Game length records
The longest tournament chess game (in terms of moves) ever to be played was Nikolić–Arsović, Belgrade 1989, which lasted for 269 moves and took 20 hours and 15 minutes to complete a drawn game. At the time this game was played, FIDE had modified the fifty-move rule to allow 100 moves to be played without a piece being captured in a rook and bishop versus rook endgame, the situation in Nikolić versus Arsović. FIDE has since rescinded that modification to the rule.
The longest decisive tournament game is Danin–Azarov, Turnov 2016, which Danin won in 239 moves. In the 9th round of THT Extraliga (highest Czech team league), Danin needed to win his game to make the match end in a 4:4 draw. Although he managed to do that, his team (TŽ Třinec) was relegated from the highest league in the end.
The second longest decisive tournament game is Fressinet–Kosteniuk, Villandry 2007, which Kosteniuk won in 237 moves. The last 116 moves were a rook and bishop versus rook ending, as in Nikolić – Arsović. Fressinet could have claimed a draw under the fifty-move rule, but did not do so since neither player was keeping score, it being a rapid chess game. Earlier in the tournament, Korchnoi had successfully invoked the rule to claim a draw against Fressinet; the arbiters overruled Fressinet's argument that Korchnoi could not do so without keeping score. Fressinet, apparently wanting to be consistent, did not try to claim a draw against Kosteniuk in the same situation.
Shortest decisive game
The fewest number of moves required to deliver checkmate in chess is two, in what is known as Fool's mate (1. g4 e5 2. f3?? Qh4# and variants thereof). This has been known to occur in amateur play. Chessgames.com gives a game L. Darling–R. Wood, 1983, that was published on April Fool's Day in Northwest Chess magazine (1. g4 e6 2. f4?? Qh4#). Bill Wall lists, in addition to Darling–Wood, three other games that ended with Black checkmating on the second move. In a tournament game at odds of pawn and move, White delivered checkmate on move 2: W. Cooke-"R____g", Cape Town Chess Club handicap tournament 1908 (remove Black's f-pawn) 1. e4 g5?? 2. Qh5#. The same game had previously been played in Leeky-Mason, Dublin 1867.
If one counts forfeited games as a loss in zero moves, then there have been many such forfeits, the most notable examples being Game 2 of the 1972 world championship match between Boris Spassky and Bobby Fischer, which Fischer defaulted, and Game 5 of the 2006 world championship match between Vladimir Kramnik and Veselin Topalov, which Kramnik defaulted.
Under recently instituted FIDE rules, a player who is late for the beginning of a round loses the game, as does a player whose cellphone makes any sound in the tournament hall. The former rule was used at the 2009 Chinese Championship to forfeit Hou Yifan for arriving five seconds late for the beginning of a round. The latter rule was used to forfeit Aleksander Delchev against Stuart Conquest after the move 1.d4 in the 2009 European Team Championship.
The German grandmaster Robert Hübner also lost a game without playing any moves. In a World Student Team Championship game played in Graz in 1972, Hübner played one move and offered a draw to Kenneth Rogoff, who accepted. However, the arbiters insisted that some moves be played, so the players played the following ridiculous game: 1. c4 Nf6 2. Nf3 g6 3. Ng1 Bg7 4. Qa4 0-0 5. Qxd7 Qxd7 6. g4 Qxd2+ 7. Kxd2 Nxg4 8. b4 a5 9. a4 Bxa1 10. Bb2 Nc6 11. Bh8 Bg7 12. h4 axb4 (draw agreed). The arbiters ruled that both players must apologize and play an actual game at 7 p.m. Rogoff appeared and apologized; Hübner did neither. Hübner's clock was started, and after an hour Rogoff was declared the winner. Wang Chen and Lu Shanglei both lost a game in which they had played no moves. They agreed to a draw without play at the 2009 Zhejiang Lishui Xingqiu Cup International Open Chess Tournament held in Lishui, Zhejiang Province, China. The chief arbiter declared both players to have lost the game.
More rarely, a player might decide to protest by resigning a game rather than forfeiting. A game between Fischer and Oscar Panno, played at the Palma de Mallorca Interzonal 1970, went 1. c4 Black resigns. Panno refused to play to protest the organizers' rescheduling of the game to accommodate Fischer's desire not to play on his religion's Sabbath. Panno was not present when the game was to begin. Fischer waited ten minutes before making his move and went to get Panno to convince him to play. Fifty-two minutes had elapsed on Panno's clock before he came to the board and resigned. (At the time, an absence of sixty minutes resulted in a forfeit.)
The shortest decisive tournament game that was decided because of the position on the board (i.e. not because of a forfeit or protest) is Z. Đorđević–M. Kovačević, Bela Crkva 1984. It lasted only three moves (1.d4 Nf6 2. Bg5 c6 3.e3?? Qa5+ winning the bishop), and White resigned. This was repeated in Vassallo-Gamundi, Salamanca 1998. (In a number of other games, White has played on after 3...Qa5+, occasionally drawing or even winning in this line.) The shortest game ever lost by a grandmaster because of the position on the board was by future world champion Viswanathan Anand, who resigned on move 6 against Alonso Zapata in 1988 (1. e4 e5 2. Nf3 Nf6 3. Nxe5 d6 4. Nf3 Nxe4 5. Nc3 Bf5?? 6. Qe2 winning a piece, since 6...Qe7 is answered by 7.Nd5 Qe6? 8. Nxc7+).
A game may be drawn by mutual agreement in any number of moves. Traditionally, it has been common for players to agree a "grandmaster draw" after playing about 10-15 moves of known opening theory and making no serious effort to win. This is usually done to preserve energy in a tournament, after a devastating loss in the previous round of the tournament, or in the final round when no prize money is at stake. There has been some debate over the ethics of the practice, and recently there has been a trend away from such games, with many tournaments adopting measures to discourage short draws. If the tournament officials (unlike those at Graz and Lishui) do not object, a game may even be agreed drawn without a single move being played. According to ChessGames.com, in the 1968 Skopje–Ohrid tournament Dragoljub Janosevic and Efim Geller agreed to a draw without playing any moves. Tony Miles and Stewart Reuben did the same thing in the last round of the Luton 1975 tournament, "with the blessing of the controller", in order to assure themselves of first and second places respectively.
Shortest World Championship game
As mentioned above, Fischer (in 1972) and Kramnik (in 2006) each forfeited a world championship game without playing any moves. Other than those unplayed games, the shortest game in a world championship was the 21st match game in the World Chess Championship 1963 between Mikhail Botvinnik and Tigran Petrosian. The players agreed to a draw after the 10th move by White (Petrosian). The shortest decisive, non-forfeited world championship game occurred between Viswanathan Anand and Boris Gelfand in game 8 of the World Chess Championship 2012. Gelfand resigned after Anand's 17th move, 17.Qf2.
The shortest composed stalemate, devised by Sam Loyd, involves the sequence 1.e3 a5 2.Qh5 Ra6 3.Qxa5 h5 4.Qxc7 Rah6 5.h4 f6 6.Qxd7+ Kf7 7.Qxb7 Qd3 8.Qxb8 Qh7 9.Qxc8 Kg6 10.Qe6. The shortest stalemate with all of the pieces on the board, composed by Charles H Wheeler, occurs after 1.d4 d6 2.Qd2 e5 3.a4 e4 4.Qf4 f5 5.h3 Be7 6.Qh2 Be6 7.Ra3 c5 8.Rg3 Qa5+ 9.Nd2 Bh4 10.f3 Bb3 11.d5 e3 12.c4 f4 (minor variations are possible). These games are nonsensical from the point of view of chess strategy, but both have occasionally been played in tournaments as a joke, as part of a prearranged draw. The shortest known route to a position where both players are stalemated, discovered by Enzo Minerva and published in the Italian newspaper l'Unità on 14 August 2007, is 1.c4 d5 2.Qb3 Bh3 3.gxh3 f5 4.Qxb7 Kf7 5.Qxa7 Kg6 6.f3 c5 7.Qxe7 Rxa2 8.Kf2 Rxb2 9.Qxg7+ Kh5 10.Qxg8 Rxb1 11.Rxb1 Kh4 12.Qxh8 h5 13.Qh6 Bxh6 14.Rxb8 Be3+ 15.dxe3 Qxb8 16.Kg2 Qf4 17.exf4 d4 18.Be3 dxe3. The shortest genuine stalemate in a serious game was played in Ravenna 1982, when the Italian master Mario Sibilio forced a stalemate on move 27 against grandmaster Sergio Mariotti.
Fewest moves played in a tournament
Latest first capture
In Rogoff–Williams, World Junior Championship, Stockholm 1969, the first capture (94.bxc5) occurred on White's 94th move. Filipowicz–Smederevac, Polanica Zdroj 1966, was drawn in 70 moves under the fifty-move rule, without any piece or pawn having been captured.
Latest first capture in a decisive game

Largest number of helpless pinned pieces
In the final position of G. Chandler–R. Kynoch, Edinburgh Club Championship 1981, White's knight on f6 administered checkmate with three black pieces capable of capturing it, except that all three could not do so because they were pinned against Black's king.
The book 1000 TN!! The Best Theoretical Novelties contains the games with the ten highest-ranked theoretical novelties (TNs) that appeared in each of Volumes 11 through 110 of Chess Informant. The earliest such novelty occurred on White's fourth move in Karpov-Miles, Bugojno 1978, namely 1.c4 b6 2.d4 e6 3.d5 Qh4 4.Nc3! The latest occurred on Black's 34th move (34...Kd5!) in Shulman-Marin, Reykjavík Open 2009. The only game to receive a perfect rating from Chess Informant's panel of judges was Miles-Belyavsky, Tilburg 1986, which featured the novelty 18.f4!! It received 90 points, 10 out of a possible 10 from each of the 9 judges.
Following the breakup of the Soviet Union, Russia has continued to hold the record for greatest number of grandmasters. In the January 2016 rating list, 217 of the 1506 grandmasters were from Russia.
Greatest concentration of resident grandmasters
In 2005, Reykjavík, Iceland, with eight grandmasters (Jon Arnason, Jóhann Hjartarson, Margeir Petursson, Fridrik Olafsson, Throstur Thorhallsson, Helgi Gretarsson, Hannes Stefansson, and Bobby Fischer) had a higher percentage of resident grandmasters per capita than any other city worldwide; the city of 114,000 had, therefore, one grandmaster per 14,000 residents.
Perfect tournament and match scores
In top-class chess it is rare for a player to complete a tournament or match with a 100 percent score. This result was however achieved in tournaments by:
- Gustav Neumann at Berlin in 1865 (34/34)
- William Pollock at Belfast 1886 (8/8)
- Emanuel Lasker at New York in 1893 (13/13)
- Henry Atkins at Amsterdam 1899 (15/15)
- José Raúl Capablanca at New York in 1913 (13/13, including one default)
- David Janowski at Paris in 1914 (9/9)
- Alexander Alekhine at Moscow in 1919–20 (11/11)
- Boris Kostić at Hastings 1921–22 (7/7)
- Bobby Fischer at the US Championship of 1963/64 (11/11)
- Alexander Beliavsky at Alicante in 1978 (13/13)
- Sandro Mareco at Montevideo in 2017 (9/9)
Perfect scores were achieved in matches by:
- Howard Staunton over Daniel Harrwitz in 1846 (7/7)
- Wilhelm Steinitz over Joseph Henry Blackburne in 1876 (7/7)
- Capablanca over Kostić in 1919 (5/5)
- Fischer over Mark Taimanov in 1971 (6/6) (quarter-final Candidates Match)
- Fischer over Bent Larsen in 1971 (6/6) (semi-final Candidates Match)
William Lombardy is the only player ever to achieve a perfect score in the World Junior Chess Championship, open to players under the age of 20 as of January 1 in the year of competition. He scored 11–0 at Toronto 1957.
Vera Menchik won four consecutive Women's World Chess Championship tournaments with perfect scores, a total of 45 games (8–0 at Prague 1931, 14–0 at Folkestone 1933, 9–0 at Warsaw 1935, and 14–0 at Stockholm 1937). She only played 43 of the 45 games, since Harum, the Austrian contestant, was unable to reach Folkestone and thus forfeited all of her games in that double round robin event.
Alekhine scored 9–0 on first board for France at the 3rd Chess Olympiad (Hamburg, 1930), and Dragoljub Čirić scored 8–0 as second reserve (the sixth player on his team) for Yugoslavia at the 17th Olympiad (Havana, 1966), but each played only about half of the possible games. Robert Gwaze scored 9–0 on first board for Zimbabwe at the 35th Olympiad (Bled, 2002).
Wesley So scored 9/9 in the 2011 Inter-Provincial Chess Team Championship, with a performance rating of 3037, won the gold medal in men's blitz at the SEA Games 2011 at Indonesia with a score of 9/9 and a rating performance of 3183, and won the 2013 Calgary International Blitz Championship with a score of 9/9.
Consecutive tournament victories
Most tournament victories
Most wins in a national championship
As of November 2014, Carlos Juárez has won the national championship of Guatemala 25 times.
Most decisive Interzonal victory
The highest percentage score at an Interzonal was 82.5% (16½ points out of 20 games), scored by Alexander Kotov at the 1952 Stockholm Interzonal. The largest margin of victory was achieved by Bobby Fischer, who won the Palma de Mallorca Interzonal in 1970 with 18½ points out of 23 games, 3½ points ahead of second-place finishers Bent Larsen, Efim Geller and Robert Hübner.
Most games won
Gustav Neumann won all 34 of his games at the aforementioned Berlin 1865 tournament.
Most games lost
Nicholas MacLeod holds the record for the most games lost in a single tournament: he lost 31 games at the Sixth American Chess Congress at New York 1889, while winning six and drawing one. MacLeod was only 19, and the tournament, a 20-player double-round robin, was one of the longest tournaments in chess history. The most games lost by a player who lost all of his games in a tournament was by Colonel Moreau. At Monte Carlo 1903, Moreau lost all 26 of his games.
Lost all games on time
Most world champions in a tournament
Nottingham 1936 included five past, current, and future world champions: reigning champion Max Euwe; Alexander Alekhine, who had lost the title to Euwe the prior year, and would regain it the following year; former champions Emanuel Lasker and José Raúl Capablanca; and Mikhail Botvinnik, who would win the championship in 1948. This record was equaled by Moscow 1971 and the 1973 Soviet Chess Championship, each of which included former champions Vasily Smyslov, Mikhail Tal, and Tigran Petrosian; Boris Spassky, who was champion from 1969 to 1972; and future champion Anatoly Karpov.
Largest tie for first
Thirteen players tied for first with 5–1 scores at the National Open held on March 17–19, 2000 in Las Vegas: grandmasters Jaan Ehlvest, Alexander Goldin, Alexander Baburin, Pavel Blatny, Eduard Gufeld, Yuri Shulman, Alex Yermolinsky, Gregory Kaidanov, Dmitry Gurevich, Alexander Stripunsky, and Gregory Serper, and International Masters Rade Milovanovic and Levon Altounian.
Highest percentage of players below 50% in a tournament
At the Linares 2001 tournament, five of the six players (83.3%) finished with a minus score. Garry Kasparov won with 7½/10, while Judit Polgár, Alexander Grischuk, Peter Leko, Alexei Shirov, and Anatoly Karpov tied for second to sixth places, each with 4½/10.
Highest percentage of draws in a tournament
At the 1999 Petrosian Memorial tournament, 42 of the 45 games (93.3%) were drawn. Five of the ten players drew all nine of their games.
Highest performance rating in a tournament
- 3102, Fabiano Caruana, Sinquefield Cup 2014
- 3001, Magnus Carlsen, Pearl Spring 2009
- 2999, Gabriel Sargissian, Zafra 2007
Note: If one includes performances before the Elo rating system was established, then Emanuel Lasker's score of 13 out of 13 in the 1893 Tournament in New York has a Chessmetrics performance of 3190. The tournament was Category 12 and Lasker's rating at that point was 2749.
Consecutive wins against masters
Wilhelm Steinitz won his last 16 games at Vienna 1873, including a two-game playoff against Blackburne at the end. He played no serious chess until an 1876 match against Blackburne that Steinitz swept 7–0. After a long period of inactivity, Steinitz played at Vienna 1882, where he won his first two games before finally ending his winning streak with a draw. Steinitz's 25-game winning streak over nine years has never been equaled.
In modern times, Bobby Fischer won 20 consecutive games, all in competitions at late stages of the world championship cycle. (Some commentators give this as 19, electing not to count Fischer's game against Oscar Panno, who resigned after Fischer's first move as a protest). Fischer won his last seven games at the 1970 Palma de Mallorca Interzonal (including the one-move game against Panno), then swept Mark Taimanov 6–0 in the quarterfinals followed by Bent Larsen by the same score in the semifinals. In the Candidates Match final, Fischer beat former World Champion Tigran Petrosian in the first game before Petrosian snapped the streak by winning the second match game.
Consecutive games without a loss
Between October 23, 1973, when he lost to Tigran Petrosian in the 15th round of the Soviet championship, and October 16, 1974, when he lost to Nino Kirov at the Novi Sad tournament, Mikhail Tal had a string of 95 tournament games without a loss (46 wins and 49 draws). Tal also has the second-longest unbeaten run in top-level competition. He went unbeaten in 86 games from July 1972, when he lost to Gunnar Uusi in the tenth round at Viljandi, until April 1973, when he lost to Yuri Balashov in round two of the USSR Team Championship in Moscow. This streak included 47 wins and 39 draws.
Wilhelm Steinitz went 9 years without a loss (including his 25 consecutive win streak mentioned above), but the streak included only 32 games.
Most wins against world champions
Paul Keres, Viktor Korchnoi, and Alexander Beliavsky are the only chess players to have defeated nine undisputed world champions. They have four in common: all three defeated Vasily Smyslov, Mikhail Tal, Tigran Petrosian, and Boris Spassky. Keres also beat José Raúl Capablanca, Alexander Alekhine, Max Euwe, Mikhail Botvinnik, and Bobby Fischer; Korchnoi also beat Mikhail Botvinnik, Bobby Fischer, Anatoly Karpov, Garry Kasparov, and Magnus Carlsen; Beliavsky also beat Anatoly Karpov, Garry Kasparov, Vladimir Kramnik, Viswanathan Anand, and Magnus Carlsen. In addition, Korchnoi defeated FIDE world champions Ruslan Ponomariov and Veselin Topalov while Beliavsky defeated FIDE world champion Alexander Khalifman. If draws are included, Korchnoi has a unique distinction as the only player to have beaten or drawn every undisputed world chess champion and every disputed world champion since the interregnum of WWII, as he has drawn FIDE world champion Alexander Khalifman and undisputed world champions Vladimir Kramnik and Viswanathan Anand.
If disputed world champions are included, then Garry Kasparov shares Korchnoi's record of 11. Kasparov has defeated seven undisputed world champions (Smyslov, Tal, Petrosian, Spassky, Karpov, Kramnik, Anand) as well as four FIDE world champions (Khalifman, Ponomariov, Rustam Kasimdzhanov and Topalov).
The highest rating ever achieved is 2882, by Magnus Carlsen on the May 2014 list.
Progression of highest rating record Player Rating Year-month first achieved Bobby Fischer 2760 1971-01 Bobby Fischer 2785 1972-01 Garry Kasparov 2800 1990-01 Garry Kasparov 2805 1993-01 Garry Kasparov 2815 1993-07 Garry Kasparov 2820 1997-07 Garry Kasparov 2825 1998-01 Garry Kasparov 2851 1999-07 Magnus Carlsen 2861 2013-01 Magnus Carlsen 2872 2013-02 Magnus Carlsen 2881 2014-03 Magnus Carlsen 2882 2014-05
Carlsen also holds the highest unofficial "live rating" of 2889.2, achieved on April 21, 2014.
Largest rating lead
On the July 1972 FIDE rating list, Bobby Fischer's rating of 2785 was 125 points ahead of the second-highest rated player, then-reigning World Champion Boris Spassky (2660). Kasparov's biggest lead at his peak was 82 points in January 2000. There was a point in the early 1990s when Kasparov was the only 2800+ rated player and the only player rated 2700+ was Karpov. Magnus Carlsen's biggest lead was 74 points in October 2013.
Jeff Sonas of Chessmetrics calculates that in April 1876 Wilhelm Steinitz was the top-ranked player in the world, with a rating a record 199 points above that of Henry Bird, the second-ranked player.
Longest duration as number one
Kasparov was the world's highest-rated player for 255 months, a number that is well ahead of all world number ones before or since.
The youngest player to be awarded the grandmaster title by FIDE is Sergey Karjakin. In 2002 he qualified for the title at the age of 12 years, 7 months, and 0 days. See List of youngest grandmasters for the history of this record.
Several players have been awarded honorary or retrospective grandmaster titles based on their past achievements. The oldest of these was Enrico Paoli, who was awarded the title in 1996 at the age of 88.
Apart from retrospective awards, a number of players have achieved the title by winning the World Senior Championship. The oldest player to gain the title in this way was Yuri Shabanov, who won the 2003 event and was awarded the title at the age of 66.
Youngest player to defeat a grandmaster
Simultaneous and blindfold records
Best and worst results in simultaneous exhibitions
In 1922, José Raúl Capablanca, the recently crowned World Champion, played 103 opponents simultaneously in Cleveland. He completed the exhibition in seven hours, scoring 102 wins and one draw (99.5%), the best result ever in a simultaneous exhibition on over 75 boards.
The best result in a simultaneous exhibition solely against grandmasters is former World Champion Garry Kasparov's performance against an Israeli team consisting of Boris Alterman, Alexander Huzman, Ilya Smirin, and Emil Sutovsky at Tel Aviv in 1998. Adding to the difficulty Kasparov played Black in half the games; usually in exhibitions the exhibitor plays White on all boards. A second round was played 2 days later with colors reversed. Kasparov scored 7-1 against an all 2600+ rated team and considers it one of the peak performances of his career.
Paul Morphy also gave an impressive exhibition. On April 26, 1859, at London's St. James Chess Club, Morphy played "five games simultaneously against a group of masters who could be described as among the top ten players of the day", scoring 3–2. He defeated Jules Arnous de Rivière and Henry Bird, drew Samuel Boden and Johann Löwenthal, and lost only to Thomas Wilson Barnes.
The worst result in a simultaneous exhibition given by a master occurred in 1951, when International Master Robert Wade gave a simultaneous exhibition against 30 Russian schoolboys, aged 14 and under. After 7 hours of play, Wade had lost 20 games and drawn the remaining 10 (16.7%).
Most games in blindfold exhibitions
Miguel Najdorf played against 45 opponents in a simultaneous blindfold exhibition given at Sao Paulo in 1947, winning 39, losing 2 and drawing 4 games (after a similar display in Rosario, Argentina, in 1943, against 40 players). Later Janos Flesch (52 games) claimed to have broken this record, but his exhibition was not properly monitored and so it was not recognized. In November 2011, little-known German master Marc Lang broke Najdorf's record, playing 46 opponents. The record was subsequently beaten by Timur Gareyev in December 2016, when he played 48 opponents over 20 hours, scoring 35 wins, 7 draws and 6 losses.
Most players taking part in a multi-simul
On October 21, 2006, a gigantic multi-simul was organized in El Zócalo, Mexico City's central square. About 600 masters played against 20 to 25 opponents each. The total number of players was 13,446 according to the authorities. The tables were arranged in squares of different colors, each containing seven simuls. The square resembled in this way a giant chessboard. Anatoly Karpov was a guest at the event but did not play in the simuls as he was busy signing 1951 copies of his latest book. Guinness World Records acknowledged the event as the largest one held in a single day.
This record was broken on December 24, 2010 in Ahmadabad, India, where about 20,500 played simultaneously. Then-World Champion Viswanathan Anand was a guest of honor for this event and participated in the simul.
Most simultaneous games
On February 8–9, 2011, Iranian grandmaster Ehsan Ghaem-Maghami achieved the Guinness world record for most simultaneous chess games. He played for 25 hours against 604 players, winning 580 (97.35%) of the games, drawing 16, and losing 8.
Longest-running chess column
Leonard Barden's daily chess column for the London Evening Standard began in June 1956, and was published daily in the printed newspaper until July 30, 2010, a total run of 54 years and 1 month. It has since continued online, and is still running as of May 26, 2015.

- Hearst and Knott in their book on blindfold chess give a number of reasons for not crediting Flesch's claimed record, including the large number of very short games, relatively weak opposition, note-taking by Flesch during the exhibition, possible prearrangement of games, the apparent falsity of Flesch's claim that FIDE ratified his claimed record, that Flesch played 12 of the 52 games as Black, the inaccessibility/disappearance of game scores and the documentary film, and opinions from other chess experts questioning Flesch's claim.
