Chess
Chess is a two-player board game played on a chessboard, a square-checkered board with 64 squares arranged in an eight-by-eight grid. It is one of the world’s most popular games, played by millions of people worldwide at home, in clubs, online, by correspondence, and in tournaments.
Each player begins the game with sixteen pieces: one king, one queen, two rooks, two knights, two bishops, and eight pawns, each of these types of pieces moving differently. Pieces are used to attack and capture the opponent’s pieces. The object of the game is to checkmate the opponent’s king by placing it under threat of capture (“check”) which cannot be avoided. In addition to checkmate, the game can be won by the voluntary resignation of one’s opponent, which may occur when too much material is lost, or if checkmate appears unavoidable. A game may result in a draw in several ways, and neither player wins. The course of the game is divided in three phases. The beginning of the game is called the opening (with the development of pieces). The opening yields to the phase called the middlegame. The last phase is the endgame, generally characterised by the disappearance of queens.
The first official World Chess Champion, Wilhelm Steinitz, claimed his title in 1886; the current World Champion is Viswanathan Anand from India. In addition to the World Championship, there are the Women’s World Championship, the Junior World Championship, the World Senior Championship, the Correspondence Chess World Championship, the World Computer Chess Championship, and Blitz and Rapid World Championships. The Chess Olympiad is a popular competition among teams from different nations. Online chess has opened amateur and professional competition to a wide and varied group of players. Chess is a recognized sport of the International Olympic Committee, and international chess competition is sanctioned by the FIDE (Fédération Internationale des Échecs or World Chess Federation). There are also many chess variants that have different rules, different pieces, and different boards.
Commencing in the second half of the 20th century computers have been programmed to play chess with increasing success to the point where home computers can play chess at a very high level. In the past two decades computer analysis has contributed significantly to chess theory as understood by human players, particularly in the endgame. The computer program Deep Blue was the first machine player to overcome a reigning World Chess Champion when it defeated Garry Kasparov in 1997.

Chess is played on a square board of eight rows (called ranks and denoted with numbers 1 to 8) and eight columns (called files and denoted with letters a to h) of squares. The colors of the sixty-four squares alternate and are referred to as “light squares” and “dark squares”. The chessboard is placed with a light square at the right-hand end of the rank nearest to each player, and the pieces are set out as shown in the diagram, with each queen on its own color.
The pieces are divided, by convention, into white and black sets. The players are referred to as “White” and “Black”, and each begins the game with sixteen pieces of the specified color. These consist of one king, one queen, two rooks, two bishops, two knights, and eight pawns.

| Initial position: first row: rook, knight, bishop, queen, king, bishop, knight, and rook; second row: pawns |
White always moves first. After the initial move, the players alternately move one piece at a time (with the exception of castling, when two pieces are moved). Pieces are 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 opponent’s pieces by moving to the square that the opponent’s piece occupies. A player may not make any move that would put or leave his king under attack. If the player to move has no legal moves, the game is over; it is either a checkmate—if the king is under attack—or a stalemate—if the king is not.
Each chess piece has its own style of moving. In the diagrams, the dots mark the squares where the piece can move if no other pieces (including one’s own piece) are on the squares between the piece’s initial position and its destination.
The king moves one square in any direction. The king has also a special move which is called castling and involves also moving a rook.
The rook can move any number of squares along any rank or file, but may not leap over other pieces. Along with the king, the rook is involved during the king’s castling move.
The bishop can move any number of squares diagonally, but may not leap over other pieces.
The queen combines the power of the rook and bishop and can move any number of squares along rank, file, or diagonal, but it may not leap over other pieces.
The knight moves to any of the closest squares that are not on the same rank, file, or diagonal, thus the move forms an “L”-shape: two squares vertically and one square horizontally, or two squares horizontally and one square vertically. The knight is the only piece that can leap over other pieces.
The pawn may move forward to the unoccupied square immediately in front of it on the same file; or on its first move it may advance two squares along the same file provided both squares are unoccupied; or it may move to a square occupied by an opponent’s piece which is diagonally in front of it on an adjacent file, capturing that piece. The pawn has two special moves: the en passant capture and pawn promotion.

Castling
Once in every game, each king is allowed to make a special move, known as castling. Castling consists of moving the king two squares along the first rank toward a rook (which is on the player’s first rank[note 1]) and then placing the rook on the last square the king has just crossed. Castling is permissible only if all of the following conditions hold:
Neither of the pieces involved in castling may have been previously moved during the game.
There must be no pieces between the king and the rook.
The king may not be in check, nor may the king pass through squares that are under attack by enemy pieces, nor move to a square where it is in check
Check
When a king is under immediate attack by one or two of the opponent’s pieces, it is said to be in check. A response to a check is a legal move if it results in a position where the king is no longer under direct attack (that is, not in check). This can involve capturing the checking piece; interposing a piece between the checking piece and the king (which is possible only if the attacking piece is a queen, rook, or bishop and there is a square between it and the king); or moving the king to a square where it is not under attack. Castling 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 remove it from attack. It is illegal for a player to make a move that would put or leave his own king in check.
Time control
Besides casual games without any time restriction, chess is also played with a time control, mostly by club and professional players. If a player’s time runs out before the game is completed, the game is automatically lost (provided his opponent has enough pieces left to deliver checkmate). The duration of a game ranges from long games played up to seven hours to shorter rapid chess games, usually lasting 30 minutes or one hour per game. Even shorter is blitz chess, with a time control of three to fifteen minutes for each player, and bullet chess (under three minutes). In tournament play, time is controlled using a game clock that has two displays, one for each player’s remaining time.

Strategy and tactics
Chess strategy consists of setting and achieving long-term goals during the game – for example, where to place different pieces – while tactics concentrate on immediate maneuver. These two parts of the chess-playing process cannot be completely separated, because strategic goals are mostly achieved by the means of tactics, while the tactical opportunities are based on the previous strategy of play. A game of chess is normally divided into three phases: opening, typically the first 10 moves, when players move their pieces to useful positions for the coming battle; then middlegame; and last the endgame, when most of the pieces are gone, kings typically take a more active part in the struggle, and pawn promotion is often decisive.
Opening
A chess opening is the group of initial moves of a game (the “opening moves”). Recognized sequences of opening moves are referred to as openings and have been given names such as the Ruy Lopez or Sicilian Defence. They are catalogued in reference works such as the Encyclopaedia of Chess Openings. There are dozens of different openings, varying widely in character from quiet positional play (for example, the Réti Opening) to very aggressive (the Latvian Gambit). In some opening lines, the exact sequence considered best for both sides has been worked out to more than 30 moves. Professional players spend years studying openings and continue doing so throughout their careers, as opening theory continues to evolve.
The fundamental strategic aims of most openings are similar:
Development: This is the technique of placing the pieces (particularly bishops and knights) on useful squares where they will have an optimal impact on the game.
Control of the center: Control of the central squares allows pieces to be moved to any part of the board relatively easily, and can also have a cramping effect on the opponent.
King safety: It is critical to keep the king safe from dangerous possibilities. A correctly timed castling can often enhance this.
Pawn structure: Players strive to avoid the creation of pawn weaknesses such as isolated, doubled, or backward pawns, and pawn islands – and to force such weaknesses in the opponent’s position.
Most players and theoreticians consider that White, by virtue of the first move, begins the game with a small advantage. This initially gives White the initiative.Black usually strives to neutralize White’s advantage and achieve equality, or to develop dynamic counterplay in an unbalanced position
Middlegame
Main article: Chess middlegame
The middlegame is the part of the game which starts after the opening. There is no clear line between the opening and the middlegame, but typically the middlegame will start when most pieces have been developed. (Similarly, there is no clear transition from the middlegame to the endgame; see start of the endgame.) Because the opening theory has ended, players have to form plans based on the features of the position, and at the same time take into account the tactical possibilities of the position. The middlegame is the phase in which most combinations occur. Combinations are a series of tactical moves executed to achieve some gain. Middlegame combinations are often connected with an attack against the opponent’s king; some typical patterns have their own names; for example, the Boden’s Mate or the Lasker–Bauer combination.
Specific plans or strategic themes will often arise from particular groups of openings which result in a specific type of pawn structure. An example is the minority attack, which is the attack of queenside pawns against an opponent who has more pawns on the queenside. The study of openings is therefore connected to the preparation of plans that are typical of the resulting middlegames.
Another important strategic question in the middlegame is whether and how to reduce material and transition into an endgame (i.e. simplify). Minor material advantages can generally be transformed into victory only in an endgame, and therefore the stronger side must choose an appropriate way to achieve an ending. Not every reduction of material is good for this purpose; for example, if one side keeps a light-squared bishop and the opponent has a dark-squared one, the transformation into a bishops and pawns ending is usually advantageous for the weaker side only, because an endgame with bishops on opposite colors is likely to be a draw, even with an advantage of a pawn, or sometimes even with a two-pawn advantage.

The best players can be awarded specific lifetime titles by the world chess organization FIDE:
Grandmaster (shortened as GM; sometimes International Grandmaster or IGM is used) is awarded to world-class chess masters. Apart from World Champion, Grandmaster is the highest title a chess player can attain. Before FIDE will confer the title on a player, the player must have an Elo chess rating (see below) of at least 2500 at one time and three favorable results (called norms) in tournaments involving other Grandmasters, including some from countries other than the applicant’s. There are other milestones a player can achieve to attain the title, such as winning the World Junior Championship.
International Master (shortened as IM). The conditions are similar to GM, but less demanding. The minimum rating for the IM title is 2400.
FIDE Master (shortened as FM). The usual way for a player to qualify for the FIDE Master title is by achieving a FIDE rating of 2300 or more.
Candidate Master (shortened as CM). Similar to FM, but with a FIDE rating of at least 2200.
All the titles are open to men and women. Separate women-only titles, such as Woman Grandmaster (WGM), are available. Beginning with Nona Gaprindashvili in 1978, a number of women have earned the GM title, and most of the top ten women in 2006 hold the unrestricted GM title.[note 5]
As of August 2011, there are 1363 active grandmasters and 3153 international masters in the world. Top three countries with the largest numbers of grandmasters are Russia, Ukraine, and Germany, with 208, 78, and 76. The country with most grandmasters per capita is Iceland, with 11 GMs and 13 IMs among the population of 310,000
International titles are awarded to composers and solvers of chess problems and to correspondence chess players (by the International Correspondence Chess Federation). National chess organizations may also award titles, usually to the advanced players still under the level needed for international titles; an example is the Chess expert title used in the United States.
In order to rank players, FIDE, ICCF, and national chess organizations use the Elo rating system developed by Arpad Elo. Elo is a statistical system based on the assumption that the chess performance of each player in their games is a random variable. Arpad Elo thought of a player’s true skill as the average of that player’s performance random variable, and showed how to estimate the average from results of player’s games. The US Chess Federation implemented Elo’s suggestions in 1960, and the system quickly gained recognition as being both fairer and more accurate than older systems; it was adopted by FIDE in 1970.[note 6] The highest ever FIDE rating was 2851, which Garry Kasparov had on the July 1999 and January 2000 lists.
