In the 1950s, mathematician Claude Shannon wrote a paper about how one could program a computer to play chess. In it, he made a quick calculation to determine how many different games of chess were possible, and came up with the number 10^120. This is a very, very large number -- the number of atoms in the observable universe, by comparison, is only estimated to be around 10^80.
Chess is played on a square board divided into eight rows of squares called ranks and eight columns called files, with a dark square in each player's lower left corner. This is altogether 64 squares. The colors of the squares are laid out in a checker (chequer) pattern in light and dark squares.
