A chess variant is a game related to, derived from, or inspired by chess. Such variants can differ from chess in many different ways.
"International" or "Western" chess itself is one of a family of games which have related origins and could be considered variants of each other. Chess developed from chaturanga, from which other members of this family, such as ouk chatrang, shatranj, Tamerlane chess,
shogi, and xiangqi also evolved.
Many chess variants are designed to be played with the equipment of regular chess. Most variants have a similar public-domain status as their parent game, but some have been made into commercial proprietary games. Just as in traditional chess, chess variants can be played over the board, by correspondence, or by computer. Some internet chess servers facilitate the play of some variants in addition to orthodox chess.
In the context of chess problems, chess variants are called heterodox chess or fairy chess. Fairy chess variants tend to be created for problem composition rather than actual play.
There are thousands of known chess variants (see list of chess variants). The Classified Encyclopedia of Chess Variants catalogues around two thousand, with the preface noting that—since creating a chess variant is relatively trivial—many were considered insufficiently notable for inclusion.
History of chess
The origins of the chess family of games can be traced to the game of chaturanga during the time of the Gupta Empire in India. Over time, as the game spread geographically, modified versions of the rules became popular in different regions. In Sassanid Persia, a slightly modified form became known as shatranj. Modifications made to this game in Europe resulted in the modern game. Courier chess was a popular variant in medieval Europe, which had a significant impact on the "main" variant's development.
Other games in the chess family, such as shogi (Japan), xiangqi (China),
and ouk chatran (Cambodian) are also developments from chaturanga made in other regions.

A chessboard is a 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. The columns of a chessboard are known as , the rows are known as , and the lines of adjoining same-coloured squares (each running from one edge of the board to an adjacent edge) are known as .
Robert James Fischer (March 9, 1943 January 17, 2008) was an American chess grandmaster and the eleventh World Chess Champion. A chess prodigy, he won his first of a record eight US Championships at the age of 14. In 1964, he won with an 11–0 score, the only perfect score in the history of the tournament. Qualifying for the 1972 World Championship, Fischer swept matches with Mark Taimanov and Bent Larsen by 6–0 scores. After another qualifying match against Tigran Petrosian, Fischer won the title match against Boris Spassky of the USSR, in Reykjavík, Iceland.
