Chess originated in northwest India in the 5th century AD as a game called "chaturanga" which later evolved into the modern game of chess. While the rules differed slightly historically, chess had settled into its modern form by the 17th century. An interesting encounter in the 1920s-1930s saw an old Indian version player defeat world champions using that older form of the game. The basic pieces in chess include the king, queen, rook, bishop, knight and pawn with descriptions provided of their standard movements and objectives in play.
