Another kind of mathematical chess problems is a domination problem (or covering). In these problems it is requested to find a minimum number of pieces of the given kind and place them on a chess board in such a way, that all free squares of the board are attacked by at least one piece. The minimal number of dominating kings is 9, queens - 5, rooks - 8, bishops - 8, knights - 12. To get 8 dominating rooks one can place them on one of main diagonals.
