Chess variantA 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.
Correspondence chessCorrespondence chess is chess played by various forms of long-distance correspondence, traditionally through the postal system. Today it is usually played through a correspondence chess server, a public internet chess forum, or email. Less common methods that have been employed include fax, homing pigeon and phone. It is in contrast to (OTB) chess, where the players sit at a chessboard at the same time, or play each other in real time via the internet.
ChessChess 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.
Chess theoryThe game of chess is commonly divided into three phases: the opening, middlegame, and endgame. There is a large body of theory regarding how the game should be played in each of these phases, especially the opening and endgame. Those who write about chess theory, who are often also eminent players, are referred to as "" or "theoreticians". "Opening theory" commonly refers to consensus, broadly represented by current literature on the openings.

KaissaKaissa (Каисса) was a chess program developed in the Soviet Union in the 1960s. It was named so after Caissa, the goddess of chess. Kaissa became the first world computer chess champion in 1974 in Stockholm. By 1967, a computer program by Georgy Adelson-Velsky, Vladimir Arlazarov, Alexander Bitman and Anatoly Uskov on the M-2 computer in Alexander Kronrod’s laboratory at the Institute for Theoretical and Experimental Physics had defeated Kotok-McCarthy running on the IBM 7090 at Stanford University.
Bobby FischerRobert 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.
Chess endgameIn chess and other similar games, the endgame (or end game or ending) is the stage of the game after the middlegame. The endgame begins when few pieces are left on the board. The line between middlegame and endgame is often not clear, and may occur gradually or with the quick exchange of a few pairs of pieces. The endgame, however, tends to have different characteristics from the middlegame, and the players have correspondingly different strategic concerns.
Online chessOnline chess is chess that is played over the Internet, allowing players to play against each other in real time. This is done through the use of Internet chess servers, which often include a system to pair up individual players based on their rating using an Elo or similar chess rating system. Online chess has existed since the 1970s, but has seen a rapid growth in popularity amidst the COVID-19 pandemic and rise of chess livestreaming. Online chess has existed in various forms including PLATO and play-by-email since the dawn of the Internet in the 1970s.
