93-463: In chess , there are a number of ways that a game can end in a draw , neither player winning. Draws are codified by various rules of chess including stalemate (when the player to move is not in check but has no legal move), threefold repetition (when the same position occurs three times with the same player to move), and the fifty-move rule (when the last fifty successive moves made by both players contain no capture or pawn move). Under
186-542: A time control , there are other ways a draw can occur. In chess games played at the top level, a draw is the most common outcome of a game: of around 22,000 games published in The Week in Chess played between 1999 and 2002 by players with a FIDE Elo rating of 2500 or above, 55 percent were draws. According to chess analyst Jeff Sonas , although an upward draw rate trend can be observed in general master-level play since
279-613: A "proper" Championship (given the qualification scheme), and it left the decision to the corresponding internal Commission. For 2010, it was organized in conjunction with FIDE from the beginning. However, in neither case was an arbiter's report presented to the next FIDE Congress or General Assembly, as would be expected for a World Championship, and indeed occurred previously with the 2008 Blitz Championship. The 2012 Arbiter's report refers to 7th World Blitz Championship thus seeming to imply that 2009 and 2010 events were indeed Championships; although this report can be faulted for referring to
372-408: 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
465-580: A game can end in a draw . The recorded history of chess goes back at least to the emergence of a similar game, chaturanga , in seventh-century India . After its introduction in Persia , it spread to the Arab world and then to Europe. The rules of chess as they are known today emerged in Europe at the end of the 15th century, with standardization and universal acceptance by the end of the 19th century. Today, chess
558-437: A game of rapid chess are, according to FIDE , more than 10 minutes but less than 60 minutes. Rapid chess can be played with or without time increments for each move. When time increments are used, a player can automatically gain, for instance, ten more seconds on the clock after each move. When time increments are used, the total time per player for a 60-move game must be more than 10 minutes but less than 60 minutes. Rapid chess
651-407: A half point to each player. The rules allow for several types of draws: stalemate , threefold or fivefold repetition of a position, if there has been no capture or a pawn being moved in the last fifty or seventy-five moves, if checkmate is impossible, or if the players agree to a draw . In games played under time control , a draw may result under additional conditions. A stalemate
744-607: A match when it defeated Garry Kasparov . Today's chess engines are significantly stronger than the best human players and have deeply influenced the development of chess theory; however, chess is not a solved game . The rules of chess are published by FIDE (Fédération Internationale des Échecs; "International Chess Federation"), chess's world governing body, in its Handbook . 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
837-451: A point, which is similar to how repetitions are sometimes forbidden in xiangqi , shogi , and Go . (Lasker's original proposal was only for stalemate and bare king; it was supported by Richard Réti and considered not harmful – though unnecessary – by Max Euwe . Capablanca thought that doing this for stalemate would be enough.) Engine tests by Kaufman using Komodo suggest that at over-the-board human World Championship level, this would lower
930-400: A position is considered to be a draw if best play leads to a draw – the difficulty of the defence is not taken into account. Soltis calls these positions "drawable". For instance, under that criterion the rook and bishop versus rook endgame is usually a theoretical draw or book draw, but the side with the bishop often wins in practice. In this position from an actual game, the only move to draw
1023-408: A reasonable chance of winning. For example, a draw could be called after a move or two, but this would likely be thought unsporting. In the 19th century, some tournaments, notably London 1883 , required that drawn games be replayed; however, this was found to cause organizational problems due to the backlog. It is now standard practice to score a decisive game as one point to the winner, and a draw as

Other competitions for individuals include the World Junior Chess Championship , the European Individual Chess Championship , the tournaments for the World Championship qualification cycle , and the various national championships . Invitation-only tournaments regularly attract
1209-511: A series of games between two players, or a team competition in which each player of one team plays one game against a player of the other team. Chess's international governing body is usually known by its French acronym FIDE (pronounced FEE-day) ( French : Fédération internationale des échecs), or International Chess Federation. FIDE's membership consists of the national chess organizations of over 180 countries; there are also several associate members, including various supra-national organizations,

Portable Game Notation (PGN)
1395-479: A small increment, the time odds need to be larger to keep the situation balanced: Norway Chess has used 10 minutes to 7 minutes. Some tournaments utilise a bidding system for individual players of each match to decide how little time they would be willing to play with as black. The player with the lower bid for each match receives the black pieces with draw odds. This system minimises the perceived unfairness of Armageddon time controls that are decided in advance before
1488-610: A special clock that beeped every ten seconds to indicate the time to move. Players had to use their full ten seconds and move on the bell. In 1988, Walter Browne formed the World Blitz Chess Association and its magazine Blitz Chess , which folded in 2003. In some chess tournaments and matches, the final standings of the contestants are decided by a series of games with ever-shortening control times as tie breaks. In this case, two games may be played with each time control, as playing with black or white pieces
1581-528: A tournament with colours randomly allocated. Such an idea is reminiscent of the logical use case of fair cake-cutting . Armageddon chess does not scale well to slower time controls, as even in rapid the necessary time odds would need to be too large; in correspondence events or engine vs. engine events, it is simply unworkable. Larry Kaufman , Kai Laskos , and Stephen Pohl have tested using engines ( Stockfish , Komodo , and Houdini ) an alternative solution, allowing for equal times: Black has draw odds, but
1674-802: A two-second increment is preferred. In the case of time increments, the total time per player for a 60-move game must be 10 minutes or less (hence averaging 10 seconds or less per move). For the FIDE World Blitz Championship, each player has 3 minutes plus 2 additional seconds per move, starting from move 1. Bullet chess games have less than three minutes per player, based on a 40-move game; some chess servers rate one-minute-per-player games separately. Lower time controls are called "hyperbullet" and "ultrabullet" for 30-second-per-player and 15-second-per-player games, respectively. Other common time-control options for bullet games include two minutes with one-second increment, one minute with
1767-445: A two-second increment, or one minute with one-second increment. The term lightning can also be applied to this variant. The use of increment in bullet chess is primarily to avoid issues with latency , as well to discourage playing from a lost position in order to win on time (also known as "dirty flagging"). Online bullet chess avoids practical problems associated with live bullet chess, particularly players accidentally knocking over
1860-476: A wide variety of styles. The Staunton pattern is the most common, and is usually required for competition. Chess pieces are divided into two sets, usually light and dark colored, referred to as white and black , regardless of the actual color or design. The players of the sets are referred to as White and Black , respectively. Each set consists of sixteen pieces: one king , one queen , two rooks , two bishops , two knights , and eight pawns . The game

It is sometimes called international chess or Western chess to distinguish it from related games such as xiangqi (Chinese chess) and shogi (Japanese chess). Chess is an abstract strategy game that involves no hidden information and no elements of chance . It

Until about 1980, the majority of English language chess publications used descriptive notation , in which files are identified by the initial letter of
2139-405: Is a type of chess in which each player is given less time to consider their moves than classical chess time controls allow. Fast chess is subdivided, by decreasing time controls, into rapid chess, blitz chess, and bullet chess. Armageddon chess is a particular variation of fast chess in which different rules apply for each of the two players. As of July 2024, the top-ranked blitz chess player in
2232-407: Is an automatic draw, as is a draw due to impossibility of checkmate. A draw by threefold repetition or the fifty-move rule may be claimed by one of the players with the arbiter (normally using his score sheet ), and claiming it is optional. The draw by fivefold repetition or the seventy-five-move rule is mandatory by the arbiter. A claim of a draw first counts as an offer of a draw, and
2325-415: Is compulsory; a player may not skip a turn, even when having to move is detrimental . Each piece has its own way of moving. In the diagrams, crosses mark the squares to which the piece can move if there are no intervening piece(s) of either color (except the knight, which leaps over any intervening pieces). All pieces except the pawn can capture an enemy piece if it is on a square to which they could move if
2418-423: 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;
2511-518: Is more common in blitz and rapid versions. Play is governed by the FIDE Laws of Chess, except as modified by a specific tournament. However, in case of a dispute during a tournament, either player may stop the clock and call the arbiter to make a final and binding judgment. Chess boxing uses a fast version for the chess component of the sport, granting 9 minutes for each side with no increment. The rules for fast chess differ between FIDE and
2604-399: 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
2697-445: Is not allowed to castle short. Engine tests suggest that this is fair, although it has yet to be tried in practice by human grandmasters. Before the advent of digital clocks, five minutes per side was the standard for blitz or speed chess. Before the introduction of chess clocks, chess club "rapid transit" tournaments had referees who called out every ten seconds. The Washington Divan (2445 15th St. NW) had regular weekly games and used
2790-646: Is not enough to win. Thus Kaufman calls this solution "terrible", going against "the very nature of the game": he writes that "The inferior side should be trying to draw, and to penalize Black for obtaining a good result is crazy. It makes chess like a game of ' chicken '; who will 'blink' first and play an unsound move to avoid the mutually bad result of a draw?" Nickel has likewise criticised this idea as "wholly inadequate", creating "an artificial and empty pressure at best", and creating unfairness and incentivising "game manipulations" in team events or double round-robins. Kaufman speaks more favourably of an idea by Ed Epp, which
2883-428: Is not equally liked among players. The short time controls in fast chess reduce the amount of time available to consider each move, and may result in a frantic game, especially as time runs out. A player whose time runs out automatically loses, unless the opposing player has insufficient material to checkmate , in which case the game is a draw. "Losing on time" is possible at even the longer, traditional time controls, but

2976-411: 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. Castling is permissible if the following conditions are met: Castling is still permitted if
3069-548: Is one of the world's most popular games, with millions of players worldwide. Organized chess arose in the 19th century. Chess competition today is governed internationally by FIDE ( Fédération Internationale des Échecs ; the International Chess Federation). The first universally recognized World Chess Champion , Wilhelm Steinitz , claimed his title in 1886; Ding Liren is the current World Champion. A huge body of chess theory has developed since
3162-430: Is played on a chessboard with 64 squares arranged in an 8×8 grid. The players, referred to generically as "White" and "Black" , each control sixteen pieces : one king , one queen , two rooks , two bishops , two knights , and eight pawns . White moves first, followed by Black; then moves alternate. The object of the game is to checkmate (threaten with inescapable capture) the enemy king. There are also several ways
3255-422: Is played on a square board of eight rows (called ranks ) and eight columns (called files ). Although it does not affect game play, by convention the 64 squares alternate in color and are referred to as light and dark squares. Common colors for wooden chessboards are light and dark brown, while vinyl chessboards are commonly buff and green. To start the game, White's pieces are placed on
3348-491: Is recognized in FIDE-sanctioned events; game scores recorded in a different notation system may not be used as evidence in the event of a dispute. Chess is often played casually in public spaces such as parks and town squares. Contemporary chess is an organized sport with structured international and national leagues, tournaments, and congresses . Thousands of chess tournaments, matches, and festivals are held around
3441-491: Is reduced by comparison, meaning that players will either lose or gain (or rarely both) fewer rating points compared to a solely Quick or Regular game. Any time control over 65 minutes counts under the Regular rating only. All of these time controls include the delay added to the time control, such as a 60-minute game with a 5-second delay, which is still considered to be a 60-minute game, not a 65-minute game. As of March 2013,

Yuri Averbakh gives these combinations for the weaker side to draw: Andy Soltis discusses the vagueness of the terms "draw", "drawish", "drawable", "book draw", "easy draw", and "dead draw". In books and chess theory
3627-526: Is usually calculated as 1 point for each game won and one-half point for each game drawn. 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). The term "match" refers not to an individual game, but to either

As 30-minute to 65-minute-per-player time controls are also under the Regular rating system, these games affect both the Quick and Regular ratings and are known as dual-rated games. However, the K factor (a statistic used for ratings)

Viswanathan Anand won the official FIDE 2003 Rapid Championship at the 6th Cap d'Agde event. After no bids in 2004, FIDE optioned

Unlike Quick chess, 5 minutes can also mean game 3+2 (three minutes with a two-second increment ).

Fischer scored seventeen wins, four draws , and one loss (to Viktor Korchnoi ). Mikhail Tal
4650-528: The World Championship finals and the Candidates' sections between 2010 and 2013, 82.3% ended in a draw. Since that time, draw rate in top-level correspondence play has been rising steadily, reaching 97% in 2019. Engine tests strongly suggest that the result of a perfectly played game is a draw, and that the draw margin is quite large: White cannot force a win without Black making significant mistakes. The high draw rate has often led to fears of "draw death", as

The draw rate of elite grandmasters, rated more than 2750 Elo, is, however, significantly higher, surpassing 70% in 2017 and 2018. In top-level correspondence chess under ICCF , where computer assistance is allowed, the draw rate is much higher than in the over-the-board chess: of 1512 games played in

#17327724939544836-472: The clock. Common times are six minutes for White and five minutes for Black or five minutes for White and four minutes for Black. This can also be played with a small increment.

Other ideas have also been suggested, such as the "football scoring": 0 for a loss, 1 for a draw, and 3 for a win, which is equivalent to scoring draws as ⅓–⅓ rather than ½–½. This has been criticised, however. Kaufman argues that this solution misses the point: it reduces the incentive to draw, but the reason for the high draw rate is not one of incentives, but rather that White's first-move advantage

The offer of a draw should be recorded by each player in their score sheet using the symbol (=) as per Appendix C.12 of FIDE Laws of Chess . In early tournaments, draws were often replayed until one of the players won; however, this

For example, one variation of

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

5394-423: 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
5487-407: 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

A piece is moved to either an unoccupied square or one occupied by an opponent's piece, which is captured and removed from play. With the sole exception of en passant , all pieces capture by moving to the square that the opponent's piece occupies. Moving

The duration of a game ranges from long (or "classical") games, which can take up to seven hours (even longer if adjournments are permitted), to bullet chess (under 3 minutes per player for the entire game). Intermediate between these are rapid chess games, lasting between one and two hours per game, a popular time control in amateur weekend tournaments. Time

If the claim is verified or the draw offer accepted, the game is over. Otherwise, the offer or claim is nullified and the game continues; the draw offer is no longer in effect. The correct procedure for an offer of a draw is to first make a move, verbally offer

Any perpetual check situation will eventually be claimable as a draw under the threefold repetition rule or the fifty-move rule; more commonly the players will simply agree a draw. By 1965, perpetual check was no longer in the rules. Although these are the laws as laid down by FIDE and, as such, are used at almost all top-level tournaments, at lower levels different rules may operate, particularly with regard to rapid play finish provisions.
