Chess is a board game for two players. It is an abstract strategy game which involves no hidden information and no elements of chance. It is played on a square board containing 64 squares arranged in an 8×8 grid. The players, referred to as "White" and "Black", each control sixteen pieces: one king, one queen, two rooks, two bishops, two knights, and eight pawns; each type of piece has a different pattern of movement.
