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.
An article on Thursday about a Google computer programâs victory over a South Korean master of the board game Go described the gameâs composition incorrectly. Go, believed to be the most complex board game ever created, is played on a board made up of 19 lines by 19 lines, not 19 squares by 19 squares.
