A bishop is usually better when: (1) the position is open and diagonal attacks from far away are possible; (2) there are potential targets or operations on both sides of the board; (3) facing a knight, which the bishop can corral on the side of the board, so that the knight can’t move safely (see diagram 203); and (4) time-gaining or time-losing moves must be played, when the same key squares remain guarded by the bishop after it moves. One drawback with a knight is that it can’t move and still keep an eye on the same squares.
