You can help Misplaced Pages by expanding it . Chess tournament A chess tournament is a series of chess games played competitively to determine a winning individual or team. Since the first international chess tournament in London, 1851 , chess tournaments have become
102-413: A crosstable . A crosstable is an arrangement of the results of every game in a tournament in the form of a table. The result of each individual game is recorded in the appropriate cell. Rows contain the player's name and a number indicating their finishing position; individual games can be looked up using these numbers as co-ordinates. Wins are indicated by 1, draws by ½ and losses by 0. For example,
153-407: A draw according to the rules of chess , the player is allowed to stop both clocks and record the draw claim as long as their opponent agrees to the claim. If the opponent disputes the draw claim, the director may be called to come to a conclusion. If the claim is found to be correct, the game is drawn. Once a player has made a move from a position eligible for a draw, they lose their rights to claim
204-412: A draw in that position. The quickplay finish is the phase of the game when all remaining moves must be made in a limited time. If a player has two minutes or less left on their clock, they may ask the arbiter to adjudicate a draw. The arbiter must decide if the player's opponent is making any attempt to win the game by normal means, or if the position can be won in any way. If the arbiter decides against
255-428: A draw, the player's opponent will be awarded two extra minutes of time. Otherwise, the game is drawn, and the decision of the arbiter is final. Players are granted one point (1) for a win, a half point (½) for a draw, and no points (0) for a loss toward their tournament score. A minority of tournaments use alternative scoring systems such as "football scoring" (3 points for a win, 1 point for a draw), but they are treated
306-556: A few tournaments, such as Bilbao and London, have experimented with the football 3-1-0 scoring system to encourage players to go for wins. A tournament that has too many participants for a round-robin format is commonly conducted as a Swiss-system tournament . This is the most common format for amateur events, and is also common at professional level. In the Swiss style, players are paired as far as possible with opponents having same or similar scores. Pairing players for Swiss-system tournaments
357-440: A fixed amount of time for all their moves of the game. The FIDE Handbook designates the following common blitz time controls: Blitz time controls increase the odds that a player would "lose on time", meaning forfeiture of the game due to expiration of their clock time. Blitz tournaments are often documented with the notation "G/5" or "G/15", meaning "game in 5" and "game in 15", respectively. In standard time controls (STCs)
408-400: A handbook giving rules for chess tournaments. This includes sections giving the rules of the game, but there are also sections specifying how tournaments are organized and regulated. A chess clock is a clock with two separate time displays of which only one display can be running at a time. The player with the black pieces will initiate their opponent's timer at the start of the game. Thus
459-531: A large sponsored research program located at MIT. The number VI refers to the PDP-6 machine for which it was written. Greenblatt was inspired to write Mac Hack upon reading MIT Artificial Intelligence Memo 41, or a similar document describing Kotok-McCarthy , which he saw while visiting Stanford University in 1965. A good chess player, he was inspired to make improvements at MIT in 1965 and 1966. In about 2004, he had an opportunity to tell Alan Kotok that searching
510-468: A particular tournament result could count towards a particular title. The starting category for master-level tournaments was category I, which applied to a tournament whose participants had an average rating from 2251 to 2275. From 2276 to 2300 it was a category II tournament, and so on with a further category every 25 points. Categories are no longer used in these calculations, but informally, strong tournaments are sometimes described by category. Through 2005,
561-642: A person in tournament play was the Mac Hack Six , in 1967. Soon after, tournaments were created just for chess computers. In 1970, the first North American Computer Chess Championship (NACCC) was held in New York City, and in 1974, the first World Computer Chess Championship (WCCC) was held in Stockholm . Kaissa , a chess program of the Soviet Union was named the world's first computer chess champion. In 1995,
SECTION 10
#1732868572603612-448: A player has a set amount of time to complete a specified number of moves. If the specified number of moves is met, the player's time will rejuvenate. The first standard time controls, introduced in 1861, were 24 moves in two hours, with the average game lasting five hours. In the mid-1980s, a new format, 40 moves in two hours, proved popular because few games lasted over 60 moves. There are two main forms that provide compensation for both
663-400: A player is forbidden to have a mobile phone or any other electronic means of communication in the playing venue; failure to comply with this may result in a forfeit. Chess score sheets may be used for recording matters relevant to the game. Players should not distract or annoy their competitor in any way. Once a player has finished their game, they are considered a spectator. Refusal of
714-528: A player to comply with the rules may result in penalty, up to and including forfeiture of the game or even disqualification of the player. If two opponents both refuse to obey the rules, the game may be considered lost by both players. In 1976, smoking was banned in a major tournament for the first time (the National Open, Las Vegas ). The arbiter must see that the Laws of Chess are observed and make decisions in
765-450: A qualifying event for the 1993 Women's World Championship. Sylvia Chidi of Nigeria didn't enter the tournament until after the first two rounds were played, so her first two games are listed as forfeited. Relaying moves formerly required another person to copy the moves of the players on a large demonstration board behind the players, and then transmit them via radio or telegram. Advancements in camera technology allowed zooming clearly at
816-793: A requirement for playing tournaments. In 1966 the program was rated 1243 when it lost in the Massachusetts Amateur Championship. In 1967, the program played in four tournaments, winning three games, losing twelve, and drawing three. In 1967 Mac Hack VI defeated Ben Landy with a USCF rating of 1510 in game 3, tournament 2 of the Massachusetts State Championship. Greenblatt published the program with Donald E. Eastlake III and Stephen D. Crocker in MIT Artificial Intelligence Memo 174 and recorded some games there. Mac Hack played by teletype ,
867-417: A second illegal move in the same game, the arbiter shall declare the game lost by the offending player. If a game begins with the piece colors reversed, the game should be stopped and restarted unless an arbiter rules otherwise. If a player displaces any pieces, they should place them in the correct locations on their own time. In games with long time controls , each player is required to record all moves of
918-468: Is no longer common. Most chess tournaments are organized and directed according to the World Chess Federation (FIDE) handbook, which offers guidelines and regulations for conducting tournaments. Chess tournaments are mainly held in either round-robin style , Swiss-system style or elimination style to determine a winning party. Although modern chess had been established since around 1475,
969-403: Is often not an issue, as the tied players often split prizes equally, in case of necessity (for trophies, qualifications to other tournaments, etc.), there are a few ways to achieve tiebreak. In no particular order: Tournament organizers specify the tie-breaking rules (if any) on the entry form. Single-elimination style or knock-out style are also sometimes used for chess tournaments. In fact,
1020-402: Is often quite complicated due to some nontrivial constraints: Swiss tournament pairings were traditionally done by hand using cards. Today, tournament organizers usually use software. Due to the high percentage of draws and the small granularity of the scoring system which is entirely based on final results, it is common for players to have the same score as the tournament finishes. Although it
1071-579: Is reduced when every player plays everyone else. Rating categories are sometimes used to separate players of different levels into different round-robin groups. The World Chess Federation , the Australian Chess Federation and the United States Chess Federation all use different categorization scales to distinguish player ability. Most round robin tournaments use the traditional 1-½-0 scoring system. In recent years, however,
SECTION 20
#17328685726031122-634: Is simply based on the presence or absence of the world's ten highest-ranked players at the time, and does not involve rating numbers. According to this system, the Vienna 1882 chess tournament would compare in strength to Linares 1993 . A time control is a mechanism in tournament play that allows each round of the match to finish in a timely fashion so that the tournament can proceed. The three main types of time controls used in chess tournaments are blitz , standard , and compensation . In blitz chess (also known as sudden death chess) each player starts with
1173-499: The PDP-6 computer DEC donated to MIT (the first working PDP-6, serial number 2). Many versions may exist. During this period the program was compiled about two hundred times. By the time it was published in 1969 Mac Hack had played in eighteen tournaments and hundreds of complete games. The PDP-6 became an honorary member of the Massachusetts State Chess Association and the United States Chess Federation ,
1224-513: The 7 best moves at each of the first two plies, and limiting the search depth to two would have done better than the default widths of "4 3 2 2 1 1 1 1", attempting eight plies in Kotok-McCarthy's REPLYS subroutine which generated each player's next plausible moves. Greenblatt added fifty heuristics that reflected his knowledge of chess. Mac Hack was written in MIDAS macro assembly language on
1275-409: The Laws of Chess. Most chess tournaments are held in either round-robin style, Swiss-system style or single-elimination style. In round-robin tournaments , each participant plays every other participant an equal number of times. Round-robin tournaments involving four participants are known as "quads" or "foursome". Round-robin tournaments are often used for small groups because the element of luck
1326-637: The Olympics, but also in Paris. The Fédération Internationale des Échecs (FIDE) was formed on the closing day of the first unofficial Chess Olympiad. FIDE organized the first official Chess Olympiad in 1927 in which there were 16 participating countries. By the 29th Chess Olympiad in 1990, there were 127 member countries. The Chess Olympiads were held at irregular intervals by FIDE until 1950; since then, they have been held regularly every two years. The first chess engine (a chess playing computer program ) to beat
1377-405: The arbiter at all times. A player must make their own move before offering a draw , and must not stop their own clock and start their opponent's clock before they have made the offer. If a player does not make a move before offering a draw, the opponent can request a move before considering the draw offer (which cannot be retracted). No conditions may be attached to a draw offer. If a player claims
1428-472: The best interest of the competition, but must not interfere with the game otherwise. If a rule is broken, the arbiter may choose from a number of penalties including the following: The arbiter may also expel offending spectators from the venue. Spectators are also forbidden to use mobile phones at any time in the playing area, and may be expelled for it. Member federations are allowed to ask FIDE authorities to give an official decision about problems relating to
1479-498: The competition. Double-elimination tournaments work in the same way as single-elimination tournaments except that a player loses eligibility to take first prize after two losses. Since chess is believed to have a first move advantage for white , to ensure fairness, the players have to face each other in an equal number of white and black games. For example, in the Chess World Cup , players face off each other in two games, except
1530-507: The end of World War II there were 24 international chess tournaments per year, and by 1990 there were well over a thousand. An attempt was made in 1924 to include chess in the Olympic Games . However, because it was very difficult to distinguish between amateur and professional chess players , the event was called off. While the 1924 Summer Olympics was taking place in Paris, the 1st unofficial Chess Olympiad took place separately from
1581-399: The final with four games. Resolving ties is absolutely crucial in this format, with the modern rule generally following: 1. The players play a number of rapid games (2 or 4) until ties are broken. 2. If the players are tied, they keep playing pairs of blitz games until ties are broken, or until a set number of pairs are played (usually 1 or 2 pairs, although it can be up to 5 pairs). 3. If

1632-608: The first World Computer Speed Chess Championship was held in Paderborn , Germany for blitz chess . For a time, computers competed in human tournaments as well, but computers have become so strong that humans are no longer able to compete with them; players now tend to treat them as analysis tools rather than as opponents. Interest remains in computer chess tournaments, especially the World Computer Chess Championship and Top Chess Engine Championship . FIDE publishes
1683-446: The first international chess tournament was held in single-elimination style. In single-elimination tournaments, the loser of a game is immediately eliminated from winning the first prize. In most single-elimination chess tournaments there is a chance for players to compete for positions other than first. Players are normally given seeds based on their rating in order to prevent the highest ranked players from facing each other early in
1734-651: The first tournament (in the sense of structured competitions) was in Leeds in 1841. There was a knockout tournament in London in 1849 and a tournament in Amsterdam in 1851. The first international chess tournament was held in London in 1851. The London 1851 tournament took place during the Great Exhibition , and would serve as a guide for future international chess tournaments that would follow it. The tournament not only showed
1785-490: The following cross table shows the result of the Hastings 1895 chess tournament : From this table, it can be seen that tournament winner Pillsbury lost to Chigorin, Lasker and Schlechter; drew with Blackburne, Walbrodt and Marco; and won his remaining 15 games. In Swiss-system tournaments, results are usually displayed on a round by round basis. There are variants to the way Swiss tournaments are displayed, such as listing wins by
1836-554: The game in algebraic chess notation . If, however, a player reaches less than five minutes on their clock, and does not have an increment of thirty seconds or more, they are excused from recording the remaining game moves until the game has been completed. At the conclusion of the game, both players must sign each other's score sheets and turn them to the event organizer if instructed to do so. In fast chess games , players are not required to record moves, as it would take away from important thinking time. The score sheets must be visible to
1887-676: The game. Advances in chess engines also allow for casual viewers to evaluate the position in real time; for this reason tournament broadcasts commonly include a 30-minute delay. FIDE has rules for disabled players, with the aim of facilitating competition on an equal footing with able-bodied players. Although the Blind Chess Olympiad is the most significant chess event for the blind and visually impaired , players in either group can participate at most standard tournaments including international ones. In some cases, specially designed chessboards with raised squares and pegs are used to aid
1938-466: The letter "W", losses by the letter "L" and draws by the letter "D". Additional symbols may also be used, such as indicating wins by forfeit with "X", losses by forfeit with "F", half point byes (i.e. byes requested by the player) with "H", full point byes (unpaired due to odd number of players) with "B" etc. The following table shows the result of the 1991 Women's Interzonal Tournament in Subotica , Serbia,
1989-517: The need for time controls but it also clearly demonstrated the drawbacks to the knockout elimination tournament format. It was won by Adolf Anderssen of Germany, who became regarded as the world's best chess player as a result. The number of international chess tournaments increased rapidly afterwards. By the end of the 1850s, chess tournaments had been held in Berlin, Paris, Manchester , New York City, San Francisco, Birmingham , and Vienna . By
2040-572: The open section was rewarded $ 30,000, while the winners of lesser sections were rewarded subsequently smaller amounts. Other chess tournaments, such as the World Chess Championship , also reward the winners with a title, such as "World Chess Champion". Lesser tournaments sometimes replace monetary rewards with book prizes or trophies . Mac Hack Mac Hack is a computer chess program written by Richard D. Greenblatt . Also known as Mac Hac and The Greenblatt Chess Program , it
2091-541: The player will receive a half-point, as if they had drawn the game. A player who wins by forfeit or default will also be granted one point. Players are not allowed to take any action that will bring the game into disrepute. For example, deliberate attempts at cheating by sneaking a captured piece back on to the board can be punished by this rule, rather than the rules dealing with illegal moves. Players can not make any use of any outside information. This includes advice, notes, and analysis of another chess board. During play,

2142-488: The player with the white pieces will have their timer running first, and will make the first move. The player or the arbiter may end the game at any time after the player's opponent has overstepped their time limit. If a timed-out clock remains unnoticed, the game will continue as normal. If the game needs to be interrupted, the arbiter shall stop the clock. Due to most tournaments having increment or delay as well as digital clocks being more precise, digital chess clocks are
2193-558: The players are still tied, a single deciding game (Armageddon) will be used, with Black receiving draw odds (draw count as a win) in exchange for White having time advantage (typically 5 vs 4 minutes). The Scheveningen system, first used in Scheveningen , Netherlands in 1923, involves two teams, each member of one team playing against each member of the other team. Typically each team has between 6 and 12 players, and both individual and team prizes may be awarded. Results are reported using
2244-407: The players' board, although relaying moves was still done manually. In the early 2000s, autosensory boards were introduced, allowing moves to be relayed instantaneously, but are not commonly used due to their cost. In elite tournaments, besides cameras on the players' boards, there are also chess commentators – strong chess players who comment on the game and explain the thought processes and plans of
2295-407: The preferred choice of equipment in tournaments. If it is found that the starting position of the pieces was incorrect, the game must be cancelled and restarted. If it is found that an illegal move has been made, the game must return to the position directly before the irregularity. For the first illegal move by a player, the arbiter shall give two minutes extra time to his opponent. If a player makes
2346-414: The same as regular scoring for the purposes of Elo rating . Full-point byes are received when a player is excluded from a round because of an extra player. Thus, in tournaments with an odd number of players, a different player will receive a full-point each round. A full-point bye is equal in points to a normal win. Half-point byes can be requested by a player who will be unavailable for a round. If accepted,
2397-649: The standard form of chess competition among multiple serious players. Today, the most recognized chess tournaments for individual competition include the Candidates Tournament and the Tata Steel Chess Tournament . The largest team chess tournament is the Chess Olympiad , in which players compete for their country's team in the same fashion as the Olympic Games . Since the 1960s, chess computers have occasionally entered human tournaments, but this
2448-504: The strongest tournaments had been classified category XXI. The Zurich Chess Challenge 2014 , held from 29 January to 4 February 2014, was the first ever category XXIII tournament, with an average Elo rating of 2801. The 2014 Sinquefield Cup , held from 27 August to 7 September, was the second category XXIII tournament, with an average Elo rating of 2802. To gauge tournaments held before 1970, Jeff Sonas devised an unofficial class system, intended to roughly correspond to categories. This
2499-424: The time lost in physically making a move and ensuring that a player can avoid having an ever-decreasing amount of time remaining. The winners of chess tournaments are often rewarded with monetary prizes. Often, the chess tournament draws its prizes from a prize fund , dispensing rewards for all the winners in each section. For example, the 2008 World Open chess tournament had a prize fund of $ 400,000. The winner of
2550-409: The visually handicapped, while a tournament assistant can be used to help players with other physical handicaps. FIDE uses tournament results to determine whether a player has qualified for a title , such as Grandmaster . For a number of years, starting in 1970, FIDE classified tournaments in categories according to the average Elo rating of the participants, as part of the calculation of whether
2601-514: Was developed at the Massachusetts Institute of Technology . Mac Hack VI was the first chess program to play in human tournament conditions, the first to be granted a chess rating , and the first to win against a person in tournament play. A pseudocode for the program is given in Figure 11.16 of. Its name comes from Project MAC ("Multi-Level Access Computer" or "Machine-Aided Cognition" )
