Bishop, knight, and the pair

Which minor piece fits the position?

Neither minor piece is simply better — it depends on the pawns. Open positions with targets on both wings favour the long-range bishop, which can switch sides in a single move. Closed positions with locked pawns favour the knight, which hops over the blockade to reach squares a bishop can't.

Having both bishops — the 'bishop pair' — is a lasting plus, since together they cover squares of both colours. To use the pair, open the position so the bishops can stretch out.

On paper they're equal — the pawn structure decides which is stronger.
Open board: the bishop's range usually wins out.
Closed board: the knight's hops shine.
Facing the two bishops? Trade one off to ease the pressure.

An open position with pawns on both wings: the bishops rake long diagonals and switch flanks in a move. Here the long-range pieces are in their element — a knight would struggle to keep up.
