An official chessboard is an board containing squares
alternating in color between olive green and buff (where "buff" is a color
variously defined as a moderate orange yellow or a light to moderate yellow) on which
the game of chess is played. The checkerboard
is identical to the chessboard, and in both cases, the squares are referred to as
"black" and "white." In chess (as in checkers), the board is
oriented so that each player has a black square on his left.
It is impossible to cover a chessboard from which two opposite corners have been
removed with dominoes.
The above plot shows a chessboard centered at (0, 0) and its inverse about a small circle also centered at (0, 0) (Gardner 1984, pp. 244-245; Dixon
1991).
The illustration above shows an infinite chessboard reflected in a sphere.
