Chess is a board game played between two players. It is sometimes called Western chess or international chess to distinguish it from related games such as xiangqi and shogi. The current form of the game emerged in Southern Europe during the second half of the 15th century after evolving from chaturanga, a similar but much older game of Indian origin. Today, chess is one of the world's most popular games, played by millions of people worldwide.
A chessboard is a gameboard used to play chess. It consists of 64 squares, 8 rows by 8 columns, on which the chess pieces are placed. It is square in shape and uses two colours of squares, one light and one dark, in a chequered pattern. During play, the board is oriented such that each player's near-right corner square is a light square.
Checkers, also known as draughts, is a group of strategy board games for two players which involve diagonal moves of uniform game pieces and mandatory captures by jumping over opponent pieces. Checkers is developed from alquerque. The term "checkers" derives from the checkered board which the game is played on, whereas "draughts" derives from the verb "to draw" or "to move".
Fischer random chess, also known as Chess960, is a variation of the game of chess invented by the former World Chess Champion Bobby Fischer. Fischer announced this variation on June 19, 1996, in Buenos Aires, Argentina. Fischer random chess employs the same board and pieces as classical chess, but the starting position of the pieces on the players' home ranks is randomized, following certain rules. The random setup makes gaining an advantage through the memorization of openings impracticable; players instead must rely more on their skill and creativity over the board.
Chess libraries are library collections of books and periodicals on the game of chess. In 1913, preeminent chess historian H. J. R. Murray estimated the total number of books, magazines, and newspaper columns pertaining to chess to be about 5,000 at that time. B. H. Wood estimated that number, as of 1949, to be about 20,000. David Hooper and Kenneth Whyld write that, "Since then there has been a steady increase year by year of the number of new chess publications. No one knows how many have been printed..."
Three-dimensional chess is any chess variant that replaces the two-dimensional board with a three-dimensional array of cells between which the pieces can move. In practical play, this is usually achieved by boards representing different layers being laid out next to each other.
Losing chess is one of the most popular chess variants. The objective of each player is to lose all of their pieces or be stalemated, that is, a misère version. In some variations, a player may also win by checkmating or by being checkmated.
Capablanca chess is a chess variant invented in the 1920s by World Chess Champion José Raúl Capablanca. It incorporates two new pieces and is played on a 10×8 board. Capablanca believed that chess would be played out in a few decades. This threat of "draw death" for chess was his main motivation for creating a more complex version of the game.
Grand Chess is a large-board chess variant invented by Dutch games designer Christian Freeling in 1984. It is played on a 10×10 board, with each side having two additional pawns and two new pieces: the marshal and the cardinal.
A fairy chess piece, variant chess piece, unorthodox chess piece, or heterodox chess piece is a chess piece not used in conventional chess but incorporated into certain chess variants and some chess problems. Compared to conventional pieces, fairy pieces vary mostly in the way they move, but they may also follow special rules for capturing, promotions, etc. Because of the distributed and uncoordinated nature of unorthodox chess development, the same piece can have different names, and different pieces the same name in various contexts. Most are symbolised as inverted or rotated icons of the standard pieces in diagrams, and the meanings of these "wildcards" must be defined in each context separately. Pieces invented for use in chess variants rather than problems sometimes instead have special icons designed for them, but with some exceptions, many of these are not used beyond the individual games for which they were invented.
ChessV is a free computer program designed to play many chess variants. ChessV is an open-source, universal chess variant program with a graphical user-interface, sophisticated AI, support for opening books and other features of traditional chess programs. The developer of this program, Gregory Strong, has been adding more variants with each release of ChessV. Over 100 chess variants are supported, including the developer's few own variants and other exotic variants, and can be programmed to play additional variants. ChessV is designed to be able to play any game that is reasonably similar to chess. ChessV is one of only a few such programs that exist. The source code of this program is freely available for download as well as the executable program.
In chess, promotion is the replacement of a pawn with a new queen, rook, bishop, or knight of the same color. It occurs immediately when the pawn moves to its last rank, with the player choosing the piece of promotion. The new piece does not have to be a previously captured piece. Promotion is mandatory; the pawn cannot remain as a pawn.
David Brine Pritchard was a British chess player, chess writer and indoor games consultant. He gained pre-eminence as an indoor games and mind sports consultant, a role that he in effect created. A natural games player, it was to him that inventors or publishers would turn to organise a championship of a new game, write about it or generally promote it.
Chess became a source of inspiration in the arts in literature soon after the spread of the game to the Arab World and Europe in the Middle Ages. The earliest works of art centered on the game are miniatures in medieval manuscripts, as well as poems, which were often created with the purpose of describing the rules. After chess gained popularity in the 15th and 16th centuries, many works of art related to the game were created. One of the best-known, Marco Girolamo Vida's poem Scacchia ludus, written in 1527, made such an impression on the readers that it singlehandedly inspired other authors to create poems about chess.
The following outline is provided as an overview of and topical guide to chess:
Tri-chess is the name of a chess variant for three players invented by George R. Dekle Sr. in 1986. The game is played on a board comprising 150 triangular cells. The standard chess pieces are present, minus the queens, and plus the chancellor and cardinal compound fairy pieces per side.
Three-man chess is a chess variant for three players invented by George R. Dekle Sr. in 1984. The game is played on a hexagonal board comprising 96 quadrilateral cells. Each player controls a standard army of chess pieces.
Triangular chess refers to a group of chess variants played on boards composed of triangular cells.
A chess variant is a game related to, derived from, or inspired by chess. Such variants can differ from chess in many different ways.
