World Chess Championship

From Wikipedia, the free encyclopedia

The World Chess Championship is played to determine the World Champion in the board game chess. Both men and women are eligible to contest this title.

The official world championship is generally regarded to have begun in 1886, when the two leading players in the world played a match. From 1886 to 1946, the championship was conducted on an informal basis, with a challenger having to defeat the incumbent in a match to become the new world champion. From 1948 to 1993, the championship was administered by FIDE, the international chess organization. In 1993, the reigning champion (Garry Kasparov) broke away from FIDE, meaning there were two rival championships. This situation remained until 2006, when the title was unified at the World Chess Championship 2006.

The current world champion is Viswanathan Anand, who won the World Chess Championship 2007 and successfully defended his title against Vladimir Kramnik in the World Chess Championship 2008.

In addition, there is a separate event for women only, for the title of Women's World Champion, and separate competitions and titles for juniors, seniors and computers. However, these days the strongest competitors in the junior, senior, and women's categories often forego these niche title events in order to pursue top level competition, although they continue to be part of chess tradition. Computers are barred from competing for the open title.

[edit] History of the world chess championship

Further information: Development of the World Chess Championship

[edit] Unofficial champions (pre-1886)

The first match proclaimed by the players as for the world championship was the match that Wilhelm Steinitz won against Johannes Zukertort in 1886. However, a line of players regarded as the strongest (or at least the most famous) in the world extends back hundreds of years beyond them, and these players are sometimes considered the world champions of their time. They include Ruy López de Segura around 1560, Paolo Boi and Leonardo da Cutri around 1575, Alessandro Salvio around 1600, and Gioachino Greco around 1620.

In the 18th and early 19th century, French players dominated, with Legall de Kermeur (1730–1747), Francois-André Philidor (1747–1795), Alexandre Deschapelles (1800–1820) and Louis de la Bourdonnais (1820–1840) all widely regarded as the strongest players of their time. La Bourdonnais played a series of six matches — and 85 games — against the Irishman Alexander McDonnell, with many of the encounters later being annotated by the American Paul Morphy.

The Englishman Howard Staunton's match victory over another Frenchman, Pierre Charles Fournier de Saint-Amant, in 1843 is considered to have established him as the world's strongest player.^[1] In 1851 Staunton organised the first international tournament in London. He finished fourth, with the decisive winner, the German Adolf Anderssen establishing himself as the leading player in the world.^[2]

Anderssen was a brilliant attacking player, with two of his best games known as the Immortal Game and the Evergreen Game respectively. He has been described as the first modern chess master.^[3]

Anderssen was himself decisively defeated in an 1858 match against the American Paul Morphy, after which Morphy was toasted across the chess-playing world as the world chess champion. A fast player (he took only minutes to decide on his moves, compared with some others who "were notorious not for out-thinking their opponents but out-sitting them", as Steinitz once said), and possessing fearsome talent, he played matches against several leading players, crushing them all.^[4] Soon after, he offered pawn and move odds to anyone who played him. Finding no takers, Morphy abruptly retired from chess the following year, but many considered him the world champion until his death in 1884. His sudden withdrawal from chess at his peak and subsequent mental illness led to his being known as "the pride and sorrow of chess".

This left Anderssen again as possibly the world's strongest active player, a reputation he reinforced by winning the strong London tournament of 1862.

Wilhelm Steinitz narrowly defeated Anderssen in an 1866 match, which some commentators consider the first "official" world championship match.^[5] The match was not declared to be a world championship at the time, and it was only after Morphy's death in 1884 that such a match was declared, a testament to Morphy's dominance of the game (even though he had not played publicly for 25 years).^[6] The use of the term "World Chess Champion" in this era is varied, but it appears that Steinitz, at least in later life, dated his reign from this 1866 match.^[7]

In 1883, Johannes Zukertort won a major international tournament in London, ahead of nearly every leading player in the world, including Steinitz.^[8][9] This tournament established Steinitz and Zukertort as the best two players in the world, and led to the inaugural World Championship match between these two, the World Chess Championship 1886.^[10][11][12] This match, won by Steinitz, though not held under the aegis of any official body, is generally recognized as the first official World Chess Championship match, with Steinitz the game's first official World Champion.

Graham Burgess lists Philidor, de la Bourdonnais, Staunton, and Morphy as players who were acclaimed as the greatest players of their time (Burgess 2000:495).

[edit] Official champions before FIDE (1886-1946)

The championship was conducted on a fairly informal basis through the remainder of the nineteenth century and in the first half of the twentieth: if a player thought he was strong enough, he (or his friends) would find financial backing for a match purse and challenge the reigning world champion. If he won, he would become the new champion. There was no formal system of qualification. However, it is generally regarded that the system did on the whole produce champions who were the strongest players of their day. The players who held the title up until World War II were Steinitz, Emanuel Lasker, José Raúl Capablanca, Alexander Alekhine, and Max Euwe, each of them defeating the previous incumbent in a match.

[edit] The reign of Wilhelm Steinitz

Wilhelm Steinitz' reign is notable for: the first recorded suggestion that a world champion could forfeit the title by declining a credible challenge or by prolonged absence from competition; the first recorded instance of a disputed world championship; the first actual contest that was defined in advance as being for the world championship (Bledow's 1846 proposal came to nothing); the first attempt to regulate contests for the world championship; debates about whether the championship should be decided by a match or a tournament; and differences between commentators about when his reign began, which persist right down to the present day.^[13][14]

There is no evidence that Steinitz claimed the title for himself immediately after winning a match against Adolf Anderssen in 1866, although in his International Chess Magazine (September 1887 and April 1888) he claimed to have been the champion since 1866.^[13] It has been suggested that Steinitz could not make such a claim while Paul Morphy was alive.^[15] (Morphy had defeated Anderssen by a far wider margin in 1858, but retired from chess competition soon after he returned to the USA in 1859, and died in 1884.^[16] The earliest known reference to Steinitz as world champion was in the Chess Player's Chronicle (October 1872), after he beat Johannes Zukertort in their first match.^[13] But the New York Times (11 March 1894),^[17] British Chess Magazine (April 1894) and Emanuel Lasker (Lasker's Chess Magazine, May 1908) dated his reign from 1866,^[13] and in the early 1950s Reuben Fine followed their example.^[16] On the other hand many recent commentators divide Steinitz' reign into an "unofficial" one before he beat Zukertort again in 1886 and the first "official" world championship from that time onwards;^{[18][19][20][21]} Steinitz had insisted that the contract for the 1886 match must specify that the match was "for the Championship of the World" (Chess Monthly, January 1886).^[13]

The Irish Times (6 March 1879) argued that Steinitz had forfeited the title by prolonged absence from competitive chess and therefore Zukertort should be regarded as champion. The Chess Player's Chronicle (18 July 1883) made a more complex argument: other commentators had suggested that Zukertort should be regarded as champion because he had won a major tournament (London 1883, 3 points ahead of Steinitz^[22]); the Chronicle thought tournaments were an unreliable way of deciding the championship and Steinitz' victories in matches gave him the better claim; but, if Zukertort were the champion, he should forfeit the title if he declined a challenge, especially from a challenger with Steinitz' credentials, and in that case the title should revert to Steinitz.^[13]

In 1887 the American Chess Congress started work on drawing up regulations for the future conduct of world championship contests. Steinitz supported this endeavor, as he thought he was becoming too old to remain world champion. The proposal evolved through many forms (as Steinitz pointed out, such a project had never been undertaken before), and resulted in the New York 1889 tournament to select a challenger for Steinitz, rather like the more recent Candidates Tournaments. The tournament was duly played, but the outcome was not quite as planned: Mikhail Chigorin and Max Weiss tied for first place; their play-off resulted in four draws; and neither wanted to play a match against Steinitz - Chigorin had just lost to him and Weiss wanted to get back to his work for the Rothschild Bank. The third prize-winner Isidore Gunsberg was prepared to play Steinitz for the title in New York, and Steinitz won their match in 1890-1891.^[14][23][24] This experiment was not repeated and the 1894 match in which Steinitz lost his title was a private arrangement between the players.^[17]

[edit] Lasker (1894-1920)

Lasker was the first champion after Steinitz; although he did not defend his title in 1897-1906 or 1911-1920, he did string together an impressive run of tournament victories and dominated his opponents. His success was largely due to the fact that he was an excellent practical player. In difficult or objectively lost positions he would complicate matters and use his extraordinary tactical abilities to save the game. He held the title from 1894 to 1921, the longest reign (27 years) of any champion. In that period he defended the title successfully in one-sided matches against Steinitz, Frank Marshall, Siegbert Tarrasch and Dawid Janowski, and was only seriously threatened in a tied 1910 match against Carl Schlechter.

Although Emanuel Lasker defended his title more frequently than Steinitz had, his negotiations for title matches from 1911 onwards were extremely controversial. In 1911 he received a challenge for a world title match against José Raúl Capablanca and, in addition to making severe financial demands, proposed some novel conditions: the match should be considered drawn if neither player finished with a 2-game lead; and it should have a maximum of 30 games, but finish if either player won 6 games and had a 2-game lead (previous matches had been won by the first to win a certain number of games, usually 10; in theory such a match might go on for ever). Capablanca objected to the 2-game lead clause; Lasker took offence at the terms in which Capablanca criticized the 2-game lead condition and broke off negotiations.^[25]

Further controversy arose when, in 1912, Lasker's terms for a proposed match with Akiba Rubinstein included a clause that, if Lasker should resign the title after a date had been set for the match, Rubinstein should become world champion (American Chess Bulletin, October 1913).^[26] When he resumed negotiations with Capablanca after World War I, Lasker insisted on a similar clause that if Lasker should resign the title after a date had been set for the match, Capablanca should become world champion.^[25] On 27 June 1920 Lasker abdicated in favor of Capablanca because of public criticisms of the terms for the match, naming Capablanca as his successor (American Chess Bulletin, July-August 1920). Some commentators questioned Lasker's right to name his successor (British Chess Magazine, August 1920; Rochester Democrat and Chronicle); Amos Burn raised the same objection but welcomed Lasker's resignation of the title (The Field, 3 July 1920). Capablanca argued that, if the champion abdicated, the title must go to the challenger as any other arrangement would be unfair to the challenger (British Chess Magazine, October 1922). Lasker also announced that, if he won his match against Capablanca, he would resign the title so that younger masters could compete for it ("Dr Lasker and the Championship" in American Chess Bulletin, September-October 1920).^[26] In the event Capablanca won their 1921 match easily.^[16]

[edit] Capablanca, Alekhine and Euwe (1921-46)

Capablanca was the last and greatest of the "natural" players: he prepared little for his games, but won them brilliantly. He possessed an astonishing insight into positions simply by glancing at them. Renowned for his ability to gradually convert the tiniest advantages into victory as well as his famous endgame skill, Capablanca was one of the most feared players in history, and once went undefeated for eight years (1916 to 1924).

However, in 1927, Capablanca was shockingly upset by a new challenger, Alexander Alekhine. Before the match, almost nobody gave Alekhine a chance against the dominant Cuban, but Alekhine overcame Capablanca's natural skill with his unmatched drive and extensive preparation (especially deep opening analysis, which became a hallmark of all future grandmasters). The aggressive Alekhine was helped by his fearsome tactical skill, which complicated the game. He also managed to stave off a rematch against Capablanca indefinitely, instead easily winning two title matches against Efim Bogoljubov in 1929 and 1934.

In 1935, Alekhine was unexpectedly defeated by the Dutch Max Euwe, an amateur player who worked as a mathematics teacher. Alekhine convincingly won a rematch in 1937. World War II temporarily prevented any further world title matches, and Alekhine remained world champion until his unexpected death in 1946.

[edit] FIDE-controlled title (1948-1993)

[edit] Soviet dominance (1948 - 1972)

Alekhine's death threw the chess world into chaos. The previous informal system could not deal with this unlikely eventuality. Though Euwe had some claim to the title, he allowed FIDE to step in. Though FIDE had existed since 1924, it lacked power because the strongest chess-playing nation, the Soviet Union, refused to participate. However, upon Alekhine's death, the Soviet Union joined FIDE in order to be a part of the process to select the next champion. FIDE organised a match tournament in 1948 between five of the world's strongest players. The Russian Mikhail Botvinnik won the tournament by a large margin (as well as winning all the sub-matches against all his opponents), and thus the championship, and FIDE continued to organise the championship thereafter.

In place of the previous informal system, a new system of qualifying tournaments and matches was arranged. The world's strongest players were seeded into "Interzonal tournaments", where they were joined by players who had qualified from "Zonal tournaments". The leading finishers in these Interzonals would go on the "Candidates" stage, which was initially a tournament, later a series of knock-out matches. The winner of the Candidates Tournament would then play a match against the reigning champion (who did not have to qualify through this process) for the championship. If a champion was defeated, he had a right to join in a three way match three years later with his successor and the next challenger. (This never eventuated, and in 1957 was replaced with a provision which allowed a defeated champion to play a rematch one year after his loss.) This system worked on a three-year cycle. Such was the dominance of Soviet chess, that in the next two decades (1951 to 1969), every World Championship match would be played in Moscow between two Soviet players.

The winner of the 1948 tournament, Mikhail Botvinnik, would end up being a constant presence in championship matches for over ten years. His marked longevity at the top is generally explained by the fact that he was a tireless worker. It is said he perfected the game as a science, not a sport, through his emphasis on technique over tactics. This longevity is even more impressive considering he had hit his peak during World War II, during which international chess was suspended, and he was the first champion who was forced to play all his challengers. Perhaps most remarkably, he was not a professional chess player, but a decorated engineer by trade.

Botvinnik first successfully defended his title twice over his first six years, holding off both David Bronstein in 1951 and Vasily Smyslov in 1954. Both the matches were drawn 12-12 but Botvinnik retained the title by virtue of being defending champion. Smyslov, however, won the title in 1957 by a score of 12.5 – 9.5, only to lose it once more to Botvinnik in 1958 by a score of 12.5 – 10.5. At the time, Smyslov had the dubious pleasure of being the shortest-reigning world champion, but this 'honour' soon switched hands, to the 'Magician from Riga', Mikhail Tal.

Tal's daring, sacrificial style had brought him success in 1960, overcoming Botvinnik by a score of 12.5 – 8.5. But once more, Botvinnik was not content, and won back his title the following year in a rematch, by the score of 13 – 8, after Tal fell ill. Botvinnik has said: "If Tal would learn to program himself properly, he would have been impossible to play." Unfortunately, he did not, and many believe that Tal was never able to live up to his potential. He remains to this day the shortest-reigning champion.

Botvinnik played just one more world championship match, the World Chess Championship 1963 against the Armenian Tigran Petrosian, losing it 12.5 – 9.5. There was no rematch, because FIDE abolished the rematch rule. Botvinnik retired from championship chess (and retired from active play altogether in 1970) and occupied himself with computer chess and the creation of his famous chess school. Petrosian successfully defended his title in 1966 against Boris Spassky, winning by the narrowest of margins (12.5 – 11.5). In 1969, however, he lost 12.5 – 10.5 to the same challenger.

[edit] Fischer (1972 - 1975)

The next championship, held in Reykjavík (Iceland) in 1972, saw the first non-Soviet finalist since before World War II (the first under FIDE), the young American, Bobby Fischer. Having defeated his Candidates opponents Mark Taimanov, Bent Larsen, and Tigran Petrosian (the first two by the previously unheard-of scores of 6–0), Fischer easily qualified to challenge Spassky. The so-called Match of the Century, possibly the most famous in chess history, had a shaky start: having lost the first game, Fischer defaulted the second after he failed to turn up, complaining about playing conditions. There was concern he would default the whole match rather than play, but he duly turned up for the third game and won it brilliantly. Spassky won only one more game in the rest of the match and was eventually well beaten by Fischer by a score of 12.5 – 8.5. Fischer's dominance drew many parallels to the other famed American chess champion, Paul Morphy. This similarity became all too close three years later.

A line of unbroken FIDE champions had thus been established from 1948 to 1972, with each champion gaining his title by beating the previous incumbent. This came to an end in 1975, however, when reigning champion Fischer refused to defend his title against Soviet Anatoly Karpov when Fischer's demands were not met. Fischer resigned his FIDE title in writing, but privately maintained that he was still World Champion. He went into seclusion and did not play chess in public again until 1992, when he offered Spassky a rematch, again for the World Championship. The general chess public did not take this claim to the championship seriously, since both of them were well past their prime, though the match was greatly appreciated and attracted good media coverage.

[edit] Karpov and Kasparov (1975-1993)

Karpov dominated the 1970s and early 1980s with an incredible string of tournament successes. He convincingly demonstrated that he was the strongest player in the world by defending his title twice against ex-Soviet Viktor Korchnoi, first in Baguio City in 1978 and then in Merano in 1981. His "boa constrictor" style frustrated opponents, often causing them to lash out and err. This allowed him to bring the full force of his Botvinnik-learned dry technique (both Karpov and Kasparov were students at Botvinnik's school) against them, grinding his way to victory.

He eventually lost his title to a fiery, aggressive, tactical player who was equally convincing over the board: Garry Kasparov. The two of them fought five incredibly close world championship matches, the World Chess Championship 1984 (controversially terminated without result with Karpov leading +5 -3 =40), World Chess Championship 1985 (in which Kasparov won the title, 13-11), World Chess Championship 1986 (narrowly won by Kasparov, 12.5–11.5), World Chess Championship 1987 (drawn 12–12, Kasparov retaining the title), and World Chess Championship 1990 (again narrowly won by Kasparov, 12.5–11.5).

[edit] Split title (1993 - 2006)

In 1993, Kasparov and challenger Nigel Short complained of corruption and a lack of professionalism within FIDE and split from FIDE to set up the Professional Chess Association (PCA), under whose auspices they held their match. The event was orchestrated largely by Raymond Keene. Keene brought the event to London (FIDE had planned it for Manchester), and England was whipped up into something of a chess fever: Channel 4 broadcast some 81 programmes on the match, the BBC also had coverage, and Short appeared in television beer commercials. Kasparov crushed Short by five points, and interest in chess in the UK soon died down.

Affronted by the PCA split, FIDE stripped Kasparov of his title and held a championship match between Karpov (champion prior to Kasparov and defeated by Short in the Candidates semi-final) and Jan Timman (defeated by Short in the Candidates final) in the Netherlands and Jakarta, Indonesia. Karpov emerged victorious.

FIDE and the PCA each held a championship cycle in 1993-96, with many of the same challengers playing in both, and Karpov and Kasparov retaining their respective titles. In the PCA cycle, Kasparov defeated Viswanathan Anand in the PCA World Chess Championship 1995. Karpov defeated Gata Kamsky in the final of the FIDE World Chess Championship 1996. Negotiations were held for a reunification match between Kasparov and Karpov in 1996-97, but nothing came of them.^[27]

Soon after the 1995 championship, the PCA folded, and Kasparov had no organisation to choose his next challenger. In 1998 he formed the World Chess Council, which organised a candidates match between Alexei Shirov and Vladimir Kramnik. Shirov won the match, but negotiations for a Kasparov-Shirov match broke down, and Shirov was subsequently omitted from negotiations, much to his disgust. Plans for a 1999 or 2000 Kasparov-Anand match also broke down, and Kasparov organised a match with Kramnik in late 2000. In a major upset, Kramnik won the Classical World Chess Championship 2000 match with two wins, thirteen draws, and no losses.

FIDE, meanwhile, scrapped the Interzonal and Candidates system, instead having a large knock-out event in which a large number of players contested short matches against each other over just a few weeks. (See FIDE World Chess Championship 1998). Very fast games were used to resolve ties at the end of each round, a format which some felt did not necessarily recognize the highest quality play: Kasparov refused to participate in these events, as did Kramnik after he won Kasparov's title in 2000. In the first of these events, champion Karpov was seeded straight into the final, but subsequently the champion had to qualify like other players. Karpov defended his title in the first of these championships in 1998, but resigned his title in anger at the new rules in 1999. Alexander Khalifman took the title in 1999, Anand in 2000, Ruslan Ponomariov in 2002 and Rustam Kasimdzhanov won the event in 2004.

By 2002, not only were there two rival champions, but Kasparov's strong results - he had the top Elo rating in the world and had won a string of major tournaments after losing his title in 2000 - ensured even more confusion over who was World Champion. So in May 2002, American grandmaster Yasser Seirawan led the organisation of the so-called "Prague Agreement" to reunite the world championship. Kramnik had organised a candidates tournament (won later in 2002 by Peter Leko) to choose his challenger. So it was decided that Kasparov played the FIDE champion (Ponomariov) for the FIDE title, and the winners of the two titles played for a unified title.

However, the matches proved difficult to finance and organise. The Kramnik-Leko match, now renamed the Classical World Chess Championship, did not take place until late 2004 (it was drawn, so Kramnik retained his title). Meanwhile, FIDE never managed to organise a Kasparov match, either with 2002 FIDE champion Ponomariov, or 2004 FIDE champion Kasimdzhanov. Partly due to his frustration at the situation, Kasparov retired from chess in 2005, still ranked #1 in the world.

Soon after, FIDE dropped the short knockout format for World Championship and announced the FIDE World Chess Championship 2005, a double round robin tournament to be held in San Luis, Argentina between eight of the leading players in the world. However Kramnik insisted that his title be decided in a match, and declined to participate. The tournament was convincingly won by the Bulgarian Veselin Topalov, and negotiations began for a Kramnik-Topalov match to unify the title.

[edit] Reunified title (2006 onwards)

The reunification match between Topalov and Kramnik was held in late 2006. After much controversy, it was won by Kramnik. Kramnik thus became the first unified and undisputed World Chess Champion since Kasparov split from FIDE to form the PCA in 1993.

Kramnik played to defend his title at the World Chess Championship 2007 in Mexico. This was an 8 player double round robin tournament, the same format as was used for the FIDE World Chess Championship 2005. This tournament was won by Viswanathan Anand, thus making him the current World Chess Champion.

Because Anand's World Chess Champion title was won in a tournament rather than a match, a minority of commentators question the validity of his title.^[28] Kramnik has also made ambiguous comments about the value of Anand's title, but does not claim the title himself.^[29]

Subsequent world championship matches returned to the format of a match between the champion and a challenger. The World Chess Championship 2008 was an 11-game match between the current champion Viswanathan Anand and 2006 champion Vladimir Kramnik. Anand defended his title with 6½‒4½. The World Chess Championship 2009 will be between Anand and the winner of a match between 2005 FIDE champion Veselin Topalov and Chess World Cup 2007 winner Gata Kamsky.^[30]

FIDE has announced that after that, there will be a championship cycle every two years, beginning with the World Chess Championship 2011.^[31] The first stage of 2011 qualification, the FIDE Grand Prix 2008-2009, began in April 2008.
