ObjectID: 171. Description Edit | History. Chess is a two-player, abstract strategy board game that represents medieval warfare on an 8x8 board with alternating light and dark squares. Opposing pieces, traditionally designated White and Black, are initially lined up on either side.
There are 32 pieces on the board at the start of a chess game. Each side begins with 16 pieces as follows:   * 8 Pawns  * 2 Rooks  * 2 Knights  * 2 Bishops  * 1 Queen â¦ * 1 King   There is a difference between 'pieces' and 'men' because pawns are generally not considered to be 'men.'  . 3 people found this useful.
