Chess is a two player game played on a square, checkered chessboard. Each player moves their sixteen pieces around the board with the intention of checkmating, or isolating, the opposing player's "king" piece.

Chess in an ancient board game, played with pieces that reflect military divisions. Players move their pieces with the goal of trapping the opposing king in a checkmate. Chess can be played casually, or competitively using a timer to regulate gameplay. Chess is also widely available on the internet, which has spread the game's popularity to new generations of players.

Checkmate the opposing player's king.

Chess is played on a square board of eight rows and eight columns, with the colors of each square alternating between light and dark. Pieces are divided into light and dark sets, with each set consisting of sixteen pieces. These pieces are king (1), queen (1), rook (2), bishop (2), knight (2) and pawn (8). Players move pieces around the board with the goal of checkmating the opponent's king. Play can end with a checkmate, a resignation or a draw

Chess traces its roots back to a 6th century Indian game called "chaturanga," which translates to "four divisions of the military." The game was further developed, then spread throughout the Muslim world, by Persia in the 7th century. The Moors introduced the game to Spain in the 10th century, who facilitated the game's introduction to the rest of Europe. Rules were refined during the Middle Ages and Renaissance, making chess one of the most popular games in Europe. The first modern chess tournament was held in London in 1851, with the winner being crowned the game's first world champion. In 1924, the World Chess Federation (FIDE) was founded to govern all international competitions. In 1993, the Professional Chess Association (PCA) was founded as competition to the FIDE. Each crowned independent world champions until 2006, when the titles were unified.
