Rocade Sud D'Alger
Castling is a move in chess. It consists of moving the king two squares toward a rook on the same and then moving the rook to the square that the king passed over. Castling is permitted only if neither the king nor the rook has previously moved; the squares between the king and the rook are vacant; and the king does not leave, cross over, or finish on a square attacked by an enemy piece. Castling is the only move in chess in which two pieces are moved at once. Castling with the is called ''kingside castling'', and castling with the is called ''queenside castling''. In both algebraic and descriptive notations, castling kingside is written as 0-0 and castling queenside as 0-0-0. Castling originates from the ''king's leap'', a two-square king move added to European chess between the 14th and 15th centuries, and took on its present form in the 17th century. Local variations in castling rules were common, however, persisting in Italy until the late 19th century. Castling does ...

Chess
Chess is a board game for two players, called White and Black, each controlling an army of chess pieces in their color, with the objective to checkmate the opponent's king. It is sometimes called international chess or Western chess to distinguish it from related games, such as xiangqi (Chinese chess) and shogi (Japanese chess). The recorded history of chess goes back at least to the emergence of a similar game, chaturanga, in seventh-century India. The rules of chess as we know them 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 is one of the world's most popular games, played by millions of people worldwide. Chess is an abstract strategy game that involves no hidden information and no use of dice or cards. It is played on a chessboard with 64 squares arranged in an eight-by-eight grid. At the start, each player controls sixteen pieces: one king, one queen, two rooks, t ...

ICCF Numeric Notation
ICCF numeric notation is the official chess notation system of the International Correspondence Chess Federation. The system was devised for use in international correspondence chess to avoid the potential confusion of using algebraic notation, as the chess pieces have different abbreviations depending on language. In ICCF numeric notation, each square of the chessboard has a two-digit designation. The first digit is the number of the ; files are numbered 1 to 8 from left to right from White's point of view. The second digit is the ; ranks are numbered 1 to 8 from nearest to farthest from White's point of view. Each move is denoted by either four or five digits: the first two digits denote the square the moving piece leaves; the following two digits denote the square at which the moving piece arrives; and, where applicable, the fifth digit denotes the piece of promotion. Details In numeric notation, each square is designated with a two-digit number via a coordinate system. Th ...

Portable Game Notation
Portable Game Notation (PGN) is a standard plain text format for recording chess games (both the moves and related data), which can be read by humans and is also supported by most chess software. History PGN was devised around 1993, by Steven J. Edwards, and was first popularized and specified via the Usenet newsgroup rec.games.chess. Usage PGN is structured "for easy reading and writing by human users and for easy parsing and generation by computer programs." The chess moves themselves are given in algebraic chess notation using English initials for the pieces. The filename extension is .pgn. There are two formats in the PGN specification, the "import" format and the "export" format. The import format describes data that may have been prepared by hand, and is intentionally lax; a program that can read PGN data should be able to handle the somewhat lax import format. The export format is rather strict and describes data prepared under program control, similar to a pretty printe ...

Draw By Agreement
A game of chess can end in a draw by agreement. A player may offer a draw at any stage of a game; if the opponent accepts, the game is a draw. In some competitions, draws by agreement are restricted; for example draw offers may be subject to the discretion of the arbiter, or may be forbidden before move 30, or even forbidden altogether. The majority of draws in chess are by agreement. Under FIDE rules, a draw should be offered after making the move and before pressing the game clock, then marked in the scoresheet as ''(=)''. However, draw offers made at any time are valid. If a player offers a draw before making a move, the opponent has the option of requesting a move before deciding whether or not to accept the offer. Once made, a draw offer cannot be retracted and is valid until rejected. A player may offer a draw by asking, "Would you like a draw?", or similar; the French word ''remis'' (literally "reset") is internationally understood as a draw offer and may be used if the pl ...

Threefold Repetition
In chess, the threefold repetition rule states that a player may claim a draw if the same position occurs three times during the game. The rule is also known as repetition of position and, in the USCF rules, as triple occurrence of position.Article 14K.2 in Two positions are by definition "the same" if the same types of pieces occupy the same squares, the same player has the move, the remaining castling rights are the same and the possibility to capture ''en passant'' is the same. The repeated positions need not occur in succession. The reasoning behind the rule is that if the position occurs three times, no real progress is being made and the game could hypothetically continue indefinitely. The game is not automatically drawn if a position occurs for the third time – one of the players, on their turn, must claim the draw with the arbiter. The claim must be made either before making the move which will produce the third repetition, or after the opponent has made a move producing ...

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 the standard form of chess competition among serious players. Today, the most recognized chess tournaments for individual competition include the Linares chess tournament (now defunct) 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 is no longer common. Most chess tournaments are organized and ruled 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. ...
