, which as you know is state owned.
So ultimately, even though I lost the match, I managed to achieve a dominance over Anand in the openings in all games, in which I played with the white pieces. This advantage was demonstrated very clear especially in the first game, when I won fast and with decisive priority.
What’s next for gm Veselin Topalov from now on?
- Short break and chess again. In my closest plans, however, it’s included an initiative to increase young people's interest in relation of the high technologies and the artificial intelligence, which will be held under my patronage in cooperation with IBM Bulgaria.
I will do it because of my direct experience I know how important are and will be the computers and high technologies for our future and the career development of the young people.
In a few days we will announce an essay contest among high school students from Sofia concerning a topic in the field of high technologies. First five best students will form a representative team which will play a mini chess tournament / three games / against the IBM’s supercomputer Blue Gene / P.
After each of the games I'm going to comment the game and will give my advices to the young players. IBM Bulgaria will arrange for the finalists meetings with its leading experts to get them acquainted with the vast world of high technologies.
If all goes as we imagined it, the initiative will become annual.

Sven Magnus Øen Carlsen (Norwegian: [sven ˈmɑŋnʉs øːn ˈkɑːɭsn̩]; born 30 November 1990) is a Norwegian chessgrandmaster and the current World Chess Champion. A chess prodigy, Carlsen earned his grandmaster title at the age of 13 years and 148 days.
Native to Tønsberg, Carlsen was introduced to chess at the age of 5 and played in his first tournament at the age of 8. He earned his grandmaster title in 2004 and was competing successfully against the world's strongest grandmasters by 2007. He surpassed an Elo rating of 2800 in 2009 and reached No. 1 in the FIDE rankings in 2010, becoming the youngest person ever to achieve those feats.
Carlsen became World Champion in 2013 by defeatingViswanathan Anand. In the subsequent year, he retained his title against Anand, won both the 2014 World Rapid Championship and World Blitz Championship, thus becoming the first player to simultaneously hold all three titles, and reached a peak rating of 2882, the highest in history. In 2016, he defended his title against Sergey Karjakin.
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 more difficult for opponents to prepare against him and reduce the effect of computer analysis. He has stated the middlegame is his favourite part of the game as it "comes down to pure chess." His positional mastery and endgame prowess have drawn comparisons to those of former World Champions Bobby Fischer, Anatoly Karpov, Vasily Smyslov, and José Raúl Capablanca.
Carlsen was born in Tønsberg, Norway, on 30 November 1990, to Sigrun Øen, a chemical engineer, and Henrik Albert Carlsen, an IT consultant. 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. 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. His father, a keen amateur chess player, taught him to play chess at the age of 5, although he initially showed little interest in the game. He has three sisters, and in 2010 he stated that one of the things that first motivated him to take up chess seriously was the desire to beat his elder sister at the game.
The first chess book Carlsen read was Find the Plan by Bent Larsen, and his first book on openings was Eduard Gufeld's The Complete Dragon. Carlsen developed his early chess skills by playing by himself for hours on end—moving the pieces around, searching for combinations, and replaying games and positions shown to him by his father. Simen Agdestein emphasises Carlsen's exceptional memory, stating that he was able to recall the areas, population numbers, flags and capitals of all the countries in the world by the age of five. Later, Carlsen had memorised the areas, population numbers, coat-of-arms and administrative centres of "virtually all" Norwegian municipalities. Carlsen participated in his first tournament—the youngest division of the 1999 Norwegian Chess Championship—at the age of 8 years and 7 months, and scored 6½/11.
Carlsen was later coached at the Norwegian College of Elite Sport by the country's top player, Grandmaster (GM) Simen Agdestein, who in turn cites Norwegian football managerEgil "Drillo" Olsen as a key inspiration for his coaching strategy. In 2000, Agdestein introduced Carlsen to Torbjørn Ringdal Hansen, a former Norwegian junior champion and later International Master (IM) and Grandmaster (GM), as Ringdal served a one-year siviltjeneste (an alternative civilian service programme) at the college. Over the course of this year, Carlsen's rating rose from 904 in June 2000, to 1907. Carlsen's breakthrough occurred in the Norwegian junior teams championship in September 2000, where Carlsen scored 3½/5 against the top junior players of the country, and a performance rating (PR) of about 2000. Apart from chess, which he studied about three to four hours a day, Carlsen's favourite pastimes included playing football and reading Donald Duck comics. Carlsen also practised skiing until the age of ten.
From autumn 2000 to the end of 2002, Carlsen played almost 300 rated tournament games, as well as several blitz tournaments, and participated in other minor events. In October 2002, he placed sixth in the European Under-12 Championship in Peñiscola. In the following month, he tied for first place in the World Under-12 Championship in Heraklio, placing second to Ian Nepomniachtchi on tiebreak. After this, he obtained three IM norms in relatively quick succession; his first was at the January 2003 Gausdal Troll Masters (score 7/10, 2453 PR), the second was at the June 2003 Salongernas IM-tournament in Stockholm (6/9, 2470 PR), and the third and final IM norm was obtained at the July 2003 Politiken Cup in Copenhagen (8/11, 2503 PR). He was officially awarded the IM title on 20 August 2003. After finishing primary school, Carlsen took a year off to participate in international chess tournaments held in Europe during the fall season of 2003, returning to complete secondary education at a sports school. During the year away from school, he placed joint-third in the European Under-14 Championship and ninth in the World Under-14 Championship.

Carlsen made headlines after his victory in the C group at the 2004 Corus chess tournament in Wijk aan Zee. Carlsen obtained a score of 10½/13, losing just one game (against the highest-rated player of the C group, Duško Pavasovič). As a result of the victory, 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 Carlsen sacrificed material to give mate in just 29 moves. Carlsen's 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 "Mozart of chess". Agdestein said that Carlsen had an excellent memory and played an unusually wide range of openings. Carlsen's prowess caught the attention of Microsoft, who became his sponsor.
Carlsen obtained his second GM norm at the MoscowAeroflot Open in February. On 17 March, in a blitz chess tournament in Reykjavík, Iceland, Carlsen defeated former World Champion Anatoly Karpov. The blitz tournament 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.
In the sixth Dubai Open Chess Championship, held 18–28 April, Carlsen obtained his third and final GM norm. This achievement made him the world's youngest GM at the time, as well as the second-youngest GM in history at the time (after Sergey Karjakin, who earned the title at the age of 12 years and 7 months). Carlsen played in the FIDE World Chess Championship, thus becoming the youngest player ever to participate in one, but was knocked out in the first round by Levon Aronian.
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.
In the Smartfish Chess Masters event at the Drammen International Chess Festival 2004–05, Carlsen defeated Alexei Shirov, then ranked No. 10 in the world, as well as the co-winner of the tournament. 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. Anand won 3–1.
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 draw had been revoked previously. The match was closely fought—Agdestein won the first game, Carlsen the second—so the match 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.
At the end of 2005, Carlsen participated at the Chess World Cup in Khanty-Mansiysk, Russia. In the knockout tournament, he upset the 44th-ranked Zurab Azmaiparashvili in round one, and proceeded to defeat Farrukh Amonatov and Ivan Cheparinov to reach the round of 16. There, Carlsen lost to Evgeny Bareev, but then won against Joël Lautier and Vladimir Malakhov before losing again to Gata Kamsky. Thus, Carlsen finished in tenth place and became the youngest player to be an official World Championship Candidate. In October, he took first place at the Arnold Eikrem Memorial in Gausdal with a score 8/9 and a PR of 2792.
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.
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.
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. Nonetheless, in the playoff held from 19–21 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.
Carlsen won the Glitnir Blitz Tournament in Iceland. He achieved a 2–0 win over Viswanathan Anand in the semifinals and achieved the same score in the finals. He scored 6/8 in the 37th Chess Olympiad and achieved a PR of 2820.
In the Midnight Sun Chess Tournament in Tromsø, Carlsen finished second behind Sergei Shipov. In the Biel Grandmaster Tournament, he placed second, beating the tournament winner Alexander Morozevich twice.
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.
With a score of 7½/15, Carlsen placed 8th out of 16 participants at the World Blitz Championship in Rishon LeZion, Israel. In the rapid chess tournament Rencontres nationales et internationales d'échecs in Cap d'Agde, France, he reached the semifinal, losing there to Sergey Karjakin. 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.
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. In the Linares chess tournament, Carlsen played against top-rated players Veselin Topalov, Viswanathan Anand, Peter Svidler, Alexander Morozevich, Levon Aronian, Peter Leko, and Vassily 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.
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.
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.
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. 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) after having a lost position at one point. A game which attracted some attention was his sixth-round win over his father, Henrik Carlsen.
Carlsen reached the semifinal 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 semifinal, he was eliminated by the eventual winner, Gata Kamsky, scoring ½–1½.
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. 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.
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.
Carlsen was one of 21 players in the six-tournament FIDE Grand Prix 2008–2009, 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".
Carlsen won a rapid match against Peter Leko held in Miskolc, Hungary, scoring 5–3. In June, Carlsen won the annual Aerosvit chess tournament, 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. Playing in the category 18 Biel Grandmaster Tournament, Carlsen finished third with 6/10, with a PR of 2740.
In the Mainz World Rapid Chess Championship, Carlsen finished in second place after losing the final to defending champion Anand 3–1. In the qualification round Carlsen scored 1½–½ against Judit Polgár, 1–1 against Anand and 1–1 against Alexander Morozevich. In the category 22 Bilbao Masters, Carlsen tied for second with a 2768 PR.
Playing in Group A of the 71st Corus chess tournament, Carlsen tied for fifth with a 2739 PR. In the Linares chess tournament, Carlsen finished third with a 2777 PR. 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.
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. 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.
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. 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.
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 the top of the FIDE rating list, surpassing Veselin Topalov.
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."
In early 2009 Carlsen engaged former World Champion Garry Kasparov as a personal trainer. In September their partnership was revealed to the public by Norwegian newspapers.
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.
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. 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.
In March it was announced that Carlsen had split from Kasparov and would no longer use him as a trainer, 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. 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." In 2012, when asked what he learnt from working with Kasparov, Carlsen answered: "Complex positions. That was the most important thing."
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. 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.
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. 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. In the final, Carlsen defeated Anand 1½–½ to win the championship. 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. His team, Norway, finished 51st out of 149 teams.
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. 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. 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. Carlsen said he did not believe there was a direct connection.
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. 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.
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. After the tournament, Carlsen played a private 40-game blitz match against Hikaru Nakamura, winning with a score of 23½–16½.
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).
