Consider a 5 x 5 version of a chessboard with one player having five queens and the other player having three queens. There are no other pieces. Place the queens on the board so that neither player's queens can capture one of his or her opponent's queens.

*** For the purpose of simplicity, assume the white side has the greater number of queens.
