Chess

Chess is a board game concerning two players. It is played on a chessboard and a square-checkered board with 64 squares agreed in an eight-by-eight grid.

At the beginning of the game each player controls sixteen pieces: one king, one queen, two rooks, two knights, two bishops, and eight pawns. The object of the game is to checkmate the opponent's king, whereby the king is under instantaneous attack (in "check") and there is no way to remove or defend it from attack on the next move.The game's present form emerged in Europe throughout the second half of the 15th century, an evolution of an older Indian game, Shatranj. Theoreticians have developed widespread chess strategies and tactics since the game's inception.

Computers have been used for many years to generate chess-playing machines, and their abilities and insights have contributed appreciably to modern chess theory.

The Chess Olympiad is a popular competition among teams from different nations. Online chess has opened amateur and professional opposition to a wide and varied group of players.
