Also a bishop, knight, or pawn could not be placed on that diagonal, without capture, unless supported. A similar power is possessed by the other pieces, and may be thus expressed: --if a piece command a certain range of squares, the opposite party cannot place on any square of that range a superior piece, or an unsupported equal or inferior piece, without immediate loss. It will be observed, that this is not the power of moving along a line of squares, but of preventing the antagonist from occupying any square of that line without loss. Supposing the board to be about half-cleared of men, the power of the relative pieces in thus preventing the opponent from occupying any square in a particular line, has been calculated to be Pawn... = 2 Knight... = 54 Bishop... = 7, Rook... = 10 Queen... = 17" But if we now omit all hostile proceedings, and consider simply how many squares a piece may command, without taking any opposing piece, we arrive at different results, principally because the pawn moves straight forward when merely making a move, but diagonally when capturing. The proportionate number of optional squares within the reach of the piece at one move, --supposing the board, as before, to be about half-cleared of combatants, --has been calculated at--Pawn... = 1 Knight... = 5 Bishop... = 7 Rook... = 10 Queen... = 164 Suppose we wish to attack a particular piece with one of our own. If ours happen to be a pawn, we can do s...
