Minor piece is the collective term for a knight or a bishop. Each is conventionally valued at three pawns, placing both below a rook (five pawns) or a queen (nine pawns) on the standard material scale.

Because they control fewer squares and develop more slowly than major pieces, minor pieces are the units most often exchanged in the opening and middlegame. Giving up a minor piece for a rook is called winning the exchange and normally produces a lasting advantage.

Knights and bishops complement each other. A knight performs best in blocked or closed positions where it can hop over fixed pawns. A bishop needs open diagonals and gains strength as pawns are traded away. For this reason, keeping the bishop pair is a frequent strategic aim whenever the position is expected to open.

In the endgame a lone minor piece cannot force mate against a bare king. Two minor pieces working together, however, can outplay a rook or weave mating nets. Deciding whether to trade your final minor piece or keep it on the board is a recurring practical choice at club level.
