order to make that square available to another piece. Clearance often exposes
the enemy King to an attack. Sometimes the piece blocking the attack is your
piece; sometimes it is your opponent's piece. The logic is simple: if Square A
is occupied and blocking a checkmating attack, clear Square A! Then, deliver
the checkmate. Often, the square is cleared by the sacrifice of a piece.} *
