The world records in chess listed here are achieved in organized tournament, match, or simultaneous exhibition play.

Game length records

Longest game The longest decisive FIDE-rated game is Billy Fellowes vs Peter Lalić, London 2024, which lasted for 272 moves, at the Third Kingston Invitational.

The longest game played in a world championship is the 6th game of the 2021 World Chess Championship between Magnus Carlsen and Ian Nepomniachtchi, which Carlsen won in 136 moves by resignation. The game lasted nearly 8 hours.

Shortest game Shortest decisive game The fewest moves required to deliver checkmate in chess is two, in what is known as the fool's mate (1.g4 e5 2.f3 Qh4 and variants thereof).

In a tournament game at odds of , 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#.Edward Winter, Chess Note 5858 . The same game had previously been played in Leeky–Mason, Dublin 1867.

If one counts forfeited games as a loss in zero moves,It counts as a loss for tournament score, but not for rating calculations where a forfeit is treated as an unplayed game. then there have been many such forfeits, with some 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.Chess Informant, Volume 98, Šahovski Informator, 2007, p. 295.

Under FIDE rules instituted around 2008, a player who is late for the beginning of a round loses the game, as does a player who has a forbidden electronic device (by default any device). 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.New rule. Good or bad? You decide. susanpolgar.blogspot.com. Retrieved on October 25, 2009. 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.Susan Polgar Daily Chess News and Information, Double forfeit (based on Polgar's translation of Chinese-language Sina Sports , published September 21, 2009). Retrieved on 2009-09-29.

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 between masters 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 drawingTim Krabbé, Entry No. 257 . Retrieved on May 4, 2009. or even winning in this line.)

The shortest game ever lost by a grandmaster because of the position on the board was by GM Yair Kraidman, who lost in four moves against IM Hagen Poetsch at the 2013 Vienna Open (1.e4 c5 2.Nf3 g6 3.d4 cxd4 4.Qxd4 Nc6?? apparently thinking that White captured with the Knight instead of the Queen). Future world champion Viswanathan Anand resigned on move 6 against Alonso Zapata in 1988 after 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+.

Shortest draw A game may be drawn by mutual agreement in any number of moves. Traditionally, it has been common for players to agree to 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.In the World Chess Championship 2016 and 2018, the players were not permitted to agree a draw before move 30. In the 2021 World Championship, this was extended to move 40. 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. 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 stalemate

The shortest known stalemate, composed 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 (diagram). 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). 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 August 14, 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.

Fewest moves played in a tournament In the Premier I group at the 2003 Capablanca Memorial tournament, Péter Székely took just 130 moves (an average of 10 moves per game) to draw all 13 of his games.

Game play records Latest first capture In Rogoff–Williams, World Junior Chess Championship, Stockholm 1969, the first capture (94.bxc5) occurred on White's 94th move. Filipowicz–Smederevac, Polanica-Zdrój 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

In the decisive game Yates–Znosko-Borovsky, Tunbridge Wells 1927, the first capture occurred on Black's 40th move.The game appears in "The Game of Chess" by Harry Golombek, Penguin Books, first published 1954, on page 119.

Longest consideration for a move

Before the introduction of chess clocks, it was common for players to take more than an hour to decide on a move. Among the players who had a reputation for playing particularly slowly (taking over 2 hours for a move) are Alexander McDonnell and Elijah Williams, however, it was not normal practice to time a player's moves so claims about the slowness of a player in an untimed game must be considered unverified.

In Vigo, Spain in 1980, the Brazilian International Master Francisco Trois spent 2 hours and 20 minutes over his 7th move, deciding which of two viable moves to make. After blitzing out another 21 moves in serious time trouble, he resigned. His opponent, Luis Santos, asked him after the game, "How can you think for over two hours when there are only two possible moves? I don't understand." Trois replied, "Neither do I."

National records

Most grandmasters Following the breakup of the Soviet Union, Russia holds the record for greatest number of grandmasters. In the November 2018 rating list, 229 of the 1645 grandmasters were from Russia.

Greatest concentration of resident grandmasters In 2005, Reykjavík, Iceland, with eight grandmasters (Jón L. Árnason, Jóhann Hjartarson, Margeir Pétursson, Friðrik Ólafsson, Thröstur Thórhallsson, Helgi Grétarsson, Hannes Stefánsson, 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.

Strongest team The USSR team that participated in the 13th Olympiad (Munich 1958) had been claimed as the strongest team ever. It was composed of four world champions (Mikhail Botvinnik, Vasily Smyslov, Mikhail Tal and Tigran Petrosian), one world championship challenger (David Bronstein) and Paul Keres, four times runner-up in the Candidates Tournament.

Tournament records Perfect tournament scores In top-class chess it is rare for a player to complete a tournament or match with a 100 percent score. Some examples are: Gustav Neumann at Berlin 1865 (34/34) William Pollock at Belfast 1886 (8/8) Emanuel Lasker at New York 1893 (13/13) Henry Atkins at Amsterdam 1899 (15/15) José Raúl Capablanca at New York 1913 (13/13, including one default) Dawid Janowski at Paris 1914 (9/9) Alexander Alekhine at Moscow 1919–20 (11/11) Boris Kostić at Hastings 1921–22 (7/7)
