A related concept to spatial control is that of '''outposts''' and '''open files'''. An open file is one in which there are none of your own pawns. It is strong because it means the heavy pieces (rooks and the queen) can control the file from the safety of distance. Placing both Rooks together on a rank or file with no pieces in between is a powerful method of attack because each rook defends the other. | A related concept to spatial control is that of '''outposts''' and '''open files'''.
