The defense is named for János Balogh (1892–1980), who was a Hungarian International Master of correspondence chess , and
192-644: A Chess Olympiad . The invitations were, however, late in being sent, with the result that only four countries participated, and the competition was called the Little Olympiad. The winner was Hungary , followed by Yugoslavia , Romania , and Germany . In 1927, FIDE began organizing the First Chess Olympiad during its 4th Congress in London. The official title of the tournament was the "Tournament of Nations", or "World Team Championship", but "Chess Olympiad" became
288-404: A purse of less than $ 10,000 (equivalent to $ 182,000 in 2023); 20% of the purse was to be paid to the title holder, with the remainder being divided, 60 percent to the winner of the match, and 40% to the loser; the highest purse bid must be accepted. Alekhine , Bogoljubov , Maróczy , Réti , Rubinstein , Tartakower and Vidmar promptly signed them. The only match played under those rules
384-403: A "fast track" entry into the 2007-2009 cycle due to his inability to compete in the 2007 World Chess Championship Tournament . Additionally, FIDE decided that if Kramnik did not win the 2007 championship tournament, he would play a championship match in 2008 against the winner. This provision came into effect when Viswanathan Anand won the tournament and became the world champion. In 1999, FIDE
480-524: A 5–0 lead but by the end of the 48th Kasparov had reduced this to 5–3. At this point the match had lasted for 159 days (from September 1984 to February 1985). Then the match was ended without result by Florencio Campomanes, the President of the World Chess Federation, and a new match was announced to start a few months later. The termination was controversial, as both players stated that they preferred
576-408: A dark square. This may be remembered by the phrases "light on the right" and "queen on her own color". In formal competition, the piece colors for every matchup are allocated to players by the organizers. In informal games, colors are decided either by mutual agreement, or randomly, for example by a coin toss, or by one player concealing a white pawn in one hand and a black pawn in the other and having
672-511: A locale with more transparency. Merenzon said that they would register in the United Kingdom within a few months. As a result, a new company, World Chess Limited, was registered shortly after, replacing Agon as the rights holder in the agreement with FIDE. Kirsan Ilyumzhinov was happy with the agreement on the basis that now FIDE itself did not have to expend resources to find organizers for its premier events. The issue of financial guarantees
768-487: A mistake, as the split in the world championship was unpopular among commercial sponsors and most grandmasters. He began efforts to mend relations with FIDE and supported Campomanes's re-election bid as FIDE president. However, many FIDE delegates viewed Campomanes as corrupt, and he agreed to resign in 1995, provided his successor was Kirsan Ilyumzhinov , the president of the Republic of Kalmykia . Several attempts to reunify
864-504: A more popular title. The event was won by Hungary, with 16 teams competing. In 1928, FIDE recognized Bogoljubow as "Champion of FIDE" after he won a match against Max Euwe . Alekhine, the reigning world champion, attended part of the 1928 Congress and agreed to place future matches for the world title under the auspices of FIDE, although any match with Capablanca should be under the same conditions as in Buenos Aires, 1927, i.e., including
960-483: A negative light on chess and on the federation and found that he had violated the FIDE code of ethics. Sergei Shipov , who also publicly commented in favor of Russia, was not sanctioned, because FIDE decided that his statements were less provocative. In August 2023, FIDE implemented a ban on trans women from playing chess in official women's tournaments organised by them, as well as tournaments providing qualification spots to
1056-424: A new World Champion had won the title by defeating the former champion in a match. Alexander Alekhine 's death created an interregnum that made the normal procedure impossible. The situation was confused, with many respected players and commentators offering different solutions. FIDE found it difficult to organize the early discussions on how to resolve the interregnum , because problems with money and travel in
SECTION 10
#17328584239471152-590: A new organization, the Professional Chess Association (PCA). In response, FIDE stripped Kasparov of his title, removed both Kasparov and Short from the official rating list, and announced a title match between Karpov and Jan Timman , whom Short had defeated in the Candidates Tournament. Both Kasparov and Karpov won their respective matches, both claiming the title of world champion. By 1994, Kasparov realized that separating from FIDE had been
1248-473: A proposal put forward by the Soviet Union (authored by Mikhail Botvinnik ). The 1938 AVRO tournament was used as the basis for the 1948 Championship Tournament . The AVRO tournament had brought together the eight players who were, by general acclamation, the best players in the world at the time. Two of the participants at AVRO—Alekhine and former world champion Capablanca—had since died; but FIDE decided that
1344-553: A purported agreement between Paulson and FIDE President Kirsan Ilyumzhinov was leaked, and then published by Chess.com (and others), which allegedly indicated that Paulson was simply a front man with Ilyumzhinov the ultimate benefactor of Agon. In that Chess.com article Malcolm Pein is quoted as having twice been told by Paulson that Ilyuzmhinov owned Agon, and in a New In Chess article Nigel Short asserted he had also been told this personally by Paulson. In response, FIDE's deputy vice president Georgios Makropoulos pointed out that
1440-488: A quintuple round robin. Botvinnik won, thus becoming world champion, ending the interregnum . The proposals which led to the 1948 Championship Tournament also specified the procedure by which challengers for the World Championship would be selected in a three-year cycle: countries affiliated with FIDE would send players to Zonal tournaments (the number varied depending on the number of strong players each country had);
1536-583: A role it assumed in 1948. The current World Champion is Ding Liren of China. The reigning Women's World Champion is Ju Wenjun from China.

Portable Game Notation (PGN)
1824-409: A strong master at over-the-board chess. The opening is rarely seen today because it weakens Black's kingside somewhat and often results in a backward e-pawn and/or a hole on e6 after Black's light-square bishop is exchanged . International Correspondence Chess Master Keith Hayward has recently written a series of articles arguing that the defense, though risky, is playable. Chess Chess
1920-430: A super-tournament (AVRO) of ex-champions and rising stars should be held to select the next challenger. FIDE rejected this proposal and at their second attempt nominated Salo Flohr as the official challenger. Euwe then declared that: if he retained his title against Alekhine he was prepared to meet Flohr in 1940 but he reserved the right to arrange a title match either in 1938 or 1939 with José Raúl Capablanca, who had lost
2016-441: A tie-breaking rule, with Reuben Fine placed second and Capablanca and Flohr in the bottom places; and the outbreak of World War II in 1939 cut short the controversy. Although competitive chess continued in many countries, including some that were under Nazi occupation, there was no international competition and FIDE was inactive during the war. From the time of Emanuel Lasker 's defeat of Wilhelm Steinitz in 1894, until 1946,

All pieces except the pawn can capture an enemy piece if it is on a square to which they could move if
2592-423: Is controlled using a chess clock that has two displays, one for each player's remaining time. Analog chess clocks have been largely replaced by digital clocks, which allow for time controls with increments . Time controls are also enforced in correspondence chess competitions. A typical time control is 50 days for every 10 moves. Historically, many different notation systems have been used to record chess moves;
2688-399: Is not a permissible response to a check. The object of the game is to checkmate the opponent; this occurs when the opponent's king is in check, and there is no legal way to get it out of check. It is never legal for a player to make a move that puts or leaves the player's own king in check. In casual games, it is common to announce "check" when putting the opponent's king in check, but this
2784-411: Is not required by the rules of chess and is usually not done in tournaments. Once per game, each king can make a move known as castling . Castling consists of moving the king two squares toward a rook of the same color on the same rank, and then placing the rook on the square that the king crossed.

Variations such as "football scoring" (3 points for a win, 1 point for a draw) may be used by tournament organizers, but ratings are always calculated on the basis of standard scoring. A player's score may be reported as total score out of games played (e.g. 5½/8), points for versus points against (e.g. 5½–2½), or by number of wins, losses and draws (e.g. +4−1=3).

After winning the world championship, Fischer criticized the existing championship match format (24 games; the champion retained the title if the match was tied) on the grounds that it encouraged whoever got an early lead to play for draws. While this dispute was going on, Anatoly Karpov won the right to challenge in 1975. Fischer refused to accept any match format other than
3936-449: The 1993 title match, but without consulting Short, as its rules required; Short was traveling to Greece at the time. Upon learning of this, Short reached out to Kasparov, who had harbored distrust for FIDE and its president, Florencio Campomanes , since the abrupt end of his 1984 title match against Anatoly Karpov. Kasparov and Short concluded that FIDE had not secured the best financial deal for them and announced their decision to play under

On February 27, 2022, FIDE issued an official statement condemning
4224-558: The Candidates played a title match against the champion. From 1950 until 1962 inclusive, the Candidates Tournament was a multi-round round-robin—how and why it was changed are described below.

The first controversy took place when Fischer alleged that, at the 1962 Candidates Tournament in Curaçao ,
4320-538: The Soviet players Tigran Petrosian , Paul Keres and Efim Geller had pre-arranged draws in their games played amongst themselves, and that Viktor Korchnoi , another Soviet player, had been instructed to lose to them (Fischer had placed 4th , well behind Petrosian, Keres and Geller). Grandmaster Yuri Averbakh , a member of the Soviet delegation at the tournament, confirmed in 2002 that Petrosian, Keres and Geller privately agreed to draw their games. FIDE responded by changing
4416-715: The World Chess Championship cycle, FIDE also organizes the Candidates Tournament , which determines who will challenge the reigning World Champion, and the qualifying tournaments for the Candidates, such as the Chess World Cup , the FIDE Grand Prix , and the FIDE Grand Swiss Tournament 2019 .

For example, in the animated diagram, the black pawn advances two squares from g7 to g5, and the white pawn on f5 can take it en passant on g6 (but only immediately after the black pawn's advance). When a pawn advances to its eighth rank , as part of the move, it is promoted and must be exchanged for the player's choice of queen, rook, bishop, or knight of

Rules published by national governing bodies , or by unaffiliated chess organizations, commercial publishers, etc., may differ in some details. FIDE's rules were most recently revised in 2023. Chess sets come in
5184-423: The first rank in the following order, from left to right: rook, knight, bishop, queen, king, bishop, knight, rook. Pawns are placed on each square of the second rank. Black's position mirrors White's, with equivalent pieces on every file. The board is oriented so that the right-hand corner nearest each player is a light square; as a result the white queen always starts on a light square, while the black queen starts on
5280-407: The first rank moves to e2"). For pawns, no letter initial is used; so e4 means "pawn moves to the square e4". If the piece makes a capture, "x" is usually inserted before the destination square. Thus Bxf3 means "bishop captures on f3". When a pawn makes a capture, the file from which the pawn departed is used to identify the pawn making the capture, for example, exd5 (pawn on the e-file captures
5376-454: The format of Candidates Tournaments from a multi-round round-robin to a series of elimination matches, initially 10–12 games in duration; however, by the 1970s, the Candidates final would be as long as 24 games.

After the 2018 FIDE elections and the appointment of a new FIDE President, the new management took regaining control over the World Championship cycle as one of their top priorities. In January 2019, FIDE Director-General Emil Sutovsky announced that a new contract has been signed that continues a scaled-back relationship with World Chess (formerly known as AGON) through 2021. In virtue of this new agreement, FIDE reasserted control over

Kasparov won the second match and became world champion. In 1992, Nigel Short emerged as the official challenger for Kasparov's world title after winning the Candidates Tournament . FIDE promptly accepted a bid from Manchester, England, to host
5856-473: The one he proposed. Among Fischer's demands was a requirement that the challenger must beat him by at least two games in order to take his title (Fischer proposed a match format in which the first player to win 10 games wins, with draws not counting, but if the result is 9–9 it is considered a tie). The FIDE argued that it was unfair for a challenger to be able to beat the world champion, yet not take his title. Fischer would not back down, and eventually FIDE awarded

These players were: Max Euwe (from The Netherlands); Botvinnik, Paul Keres and Salo Flohr (from the Soviet Union); and Reuben Fine and Samuel Reshevsky (from the United States). FIDE soon accepted a Soviet request to substitute Vasily Smyslov for Flohr, and Fine withdrew in order to continue his degree studies in psychiatry , so five players competed, in
6336-427: The piece chosen is indicated after the move (for example, e1=Q or e1Q ). Castling is indicated by the special notations 0-0 (or O-O ) for kingside castling and 0-0-0 (or O-O-O ) for queenside castling. A move that places the opponent's king in check usually has the notation " + " added. There are no specific notations for discovered check or double check . Checkmate can be indicated by " # ". At

FIDE accepted this and decided to form a commission to modify the London Rules for future matches, though this commission never met; by the time of the 1929 Congress, a world championship match between Alekhine and Bogoljubow was under way, held neither under the auspices of FIDE nor in accordance with the London Rules. While negotiating his 1937 World Championship re-match with Alekhine, Euwe proposed that if he retained
7008-527: The right to challenge World Champion Boris Spassky in 1972. Grandmaster Pal Benko agreed to relinquish his qualifying place at the Interzonal in Fischer's favor, and the other participants waived their right to claim the spot. FIDE president Max Euwe interpreted the rules very flexibly to allow Fischer to play in the 1970 Interzonal at Palma de Mallorca , which he won convincingly. Fischer then crushed Mark Taimanov , Bent Larsen (both 6–0) and Tigran Petrosian in
7104-402: The rook is under attack, or if the rook crosses an attacked square. When a pawn makes a two-step advance from its starting position and there is an opponent's pawn on a square next to the destination square on an adjacent file, then the opponent's pawn can capture it en passant ("in passing"), moving to the square the pawn passed over. This can be done only on the turn immediately following
7200-407: The same color. Usually, the pawn is chosen to be promoted to a queen, but in some cases, another piece is chosen; this is called underpromotion . In the animated diagram , the pawn on c7 can be advanced to the eighth rank and be promoted. There is no restriction on the piece promoted to, so it is possible to have more pieces of the same type than at the start of the game (e.g., two or more queens). If
7296-400: The sole shareholder. On February 20, 2012, an agreement between Agon and FIDE was made, subject to approval by the 2012 FIDE General Assembly. This approval was forthcoming in September 2012. In October 2014, Agon was sold to its current CEO Ilya Merenzon for the sum of one pound. At the September 2016 FIDE General Assembly, it was resolved that Agon should institute a corporate presence in
7392-415: The square were unoccupied. Pieces are generally not permitted to move through squares occupied by pieces of either color, except for the knight and during castling. When a king is under immediate attack, it is said to be in check . A move in response to a check is legal only if it results in a position where the king is no longer in check. There are three ways to counter a check: Castling
7488-452: The standard system today is short-form algebraic notation . In this system, each square is uniquely identified by a set of coordinates, a – h for the files followed by 1 – 8 for the ranks. The usual format is The pieces are identified by their initials. In English, these are K (king), Q (queen), R (rook), B (bishop), and N (knight; N is used to avoid confusion with king). For example, Qg5 means "queen moves to
7584-520: The title to Alekhine in 1927; if Euwe lost his title to Capablanca then FIDE's decision should be followed and Capablanca would have to play Flohr in 1940. Most chess writers and players strongly supported the Dutch super-tournament proposal and opposed the committee processes favored by FIDE. While this confusion went unresolved: Euwe lost his title to Alekhine; the AVRO tournament in 1938 was won by Paul Keres under
7680-623: The title to Karpov by default. Some commentators have questioned whether FIDE president Max Euwe did as much as he could have to prevent Fischer from forfeiting his world title. FIDE had a number of conflicts with the Soviet Chess Federation . These conflicts included: During his period as president of FIDE (1970–1978) Max Euwe strove to increase the number of member countries, and Florencio Campomanes (president 1982–1995) continued this policy, with each member nation receiving one vote. Former world champion Anatoly Karpov later said this
7776-483: The title, FIDE should manage the nomination of future challengers and the conduct of championship matches. FIDE had been trying since 1935 to introduce rules on how to select challengers, and its various proposals favored selection by some sort of committee. While they were debating procedures in 1937 and Alekhine and Euwe were preparing for their re-match later that year, the Dutch Chess Federation proposed that
7872-502: The world championship in the following years failed for various reasons, including financial constraints and Kasparov's opposition to any plan requiring him to play in a qualifying series. In 2000, Vladimir Kramnik defeated Kasparov in a match for the now-renamed Braingames World Chess Championship, as the PCA had dissolved by then. Kramnik, like Kasparov, was unwilling to play in a qualifying series and strongly objected to FIDE's attempt to decide
7968-495: The world championship through annual knockout tournaments and to shorten game time limits. In 2006, a reunification match was held between Kramnik and Veselin Topalov , which Kramnik won amidst a controversy that resulted in one game being awarded to Topalov. However, the split in the world title had lingering effects, as evidenced by FIDE's complex regulations for the 2007-2009 world championship cycle. FIDE decided to grant Topalov
8064-459: The world every year catering to players of all levels. Tournaments with a small number of players may use the round-robin format, in which every player plays one game against every other player. For a large number of players, the Swiss system may be used, in which each player is paired against an opponent who has the same (or as similar as possible) score in each round. In either case, a player's score
8160-842: The world's strongest players. Examples include Spain's Linares event, Monte Carlo's Melody Amber tournament, the Dortmund Sparkassen meeting, Sofia's M-tel Masters , and Wijk aan Zee's Tata Steel tournament. Regular team chess events include the Chess Olympiad and the European Team Chess Championship . The World Chess Solving Championship and World Correspondence Chess Championships include both team and individual events; these are held independently of FIDE. FIDE The International Chess Federation or World Chess Federation , commonly referred to by its French acronym FIDE ( / ˈ f iː d eɪ / FEE -day Fédération Internationale des Échecs ),
8256-495: Was € 12.84 million , an increase from the 2021 budget which was €4 million . Income is primarily from rights to tournaments such as the Olympiad and World Championship, from various fees and commissions, and from corporate sponsorship and donations. Regions of FIDE are as follows: In 1904, L'union Amicale, a French chess association, attempted to establish an international chess federation. In April 1914, an initiative
8352-524: Was Capablanca vs Alekhine in 1927. In 1922, the Russian master Eugene Znosko-Borovsky , while participating in an international tournament in London, announced that a tournament would be held during the 8th Sports Olympic Games in Paris in 1924 and would be hosted by the French Chess Federation . On July 20, 1924, the participants at the Paris tournament founded FIDE as a kind of players' union. In its early years, FIDE had little power, and it
8448-695: Was a mixed blessing, as the inclusion of so many small, poor countries led to a "leadership vacuum at the head of the world of chess......" Yuri Averbakh said the presence of so many weak countries made it easy to manipulate decisions. The events leading to Garry Kasparov 's winning the world championship involved FIDE in two controversies. While arranging the Candidates Tournament semi-final matches to be played in 1983, FIDE accepted bids to host Kasparov versus Victor Korchnoi in Pasadena, California . The Soviet Union refused to accept this, either because it feared Kasparov would defect or because it thought Kasparov
8544-646: Was also a member of the supervisory board of the Russian Chess Federation . Dvorkovich was also one of the chief organizers of the 2018 FIFA World Cup . Dvorkovich was placed in the US Treasury pre-sanctions list in 2018 as a top Russian government employee. In the elections, held in Batumi (Georgia) in October 2018, Dvorkovich won by 103 votes to 78 against Makropoulos, after Nigel Short withdrew his candidacy at
8640-472: Was also important, though as explained below, these have not always materialized. His estimation of 10–12 million euros to FIDE from the coming cycles has not yet come to fruition either. The condition that Agon would be the sole organizer of Championship events was disputed originally by principally the Bulgarian Chess Federation, with respect to the Candidates matches for 2012. In early 2014,
8736-473: Was clear that about half the credible contenders were Soviet citizens. The Soviet Union realized, however, it could not afford to be left out of the discussions regarding the vacant world championship, and in 1947 sent a telegram apologizing for the absence of Soviet representatives and requesting that the USSR be represented in future FIDE Committees. The eventual solution was similar to FIDE's initial proposal and to
8832-522: Was poorly financed. FIDE's congresses in 1925 and 1926 expressed a desire to become involved in managing the world championship. FIDE was largely happy with the "London Rules", but claimed that the requirement for a purse of $ 10,000 was impracticable and called upon Capablanca to come to an agreement with the leading masters to revise the Rules. FIDE's third congress, in Budapest in 1926, also decided to organize
8928-473: Was recognised by the International Olympic Committee (IOC). Two years later, it introduced the IOC's anti-drugs rules to chess, as part of its campaign for chess to become part of the Olympic Games . In 2012 FIDE entered into a commercial agreement, initially planned to last until 2021, with the company Agon Limited. This company was given rights to organize and commercially exploit the World Chess Championship and
9024-440: Was replaced with FIDE and its banner. On March 22, 2022, FIDE decided to issue a six-month ban from competing in rated tournaments against Russian grandmaster Sergey Karjakin . Karjakin had posted controversial statements on Twitter in which he declared his support for the invasion of Ukraine and for President Vladimir Putin 's characterization of the war as a fight against Nazism. FIDE argued that Karjakin's statements had shed
9120-745: Was taken in St. Petersburg , Russia , to form an international chess federation. Another attempt was made in July 1914 during the Mannheim International Chess Tournament. Further efforts temporarily came to an end as a result of the outbreak of World War I . In 1920, another attempt to organize an international federation was made at the Gothenburg Tournament. Players made the first attempt to produce rules for world championship matches—in 1922, world champion José Raúl Capablanca proposed
9216-417: Was the greater threat to reigning champion Anatoly Karpov. Their refusal would have meant that Kasparov forfeited his chance of challenging for the title. FIDE president Florencio Campomanes negotiated with the Soviet Union, and the match was played in London. In the 1984 world championship match between Karpov and Kasparov the winner was to be the first to win six games. In the first 27 games Karpov gained
