The answer is Chess.
Football, Volleyball, Cricket, and Hockey are all team sports. Chess is a board game for two players.
In Football, two teams of eleven players try to maneuver the ball into the other team’s goal without using their hands or arms. The team that scores more goals by the end of the game wins.
In Volleyball, two teams of six players are separated by a net. Each team tries to score points by grounding a ball on the other team’s court under organized rules. It has been a part of the official program of the Summer Olympic Games since 1964.
In Cricket, two teams of eleven players play on a field at the centre of which is a 22-yard (20-metre) pitch with a wicket at each end, each comprising two bails balanced on three stumps. The game proceeds when a player on the fielding team, called the bowler, “bowls” (propels) the ball from one end of the pitch towards the wicket at the other end. The batting side has one player at each end of the pitch, with the player at the opposite end of the pitch from the bowler aiming to strike the ball with a bat. The batting side scores runs when either the bowler unfairly bowls the ball to either side of the wicket (unfairly throwing the ball is called a “wide”), or alternatively when either the ball reaches the boundary of the field or the batting side completes a run. The fielding side’s aim is to prevent run-scoring and dismiss each player (so they are “out”, and are said to have “lost their wicket”).
In Chess, two players sit opposite each other on opposite sides of a checkered board with 64 squares arranged in an eight-by-eight grid. Each player begins the game with 16 pieces: one king, one queen, two rooks, two knights, two bishops, and eight pawns. The objective of the game is to checkmate the opponent’s king, whereby the king is under immediate attack (in “check”) and there is no way to remove it from attack.
