| − | All pieces except for the pawn capture along their lines of motion - if a piece could move to occupy the location of an opponent's piece, it can capture that piece. The only piece that does not attack along lines of motion is the '''pawn''', which can only capture by moving diagonally forward one square. A piece is said to be undefended if it has no piece "supporting" its position - i.e., preventing an opponent from capturing it by threat of losing his attacking piece. | + | All pieces except for the pawn capture along their lines of motion.
