MAGNUS CARLSEN
(born Nov-30-1990, 34 years old) Norway

[what is this?]

Magnus Carlsen (full name: Sven Magnus Øen Carlsen) was the 16th undisputed World Champion. He wrested the crown from Viswanathan Anand in November 2013 and successfully defended it a year later. In November 2016, Carlsen retained his crown when he defeated the challenger, Sergey Karjakin, in the rapid game tiebreaker after the 12-game classical match was tied. In November 2018, he again won the rapid tiebreaker to defend his title, this time against Fabiano Caruana in London. In December 2021, he successfully defended his title a fourth time in the Carlsen - Nepomniachtchi World Championship Match (2021), routing Ian Nepomniachtchi 7.5-3.5 (68.2%). Citing the pressure of preparing for and playing a title match every two years, Carlsen announced in 2022 that he would not defend his crown.

Landmarks

FM (2002); IM (2003); GM (2004); vice-World U12 World Champion (2002); Norwegian Champion (2006); Candidate (2007 & 2013); World Champion (2013, 2014, 2016, 2018 & 2021); World Rapid Champion (2014, 2015, 2019, 2022 & 2023) and World Blitz Champion (2009, 2014, 2017, 2018, 2019, 2022, 2023 & 2024 (=1st)), winner of the Grand Chess Tour (2015), five-time winner at Wijk aan Zee (2008 (jointly with Levon Aronian), 2010, 2013, 2015 & 2016).

Carlsen has been the world's top ranked player since January 2010, apart from six months between November 2010 and June 2011 when he was #2, and possesses the highest standard FIDE rating ever posted, as well as the highest ever live rating. In January 2016, he became the first person to be the world #1 in standard, rapid and blitz chess.

Master Norms

<IM norms> Carlsen earned his first IM norm in January 2003, at the Gausdal Troll Masters, where he scored 7/10. His second IM norm came in June 2003, at the Salongernas IM-tournament in Stockholm, where he scored 6/9, and his third and final IM norm came in the following month, at the 2003 Politiken Cup in Copenhagen, where he scored 8/11.

<GM norms> In early 2004, Carlsen made a major international impact when he won Corus C with 10.5/13, easily earning his first grandmaster norm and securing his entry to the Corus B in 2005. Carlsen obtained his second grandmaster norm in the Aeroflot Open (2004) in February and his third grandmaster norm at the sixth Dubai Open (2004), held between 18th and 28th April.

Background:

Carlsen was born in Tønsberg, Vestfold. His parents are the late Sigrun Øen and Henrik Carlsen, both engineers. Carlsen's father taught him chess at the age of eight, after which he soon played his first tournament, a junior (Miniputt) Norwegian championship. Carlsen was coached by seven-time Norwegian Champion Simen Agdestein and Torbjorn Ringdal Hansen. He was awarded the title of International Master in 2003, at the age of 12 years, 7 months and 25 days. In 2004, after having gained over 300 rating points in little over a year, Carlsen became the second-youngest grandmaster in chess history at the time, behind only Sergey Karjakin, at the age of 13 years, 4 months and 27 days. Parimarjan Negi later pipped his record by five days to become the second youngest grandmaster ever.

Championships:

<Age>: Carlsen won the Norwegian U11 Championship in 2000 and the U10 Nordic Championship in 2001. In 2002, he placed =1st in the Open Norwegian Junior Championship with 5.5/7, but easily won the same event the following year with 6/6. Carlsen started with 4/4 at the 2002 U12 European Championship, but faded to finish sixth. In the 2002 U12 World Championship a few weeks later, Carlsen was sole leader entering the last round, but was held to a draw by David Howell, enabling Ian Nepomniachtchi to equal his score and to win on tiebreak. He placed equal third at the 2003 U14 European Championship, half a point behind Sergei Zhigalko and Tornike Sanikidze, a short time later, finishing in a ninth-place tie with 7.5/11 at the World U14 Championship in Halkidiki.

<National and Continental>: A couple of weeks after being eliminated from the FIDE World Championship Knockout Tournament (2004) (see below), Carlsen placed =1st in the 2004 Norwegian Championship. However, after a two-game play-off match with co-leader and until then, six-time Norwegian champion, Berge Ostenstad was drawn, Østenstad was declared winner on tiebreak. In the 2005 Norwegian Chess Championship, Carlsen again finished in a shared first place, this time with his mentor Simen Agdestein. A rapid game playoff between them resulted in Agdestein's victory by 3.5-2.5 (+2 -1 =3). Carlsen finally won the Norwegian Championship in 2006, after defeating Simen Agdestein in a tie-break match.

Carlsen's first, and so far only participation in the continental championship provided a solid 22-point boost to his rating when he scored 8/13 in the European Championship (2005).

<World>: Carlsen qualified for the FIDE World Championship Knockout Tournament (2004), but was eliminated in the first round tiebreaker by Levon Aronian. His hopes to become a contender for the World Championship in the future took a big step forward by placing tenth at the World Cup (2005), becoming the youngest player ever to qualify for the Candidates. In his first Candidates match, held in Elista in May, Carlsen drew 3-3 in the six slow games of the World Championship Candidates (2007) before losing in rapid-play tie-breaks. He reached the final four in the World Cup (2007) before being defeated in the semi-finals by the eventual winner, Gata Kamsky. Carlsen's final placing in the 2007 World Cup qualified him for participation in the FIDE Grand Prix for 2008-09. Soon afterwards, he tied for first place in the Baku Grand Prix (2008), the first round of FIDE's inaugural Grand Prix series. Carlsen later withdrew from the Grand Prix cycle despite his excellent result in Baku, complaining about "dramatic changes to ... regulations." and that ‘changing the rules dramatically in the middle of a cycle is simply unacceptable.'

On the basis of his rating, Carlsen qualified for the Candidates Tournament that would determine the challenger to World Champion Viswanathan Anand in 2012. In November 2010, however, Carlsen announced he was withdrawing from the Candidates tournament. Carlsen described the 2008â€"12 cycle as not "...sufficiently modern and fair", and added 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." Carlsen qualified for the World Championship Candidates (2013) that was played in London, again on the basis of his rating. He placed first ex aequo with Vladimir Kramnik on 8.5/14 after both players lost their last round games, but as the first tiebreaker (score against each other in the tournament which was 1-1) failed to break the tie, he won on the second tiebreak which stipulated that the player with the greater number of wins takes first place; he had scored five wins to Kramnik's four. During the tournament, Carlsen set a new live rating record of 2878.9 after he defeated Gelfand in round 10.

In November 2013, Carlsen won the Anand - Carlsen World Championship Match (2013) that was staged in Chennai. The first four games were drawn before Carlsen won the fifth and sixth games. The seventh and eighth games were drawn, with Carlsen then winning the ninth game and drawing the tenth and last game to win by 6.5-3.5 (+3 =7).

World Championship Defense 2014

In Carlsen's first World Championship title defense against Anand - who won the right to challenge for the title by winning the World Championship Candidates (2014) that was held in March 2014 - in Sochi in Russia in November 2014.

The first game of the Carlsen - Anand World Championship Match (2014) was a fighting draw with Carlsen playing Black and successfully defending a Grunfeld. He drew first blood in game two playing the White side of a quiet Ruy Lopez, breaking down Black's defenses before the first time control. After the first rest day, Anand struck back strongly playing the White side of a Queen's Gambit Declined (D37), and overcame Carlsen before the first time control. In game 4, Anand played the Sicilian but Carlsen steered the opening into a quiet positional struggle that ended in a draw. Game 5 featured a Queen's Indian Defense by Carlsen which also ended in a draw. Game 6 may have been the turning point in the match. Anand missed a simple tactical stroke as Black that would have given him a very strong, if not winning position and the lead in the match. After missing this continuation, Anand's game weakened and Carlsen brought home the point to take the lead in the match for the second time.

Game 7 was another Berlin Defense by Anand who encountered difficulties and surrendered a piece for two pawns. However, his defense kept Carlsen at bay for 122 moves before the game was finally drawn due to insufficient mating material on the board. Game 8 in the match was another QGD, with Carlsen playing Black introducing an innovation from his home preparation that guaranteed him a relatively easy draw. After another rest day, play resumed with Carlsen playing the White side of a Ruy Lopez that turned into a Berlin Defense by Anand. The game quickly came to an end through a draw by repetition, with Carlsen content to maintain his one-point lead. In Game 10, Carlsen again defended a Grunfeld, albeit not as convincingly as in Game 1. However, he defended a long initiative by Anand to secure a draw to continue to maintain his one point lead. Game 11 was another Berlin Defense by Anand which turned into a complex and hard fought middle game following an innovation by Anand on the queenside, which was followed by an exchange sacrifice. Carlsen successfully defended to bring home the final point needed to secure his title for another two years.

Match result: Carlsen won by 6.5-4.5 (+3 -1 =7).

World Championship Defense 2016

Carlsen's second defense of his classical world title was in November 2016, starting November 11th, in New York City. Sergey Karjakin won the right to challenge him by finishing clear first in the World Championship Candidates (2016). Carlsen retained his title when he drew the classical games 6-6 (+1 -1 =10) and won the rapid game tiebreaker 3-1 (+2 =2). See Carlsen - Karjakin World Championship Match (2016) for more information.

World Championship Defense 2018

Carlsen exercised his right as World Champion to participate in the World Cup (2017), where he defeated the lowest seeded player, Nigerian IM Oluwafemi Balogun in round 1 and veteran Russian GM Aleksey Dreev in round 2. In round 3, however, Carlsen was eliminated by Xiangzhi Bu by 0.5-1.5, having lost the first game to a sacrificial attack by the Chinese GM. In the Carlsen - Caruana World Championship Match (2018), GM Carlsen successfully defended his world title for the 3rd time when he beat Fabiano Caruana, the winner of the World Championship Candidates (2018) tournament.

World Championship Defense 2021

Carlsen as world champion again qualified for the World Cup (2021). He received a bye in the first round. In the second and third rounds he swept Sasa Martinovic and Aryan Tari by 2-0 scores. In the fourth round he and Radoslaw Wojtaszek drew their two classical games. Carlsen scored 1.5/2 in the first rapid playoff to advance. In Round 5, Andrey Esipenko proved a much greater challenge. The two drew both classical games, and the first pair of rapid games. In the second rapid playoff, Carlsen won the first game but Esipenko won "on demand" to tie the playoff. In the blitz playoff, Carlsen finally scored 2-0 to advance. In the quarterfinals, Carlsen beat Etienne Bacrot 2-0. In the semifinals, Carlsen and Duda drew their two classical games and their first rapid playoff game. Duda as Black won their second playoff game to advance to the finals, where he beat Sergey Karjakin. Carlsen had to settle for third place, which he achieved by blanking Vladimir Fedoseev 2-0. This was Carlsen's fourth World Cup (2005, 2007, and 2017 being the others), and the second time he had reached the semifinals (2007 being the first).

Carlsen won the Carlsen - Nepomniachtchi World Championship Match (2021). The first five games were drawn. Carlsen won the sixth game, an epic 137-move marathon that was the longest game in world championship history. This game seemed to break Nepomniachtchi's spirit. After an uneventful draw in the seventh game, Carlsen scored 3.5 out of 4 in the remaining games to end the match.

Abdication

Nepomniachtchi again won the Candidates tournament, dominating the World Championship Candidates (2022) by 1.5 points. Carlsen had previously announced his hope that the 19-year-old Alireza Firouzja would win the tournament, and had stated that he was considering not competing for the 2023 world championship. On July 20, 2022, International Chess Day, Carlsen announced that he would not defend his title the following year. In April 2023 Nepomniatchchi and Ding Liren (who had finished second in the Candidates tournament), contested the Nepomniachtchi - Ding World Championship Match (2023). On April 30, 2023 Ding won, becoming the 17th world champion and ending Carlsen's reign.

Classical Tournaments:

<2004-2007> Carlsen placed 3rd at the Sigeman & Co (2004) followed later that month with a solid =3rd place at the Politiken Cup 2004, a half point behind the leaders Darmen Sadvakasov and compatriot Leif Erlend Johannessen. In October 2005, he won the Gausdal Bygger'n Masters in Norway with 8/9 ahead of 9 other grandmasters. He continued to improve in 2006, tying Alexander Motylev for first place in Corus Group B (2006). After several more strong performances during the year, including 6.5/9 at the Reykjavik Open (2006), =2nd at Bosna Sarajevo Tournament (2006), =2nd behind Sergei Shipov at the Midnight Sun Challenge at Breivika videregaende skole in Norway, =2nd at Biel Int'l Festival (2006) (after beating the winner Alexander Morozevich twice), first at the Gausdal Classics GM-A and a joint second-place finish at Morelia-Linares (2007), he crossed the 2700-mark, the youngest player ever to do so. A relatively poor result at Dortmund Sparkassen (2007) (3/7) was followed by a win at Biel Chess Festival (2007) (His score was equaled by Alexander Onischuk and so they played a tie-breaker match to determine the winner. After drawing two rapid and two blitz games, Carlsen won the Armageddon game) and a par for rating =2nd at the Arctic Chess Challenge (2007) where he scored 7/9, a half point behind the leader Alexander Moiseenko, and 3rd at the Tal Memorial (2007) in November 2007.

<2008-2009> In 2008 Carlsen was the joint winner of Corus Group A (2008) A-Group together with Levon Aronian, and placed second in Morelia-Linares (2008) behind Anand. He won clear first place at Aerosvit (2008) with a dominant 8/11 score. His "disappointing" third placement at 41st Biel International Chess Festival (2008) with 6/10, a half point behind joint winners Leinier Dominguez Perez and Evgeny Alekseev, was nevertheless still a 2740 performance, whilst his equal second in the Grand Slam Chess Final (2008) with 5.0/10 was a 2768 performance. His relatively meagre 7/13 at Corus Group A (2009) was followed by equal second placement behind Kramnik at Dortmund Sparkassen (2009) with a 2773 performance and 2nd with 5/9 at the M-Tel Masters (2009). The arrival of Garry Kasparov in 2009 as his coach enabled Carlsen's finest tournament performance to date, and one of the best tournament results in the history of chess. Carlsen eclipsed a stellar field consisting of Topalov, Peter Leko, Dmitry Jakovenko, Teimour Radjabov and Yue Wang to win clear first prize with 8/10 at the category XXI Pearl Spring Chess Tournament (2009). Carlsen's performance rating for the tournament was a record 3002 and lifted his FIDE rating in the November 2009 list to 2801, which made him only the fifth player to surpass 2800, and easily the youngest. After a slow start, Carlsen placed equal second with Vasyl Ivanchuk behind Vladimir Kramnik in the Category XXI Tal Memorial (2009), which fielded ten of the world's top thirteen rated players. He saw out 2009 with a win at the London Chess Classic (2009), a point ahead of Kramnik, a result which pushed him to the top of the world ratings in January 2010.

<2010-2012> In 2010, Carlsen's success continued, winning Corus Group A (2010) outright with 8.5/13, half a point ahead of joint second place finishers Kramnik and Alexey Shirov. In June, he won the category XXI King's Tournament (2010) in Bazna in Romania by a clear two points with 7.5/10 and a 2918 performance. Following mediocre performances at the 2010 Olympiad and the category XXII Grand Slam Chess Final (2010), Carlsen returned to form by winning the category XXI Nanjing Pearl Spring Tournament (2010) outright with 7/10 (+4 -0 =6) and a 2901 rating performance, a full point ahead of World Champion Anand who took outright second with 6/10, and finishing the year by winning the London Chess Classic (2010) for the second time in succession. After a slow start in the Tata Steel Group A (2011) super tournament, Carlsen finished =3rd with Levon Aronian behind Hikaru Nakamura and Anand with 8/13 and a performance rating of 2821. He followed up in June by winning the Bazna King's Tournament (2011) on tiebreak ahead of Karjakin, both finishing with 6.5/10, and by winning Biel Chess Festival (2011) in July with a round to spare and with a final score of 7/10 (TPR 2835). After another characteristically slow start, Carlsen placed =1st with Ivanchuk at the Grand Slam Chess Final (2011) with 15 points under the Bilbao scoring system (+3 -1 =6) and a 2842 performance rating, ultimately winning the tournament in a blitz tiebreaker. Then in November 2011, Carlsen won the Tal Memorial (2011) on tiebreak with 5.5/9 (+2 =7 -0 and a TPR of 2850) over Aronian. Carlsen finished 2011 with 3rd place at the category 20 London Chess Classic (2011) behind Kramnik and Nakamura, scoring +3 =5 (TPR of 2879). 2012 started with =2nd (+4 -1 =8; TPR 2830) behind Aronian and alongside Radjabov and Fabiano Caruana at the Category 21 Tata Steel Group A (2012). He won the category 22 Tal Memorial (2012) outright with 5.5/9 (+2 =7) and a TPR of 2849. The month after his strong results in the World Blitz he finished outright second behind Hao Wang in the Grandmaster Tournament of the Biel Chess Festival (2012). In October 2012, Carlsen repeated his 2011 feat at Bilbao by winning the Grand Slam Chess Final (2012) in a tiebreaker, this time against Caruana. He finished up 2012 by winning the London Chess Classic (2012), the third time he has done so, with a score of 6.5/8 (+5 =3 -0) and a TPR of 2994 (only fractionally below his record effort at Pearl Springs in 2009). London 2012 was also made historic for the fact that Carlsen's result lifted his January 2013 rating to a new record, exceeding Kasparov's record 2851 by 10 points.

<2013> Building on his achievements of 2012, Carlsen won the category 20 Tata Steel Group A (2013) tournament with a round to spare, his final score being 10/13. He also set a new live rating record of 2874 after his round 12 win over Nakamura, although this was superseded at the Candidates in March. In May 2013 he played in the category 21 Norway Chess (2013) held in the Stavanger Region of Norway and came 2nd with 5.5/9, half a point behind the winner Sergey Karjakin; in the preliminary Norway Chess (Blitz) (2013) held to determine the draw, he came 2nd with 6/9 behind Karjakin, thereby earning 5 games as White out of the 9 to be played. In June he again came outright 2nd, this time at the category 22 Tal Memorial (2013), half a point behind the winner Boris Gelfand. His last hit out before the World Championship match against Anand in November 2013 was the category 22 double round robin Sinquefield Cup (2013), which he won outright with 4.5/6 (+3 =3; TPR of 2966).

<2014> Carlsen's first tournament as World Champion was the Zurich Chess Challenge (2014), the first ever category 23 tournament (average rating 2801). He came from behind to take equal first with Aronian in the Zurich Chess Challenge (Blitz) (2014), which determined the colors in the main event (Carlsen has 4 whites and 1 black). By round 4 of the standard time event, he extended his live rating to 2882.6, breaking the record he established in round 3. His round 5 draw with Anand enabled him to finish the standard time event in first place, 2 scoring points ahead of Aronian. He needed 3.5/5 in the Zurich Chess Challenge (Rapid) (2014) played on the final day to guarantee his win in the event, however his 2/5 result was sufficient to win the combined event by one point under the scoring system used. His next event was the category 22 Gashimov Memorial (2014), a new event in honor of the late Azeri GM Vugar Gashimov, which he won outright with a score of 6.5/10, defeating Fabiano Caruana, his rival for first prize, in the last round. Although he was the only undefeated player at the Norway Chess (2014), he won insufficient games to win the event, which was successfully defended by last year's winner, Sergei Karjakin. In August 2014, he played in the category 23 (only the second such strength event) Sinquefield Cup (2014) and came outright second with 5.5/10, 3 points behind Caruana, the tournament's runaway winner.

<2015> Following the successful defense of his title against Anand in November 2014, Carlsen won the Tata Steel Masters (2015) outright with a score of 9/13 (+6 -1 =6), his six wins scored in succession after starting the event poorly with two draws and a loss. In April 2015, Carlsen won the category 21 Gashimov Memorial (2015) outright for the second year in succession with a powerful score of 7/9 (+5 =4), a full point clear of a resurgent Viswanathan Anand, who was outright runner up with 6/9. This high was followed by a low at the category 22 Norway Chess (2015) in Stavanger in June 2015, when he crashed and burned to his worst tournament result in almost a decade. After losing his first round game on time to Topalov in a won position, Carlsen never recovered and registered a 3.5/9 (+2-4=3) result that slashed 23 points from his rating. A slow start in the category 22 Sinquefield Cup (2015) following an early loss to Topalov, was followed by three successive wins which enabled Carlsen to draw level with the leader by round 5, before the rest day. However, a crucial loss to Grischuk from an advantageous position and missed opportunities to win against Nakamura relegated him to equal second in the event, a point behind the outright winner Levon Aronian. This result also caused him to shed a few ratings points.

Still struggling with his form, Carlsen began his campaign at the category 23 London Chess Classic (2015) with his characteristic slow start, but was able to finish equal first in the ninth and final round with a win over Alexander Grischuk, scoring 5.5/9 alongside Anish Giri and a surging Maxime Vachier-Lagrave. A three way rapid game tiebreak resulted in Carlsen winning the tournament as well as the Grand Chess Tour of 2015. He finished 2015 with a flourish when he won the powerful Qatar Masters (2015) by sharing first with an undefeated 7/9, then winning 2-0 in the blitz playoff against Yangyi Yu. His tiebreak wins against Yu Yangyi also elevated him back to world #1 in blitz.

<2016> The year started in the best possible way for Carlsen when he scored 9/13 to win outright at the category 20 Tata Steel Masters (2016) event, a point ahead of Caruana and Ding Liren. This was his fifth win at Wijk aan Zee, tying with Anand for the record number of wins at this event, which has been running since 1938. In April, he won the Norway Chess (2016) event for the first time, scoring 6/9 to finish outright first, a half point ahead of outright second placed Aronian who won their individual game; Carlsen also won the preliminary Norway Chess (Blitz) (2016) with 7.5/9, a point ahead of outright second placed Giri, to win the right to five starts as white in the nine round principal tournament. In July, Carlsen emerged as the outright winner of the Bilbao Masters (2016), well ahead of the runner up Nakamura.

<2017> Wesley So broke Carlsen's winning run at Wijk aan Zee, with the latter finishing outright second on 8/13 at the Tata Steel Masters (2017). In April Carlsen finished equal second alongside Caruana with 4/7 (+1=6), a point and a half behind outright winner Aronian at the category 20 GRENKE Chess Classic (2017). After easily winning the Norway Chess (Blitz) (2017) to determine the draw for the main event, Carlsen returned his worst result in over a decade to score 4/9 at the category 22 Norway Chess (2017), narrowly missing out on last place and coming to within one game of losing his number one world ranking. He regained some form at the category 22 Sinquefield Cup (2017), placing second with 5.5/9, half a point behind the winner Vachier-Lagrave, the only player who defeated Carlsen in this event. He seems to have returned to form with an uncontested first place in the powerful Isle of Man Masters (2017), finishing with 7.5/9, half a point clear of Anand and Nakamura, and also boosting his rating back to 2837 (live), his best since April 2017. His equal 3rd at the London Chess Classic (2017) enabled him to win the 2017 Grand Chess Tour.

<2018> The new year saw a continuation of Carlsen's improved form when he won the Tata Steel Masters (2018) in a 2 game blitz tiebreaker from Giri, after both finished on 9/13. This also improved his rating to its highest (2843) since November 2016. His second place to Fabiano Caruana, the next Challenger for Magnus's title, with 5.5/9 at the GRENKE Chess Classic (2018) in March 2018 was followed in the next month by Carlsen returning to the winner's circle by winning the category 22 Gashimov Memorial (2018), half a point clear from the runner-up Ding Liren, who incidentally reached his peak rating and ranking (world #5) to date for his result in this event. After a promising start in the first round of the Norway Chess (2018) when he defeated his next title challenger and winner of the 2018 Candidates tournament, Fabiano Caruana, Carlsen lost a game to Wesley So and conceded the lead to Caruana, who ultimately won the tournament; Carlsen placed equal second with 4.5/8, half a point from the lead. After his best start in a major tournament in recent years with two wins in the first two rounds, Carlsen gradually lost ground in the category 20 Biel (2018) with a string of draws, culminating in a loss in the penultimate round to Shakhriyar Mamedyarov which enabled the latter to win the event with a round to spare. At Sinquefield Cup (2018) he was in a three way tie for first with Levon Aronian and Fabiano Caruana, all three with +2 -0 =7.

<2019>He also participated and took first place at Tata Steel Masters (2019) scoring 9/13 (+5 -0 =8) and then at the Gashimov Memorial (2019) took first again, 7/9 (+5 -0 =4). And once again first at GRENKE Chess Classic (2019) with 7.5/9 (+6 -0 =3) Another tournament Norway Chess (2019), another first 10.5/16 (+6 -1 =9). And as usual first, this time at GCT Croatia (2019), 8/11 (+5 -0 =6). Tied for first at Sinquefield Cup (2019) with Ding Liren, but then lost the tiebreaker with him =2 -2. At Isle of Man Grand Swiss (2019) he only managed 3rd-8th.

<2020> In January, Carlsen took part once again at Tata Steel Masters (2020), taking second 8/13 to Caruana's impressive first place 10/13. In June, Carlsen he played the Clutch International (2020) where he won the eight-player event. Another eight-player event was Norway Chess (2020), where he won first with 19.5, a point ahead of Firouzja.

<2021
The year got off to a disappointing start for the year with a sixth place at Tata Steel Masters (2021), where the local heroes Jorden van Foreest and Giri won with 8.5/13.

Rapid:

Carlsen won the Glitnir Blitz Tournament in 2006 in Iceland. In September 2006 Carlsen placed 8th out of 16 participants at the World Blitz Championship (2006) in Rishon LeZion, Israel. In the blitz tournament associated with the Tal Memorial 2006, namely the Tal Blitz Cup, Carlsen scored 17½/34 points and placed 9th in a group of 18 participants. In March 2007, Carlsen played for the first time in the Melody Amber blind and rapid chess tournament in Monte Carlo. In the 11 rounds of the 16th Amber Tournament (Blindfold) (2007), he achieved eight draws and three losses (placing =9th) then scored three wins, seven draws and one loss in the 16th Amber Tournament (Rapid) (2007) (=2nd), for an overall 8th place in the combined tournament. In March 2008, Carlsen played for the second time in the Melody Amber blind and rapid chess tournament, which was held in Nice for the first time. Carlsen achieved four wins, four draws and two losses in the Amber Tournament (Blindfold) (2008), and three wins, two losses, and six draws in the Amber Tournament (Blindfold) (2008), resulting in a shared second place in the overall tournament.

In the Chess Classic Mainz (2008), Carlsen finished in second place after losing the final to defending champion Anand 3:1 (two losses, two draws). In 2009, Carlsen scored equal first in the Amber Tournament (Blindfold) (2009) with 7/11 alongside Kramnik and Aronian, and equal second with Veselin Topalov at M-Tel Masters (2009) behind Shirov with a 2822 performance. He also won the XXII Magistral Ciudad de Leon (2009), a rapid knockout tournament, ahead of Morozevich, Ivanchuk, and Yue Wang. Just a few days after his 2nd placement at the Tal Memorial (2009), he won the World Blitz Championship (2009) with 31/42, a full three points ahead of runner-up Anand. He shared first place at the 2010 Amber Rapid and Blindfold Tournament with Ivanchuk; scoring 6½ points in the blindfold and 8 points in the rapid, Carlsen accumulated 14½ from a possible 22 points. After a slow start in the Arctic Securities Chess Stars (2010) rapid tournament, he continued his success by defeating Anand in the two-game playoff for gold. In the World Blitz Championship (2010), held in Moscow on 16â€"18 November, Carlsen attempted to defend his 2009 title. With a score of 23½/38, he finished in third place behind Radjabov and the winner Aronian. After the tournament, Carlsen played a private 40-game blitz match against Hikaru Nakamura, winning with a score of 23½â€"16½. A phenomenal 9.5/11, 2.5 points clear of the field, in 20th Amber Tournament (Rapid) (2011) was insufficient for him to win the overall contest, as his results in the 20th Amber Tournament (Blindfold) (2011) were poor, resulting in a 2nd overall to 2008 and 2009 overall winner Aronian. In July 2012 he came clear 2nd in the World Rapid Championship (2012) behind Karjakin with 10.5/15, and clear 2nd in the World Blitz Championship (2012) with 19.5/30, half a point behind Alexander Grischuk.

In June 2014, he realized his ambition to be the triple champion (of standard, rapid and blitz chess) when he won the World Rapid Championship (2014) with 11/15, half a point ahead of runner-up Caruana, and the World Blitz Championship (2014) with 17/21, one point clear of Nepomniachtchi and Nakamura. In October 2015, he successfully backed up to defend his title at the World Rapid Championship (2015), scoring 11.5/15, a point clear of runners-up Leinier Dominguez Perez, Teimour Radjabov and Ian Nepomniachtchi. Carlsen was second in the Paris Grand Chess Tour, placing second to Nakamura in the Grand Chess Tour Paris Rapid (2016) and equal first in the Grand Chess Tour Paris Blitz (2016) alongside Nakamura to take second place behind the US grandmaster. Soon afterward, he was overall first in the Leuven legs of the Grand Chess Tour, having won both the Your Next Move (Rapid) (2016) and the Your Next Move (Blitz) (2016). Carlsen won his final event before the upcoming Carlsen - Karjakin World Championship Match (2016) in New York, when he won the final of the Carlsen - Nakamura Chess.com Blitz Battle (2016) against Hikaru Nakamura. Carlsen obtained a large lead after the 5m+2spm and 3m+2spm sections and narrowly lost the bullet 1m+1spm with a final score of 14.5-10.5.

Carlsen placed equal first with 11/15 alongside Ivanchuk and Grischuk at the World Rapid Championship (2016), but placed third on countback. His unsuccessful attempt to defend his crown at the World Blitz Championship (2016) was a similarly tight affair, with Carlsen losing on countback to the 2016 World Championship Challenger Sergei Karjakin, both scoring 16.5/21. The following year in 2017, Carlsen won both the Paris and Leuven legs of the Grand Chess Tour of 2017 to lead the competition ahead of the Sinquifield and London legs to be staged later in 2017: he won the Grand Chess Tour Paris (Rapid) (2017) with 7/9 ahead of Grischuk and backed up with equal fourth at the Grand Chess Tour Paris (Rapid) (2017) to win the Paris leg on aggregate. At Leuven, Carlsen was third with 5.5/9 at the Your Next Move (Rapid) (2017) and clear winner by four points at the Your Next Move (Blitz) (2017) to take out the Leuven leg on aggregate.

Carlsen regained his blitz title at Riyadh in Saudi Arabia when he won the World Blitz Championship (2017) with a round to spare after the disappointment of losing the lead in the World Rapid Championship (2017) when he lost the last round.

At the World Rapid Championship (2018) he tied 2nd-5th with 10.5/15 (+9 -3 =3)Then at the World Blitz Championship (2018) he managed clear first 17/21 (+13 -0 =8). And oce again at Grand Chess Tour Cote d'Ivoire (Rapid & Blitz) (2019) took first 19/27 (+13 -2 =12) One and one half points ahead of the field. No surprise at Lindores Abbey Chess Stars (2019) where he took first 3.5/6 (+1 -0 =5) in the four player field. He only managed 6th at GCT St. Louis Rapid & Blitz (2019) finishing with a minus score 13/27 (+9 -10 =8) He took part in World Blitz Championship (2019) where he tied with Nakamura for first, both with 16.5/21 (+13 -1 =7). There were many online rapid and blitz events in 2020 and 2021, with Magnus winning his fair share.

Mar-10-17  Petrosianic: Why "only" <7 consecutive matches>?

Because Lasker retained in 6.

Mar-10-17  Olavi: Technically, as E. Winter will not tire to point out (missing the point as usual), Lasker retained in only five.
Mar-10-17  WorstPlayerEver: Oh well, but Magnus is king.
Mar-10-17  Petrosianic: Because the second 1909 match wasn't a championship match? Okay, then that makes Carlsen's job easier.

At least under the Most Retentions criteria. If we count Games Won in Championship Matches, then he'll never come close.

Mar-13-17  morebream: Very unlikely Magnus will remain WC till anything like 2040.

Look at this graph of his rating history compared to Wesley So: http://www.chessgraphs.com/?name%5B...

Carlsen's been on a plateau for the past four years while So is climbing fast and will take the title from Magnus soon, I predict.

Mar-14-17  wordfunph: I think Magnus is already at the summit of the mountain and all the rest looks like they are climbing fast but will just get kicked downhill once they try to show their faces at the top
Mar-14-17  tuttifrutty: <Carlsen's been on a plateau for the past four years while So is climbing fast and will take the title from Magnus soon, I predict.>

It has been prophesied, the chess messiah is here to don the crown. Mangus is all downhill from here on....

<all the rest looks like they are climbing fast but will just get kicked downhill once they try to show their faces at the top>

Except Wesley who will overtake Magnus all time record by the end of this year, then leap to 3000 and beyond for all the world to see.

Mar-14-17  lentil: <morebream> 1: extrapolation is error-prone; 2: the person with the highest rating has the hardest time increasing it.

  OhioChessFan: I admit to being enough of a geek I looked at the So-Carlsen graph before the pics of Maggie's gf.
Mar-23-17  Jambow: <OCF> I did too :0(
Mar-23-17  Jambow: Well that being said perhaps So will over take Carlsen if his attention is divided.

In all honesty if Carlsen has actually reached his peak then So is looking like he has a real shot, however I think Magnus has been playing below his best chess and if he plays at even his former level at this end of the scale the bar raises where it is most difficult to gain. I have always felt it will be a player that understands Magnus himself that is needed, similar to Kramnik defeating Kasparov etc...

I'm a fan of both players and I was sorta rooting for Magnus to break 2900 elo just because it is a nice milestone.

It is good for challengers to emege for empires and kings to rise etc... I'm still watching Caruana too.

  AylerKupp: A Pilgrim's Progress (Part 1 of 4)

<Sally Simpson> in US Championship (2017) (kibitz #244) asked the following question: If Carlsen's grade was set to zero and all he played was under 2000 players he would still be the best player on the planet but it would take him x number of years at 50 games a year to get to 2800. So, under the category of "be careful what you ask for", here hopefully is the answer.

First, some guidelines, assumptions, and simplifications:

1. Method. I used the current FIDE Rating Regulations as listed in https://www.fide.com/fide/handbook..... Just remember that I'm just the messenger and I didn't make these rules, nor was I consulted about them!

2. Carlsen's actual playing strength is the equivalent of a 2800+ rating. I think that this is what you meant since, if Carlsen's actual playing strength was below the equivalent 2800, he shouldn't achieve a rating of 2800, assuming that the rating calculations are anywhere near correct. That's another big assumption.

3. Carlsen's initial rating is not zero. Under the current FIDE rating regulations a zero rating might not be possible because, assuming that Carlsen is unrated when he plays in his first tournament, if an unrated player scores zero in his first rated event, his score is disregarded. So I'm not sure if a player's rating could ever be zero since they would first have to get a rating greater than zero and then would have to lose enough games to drive their rating to zero. But FIDE's current rating floor is 1000 so, assuming that Carlsen's initial rating was over 1000, I don't think that he could never get below 1000 since his rating would no longer be published. So presumably he would simply become unrated again. But someone should verify this.

4. Carlsen plays his first rated game when he's at least 18 years old. This simplifies the calculations some more since you then don't have to take into account the K factor (see below) = 40 for all players until their 18th birthday as long as their rating remains under 2300. If Carlsen's first rated game occurs before he turns 18, then the ratings calculations use K = 40 until his rating reaches 2300. In actuality, Carlsen first broke the 2300 rating threshold (and never looked back) in the Apr-2003 rating list when he was 12 years old.

5. So let's assume for reality (not that this matters all that much in this analysis) that Carlsen's initial rating is 1000. If he always plays opponents rated below 2000, that means that his opponents must be rated between 1000 and 1999. For simplicity and probably representing best case (fastest way to increase his rating), assume that each of his opponents is rated 1999. Therefore the average rating of his opponents is also 1999. (continued)

6. Since ratings are calculated at the end of each tournament or match and Carlsen is to play 50 games per year, let's assume that he plays in 5 round robin tournaments of 11 players each so that he plays 10 games in each tournament. That's also a convenient simplification because tournaments typically have an even number of players in order to avoid giving a bye to one player each round. And because at a rating of 1000 he is "somewhat" underrated, and to simplify the calculations, let's assume that Carlsen always wins his games. A not entirely unreasonable assumption given that with at least an actual 800 point rating advantage over his opponents, the FIDE scoring probability tables indicate a probability of winning <or> drawing a game [ P(W or D) ] to be 1.0 for a rating differential of > 735 points. In reality there's always a possibility, however small, that he might draw or even lose his game (blunders happen to even the best player), but the probability of that happening is reasonably small to be ignored, at least for the first attempt at coming up with an answer.

7. Since Carlsen starts out as unrated, the first order of business is to establish his initial rating. Per Section 8.2 of the FIDE Rating Regulations and the assumptions above, the rating after his first tournament is given by Ru = Ra + 20 for each half point scored over 50%, where Ru is the initial rating of the unrated player and Ra = Rar – dpa * n/(n-1) where

Rar = Average rating of each player = 1999 in this case since the assumption is that's the rating of each player.

dpa = Average P(W or D) when each opponent plays each other (excluding Carlsen) = 0 since in this case each player is rated the same and so their rating difference is zero.

n = Number of opponents = 10. But in this case it doesn't matter since dpa = 0 so dpa * n/(n-1) is also = 0.

So Ra = Rar = 1999. Since Carlsen wins all his games he gets 20 points for each half point scored over 50% or 40 points for each win over 5 in a 10-round tournament. Therefore Carlsen's rating after his first tournament would be Ru = 1999 + 5 wins * 40 points/win = 2199. Not a bad start in the goal to reach 2800!

8. Now that Carlsen has a rating a rating change is calculated after each subsequent tournament and added to his rating prior to the start of the tournament. His new rating after his second tournament would be calculated as (R(n) is his rating after his nth tournament):

R(2) = R(1) + K* Ó [ score – P(W or D) ]

R(2) = R(1) + K * 10*[ score – P(W or D) ] since there are 10 opponents and all the P(W or D)s are the same.

R(2) = 2199 + K*10*(1-0.63) since P(W or D) for a rating difference of 200 points = 0.63 and Carlsen always wins so his score for each game = 1.

R(2) = 2199 + K*3.7

K is the "K factor" and is = 40 until a player has completed events with at least 30 games. So Carlsen's rating after his second tournament would be R(2) = 2199 + 40*3.7 = 2347. (continued)

9. His rating after his third tournament would be calculated similarly. His new P{W or D) for a rating difference of 2347 – 1999 = 348 would be 0.89. So Carlsen's rating after his third tournament would be:

R(3) = R(2) + K*10*(1 – 0.89) = 2347 + 40*10*0.11 = 2391

10. His rating after his fourth tournament would be calculated similarly except that K = 20 is used since he would have played 30 games AND his rating is still below 2400. His new P{W or D) for a rating difference of 2391 – 1999 = 392 would be 0.92. So Carlsen's rating after his fourth tournament would be:

R(4) = R(3) + K*10*(1 – 0.91) = 2391 + 20*10*0.09 = 2409

11. His rating after his first tournament would be calculated similarly except that:

(a) His rating is over 2400 so K = 10 is used.

(b) His rating differential over his opponents (2409 – 1999) is over 400 points so for the purposes of rating calculations the "Rule of 400" indicates that a rating differential of 400 points is used and P(W or D) = 0.92. So Carlsen's rating after his fifth tournament would be:

R(5) = R(4) + K*10*(1 – 0.92) = 2409 + 10*10*0.08 = 2417.

Therefore, after the first year and the first 50 games played, Carlsen's rating would have reached 2417.

12. Subsequent rating changes would use the same K = 10 since, once a player's rating reaches 2400, K= 10 is always used, and P(W or D) = 0.92 since, if he keeps winning, his rating keeps increasing, although at an ever reduced rate, and his rating differential would always be 400 points for the rating calculations. So, for subsequent years we have a constant increase of 10*10*.08 = 8 rating points per tournament or 40 rating points/year if he plays in 5 10-round tournaments:

R(6) = R(5) + 10*10*(1 – 0.92) = 2417 + 8 = 2425

R(7) = R(6) + 10*10*(1 – 0.92) = 2425 + 8 = 2433

R(8) = R(7) + 10*10*(1 – 0.92) = 2433 + 8 = 2441

R(9) = R(8) + 10*10*(1 – 0.92) = 2441 + 8 = 2449

R(10) = R(9) + 10*10*(1 – 0.92) = 2449 + 8 = 2457

Therefore, Carlsen would not reach 2800 until after he had played in (2800 – 2457)/8 = 43 additional tournaments which, at a rate of 5 tournaments /year, would take him approximately another 8.5 years or until he had finished playing in his 53rd tournament. So, under the current FIDE Rating Regulations, if Carlsen (or anyone else) was unrated and 18 years old at the time of his first tournament, it would take him about 11.5 years to reach 2800 under the "somewhat" unrealistic assumptions above. And this is the best that he or anyone else could do given the assumptions and simplifications I made. And also assuming, of course, that my understanding of the FIDE Rating Rules is correct and that all my calculations above are also correct. Two very big IFs.

So, if anyone is willing to check my understanding of the FIDE rating rules and my calculations, I would greatly appreciate it. (continued)

As reality check, Carlsen's first published rating was 2064 in Apr-2001 when he was about 10 1/2 years old. He reached 2800 (2801) in Nov-2009, although he came very close (2786) more than a year earlier (Oct-2008). He was about 19 1/2 years old when he reached 2800 and it took him almost 9 years to go from 2064 to 2801.

Next, I'll try to make some of the assumptions a little bit more realistic and reduce the number of simplifications and see what happens. Two simplifications to correct immediately come to mind:

1. The assumption that Carlsen would win every game because of the large disparity in ratings between him and his opponents. Even though is what the ratings differentials predict, a 550 game winning streak is difficult to swallow, even against much weaker competition. So perhaps the calculations should be repeated with a P(W or D) < 1.0 and see what this predicts, particularly since a loss or even a draw would result in a huge reduction in his ratings change.

2. The assumption that each of his opponents is rated 1999 is also not realistic. The Apr-2017 FIDE rating list contains 154,614 active players with 123,107 of them rated < 2000. So, if a below-2000 opponent is selected at random, his/her rating will be somewhat less than 1999. The result would be that the Rule of 400 would come into effect earlier and Carlsen's rating should increase faster. But how much faster is unknown.

Other interesting things to explore:

1. The impact of an initial rating obtained at an early age. This should also result in an increase in the rate of rating increase since a K-factor of 40 would be used longer.

2. The impact of the Rule of 400. This results in a ratings increase of 8 points for each win as a result of the P(W or D) to be clamped at 0.92. If the Rule of 400 did not exist, P(W or D) would be higher and the ratings increase per won game smaller.

Each of these changes and explorations will require a more sophisticated spreadsheet than the one I threw together and will have to wait until I have more time. Not anyone is holding their breath for the results.

See? I told you to be careful what you asked for.

  Sally Simpson: Phew! Thanks AylerKupp,

it was a discussion about was is regarded as best The World Champion or the current highest rated player.

I go for the World Champion, grades are based on who you have played and their grade. To get to be World Champion you have play better against some pretty good players and then knock over the Champion themselves.

Showing by maths, 11½ years (I thought it would be longer) to get to over 2800 by using 2000 players kind of proves the point as you cannot use maths to create a World Champion. Games have to be played against some very good players. Getting to the final is an achievement in itself.

Of course being number one on the rating list means you have beaten some very good players but as Petrosianic mentioned. You could sit on your rating for a year and if those above you have a bad spell you could get to number without pushing a pawn.

  AylerKupp: <Sally Simpson> You could sit on your rating for a year but if you do that that will not help you qualify for the 2018 Candidates Tournament on the basis of rating, as Caruana is apparently trying to do. The 2018 Candidates qualification rules require that you play at least 30 games during the 12 months (probably 3 tournaments) used to calculate your rating for the purpose of qualifying AND play in either the 2017 World Cup or the 2017-2018 Grand Prix tournaments.

And in order to achieve a #1 ranking by sitting on your rating, all those players who were initially ranked ahead of you must lose rating points by losing to other players. And who would these other players be that they defeat all the top-ranked players? Most likely they are other top players. So it's not likely that <all> top players have a bad year.

As far as your discussion is concerned I would vote for the #1 player. Of course, you have to be a pretty good player in order to become either World Champion or Challenger. But anyone can have a bad tournament or match, particularly if they are short. So, if the World Champion is ranked #1 and has a bad match (think Tal in 1961), then it's possible for the Challenger to become World Champion even though he's not the best player. The ratings take a much greater number of games into account and therefore I think that they're a better predictor of who is the better player. The one thing that a match tells you is which of two players was the better player during the time that the match was conducted.

  Sally Simpson: HI AylerKupp,

I did mention you must play in the preceding year to get into the candidates, although there is always the wildcard.

The question was what would you rather be. World Champion or Number one on the rating list. I think most would be World Champion.

As always with these forums debates it went off at right angles as to who was the better player.

The fact that at the moment Carlsen is the World Champion and Number One on the rating list shows how silly these debates can become....I love taking part in them!

  AylerKupp: A Pilgrim's Progress – The Sequel (part 1 of 2)

In case anyone still cares, I've refined my spreadsheet and can now do some "what if" analyses. But first let me correct my earlier statement about Carlsen (or anyone else) being able to reach 2800 in 11 1/2 months. I made 2 mistakes (that I know of) in my earlier calculations:

1. My dyslexia is getting worse as I age so I looked in the wrong column in the FIDE Scoring Probability table, mistaking 0.63 for 0.85 as the P(W or D) for a rating differential of 200 points in Carlsen's 2nd tournament. As a result, his rating at the end of his second tournament should have been 2295 instead of 2347.

2. When coding the K-Factor calculation as a function (as opposed to a formula) I saw that I had used a ">" rather than a ">=" condition in the formula. As a result, I used K = 40 instead of K = 20 in calculating Carlsen's rating after his third tournament. So Carlsen's rating at the end of his third tournament should have been 2325 instead of 2391.

The result is actually not that significant. Instead of 11 1/2 months to reach 2800 (the third tournament in the 11th year) it would take Carlsen 12 years to reach 2800 (the first tournament in the 12th year).

So for some more "reality injections":

1. I had originally specified that, to simplify the calculations, Carlsen's played in his first tournament when he was 18, and I hypothesized that if he started earlier he could reach 2800 faster because his K-factor would be 40 until he either was 18 years old or reached 2300. I was technically right, but not by much, because he reached 2300 so quickly. Carlsen's first rated tournament was when he was 10 1/2 years old but this rule only accelerated his achieving 2800 by one month; i.e. the last tournament of his 11th year. Still, I used a starting age of 10 1/2 for all the subsequent calculations.

2. Another observation was the assumption that Carlsen would win every game because of the large discrepancy between his actual playing strength (the equivalent of 2800+) and his opponents ratings. Still, an 11 3/4-year, 550 game winning streak is hard to envision. So, if instead of winning each game he "allowed" one draw per tournament (Win % = 95%), this would add only a little bit more than 6 months (after the fourth tournament of his 12th year) to reach 2800. And "allowing" either 2 draws or a loss in each tournament (Win % = 90%) would delay his reaching 2800 an additional 3 months, until after his second tournament of the 13th year.

3. Assuming that each of Carlsen's opponent would be rated 1999 is obviously pessimistic in respect to seeing how quickly Carlsen could reach 2800; their average rating would clearly be lower. I mentioned in my earlier long (what else from me?) discourse that The Apr-2017 FIDE rating list contains 154,614 active players with 123,107 of them rated < 2000. I calculated the player rating distribution and its mean before smoothing was 1756, with 203 players having that rating. Smoothing the playing distribution by using a 4th degree polynomial yielded a reasonably good fit (R2 = 0.9180) with its mean roughly 1820. And using 1820 for an average opponent's rating and the "reality injections" above (starting age 10 1/2 and 9/10 score in each tournament) results in Carlsen reaching 2800 in approximately 14 1/2 years, after the second tournament of his 14th year.

At the other extreme, if each of Carlsen's opponents were rated 1000, then it would take Carlsen approximately 20 1/2 years to reach 2800, or after the third tournament of his 20th year. So, according to the FIDE rating rules and under the "reality injections" above, it would take Carlsen between 13.2 years (average opponent rating = 1999) and 20.6 years (average opponent rating 1000), with the most likely time being 14.8 years (average opponent rating 1820).

So let's break some rating rules, specifically the Rule of 400. Initially the Rule of 350, it was proposed by Anand in the mid 2000s because he did not want to lose a large number of rating points in open tournaments if he happen to simply stumble against a much lower-rated opponent. This was adopted by FIDE for the Apr-2006 rating list and revised to the Rule of 400 for the Jul-2009 rating list. Given the relatively small number of open tournaments vs. closed tournaments that top-level players play in, I doubt that there ever was a large impact on top level players (other than their pride) in losing to a much lower-rated player.

The consequence of deleting the Rule of 400 is tremendous in this case. With the Rule of 400 in effect, Carlsen would win at least 8 rating points per tournament if his average tournament score was 10.0 points or 9.5 points and at least 7 rating points per tournament if his average tournament score was 9.0 points. This is because the FIDE Rating Regulations (section 8.57) indicate that the rating increment should be rounded up to the nearest 0.5 points.

But with the Rule of 400 eliminated Carlsen's rating increment per tournament goes down steadily until it reaches only 1 point somewhere during the 9th year regardless of whether his average tournament score is 10.0, 9.5, or 9.0 points per tournament. This results in Carlsen requiring more than 80 years (!) to reach 2800 instead of the 14.8 years if the Rule of 400 remains in effect. Quite a difference.

Therefore I don't think that any greatly underrated unrated players would be in favor of eliminating the Rule of 400!

I can't imagine why, but if anyone is interested in looking at and playing with the spreadsheet you can download it from here: http://www.mediafire.com/file/7d5cm....
