A Benchmark for Judging Piece Trades
Piece values aren't an official chess rule, but a traditional benchmark that helps players quickly judge whether trading different pieces is a gain or a loss. It's worth remembering, though, that in actual play these values aren't absolute β a piece's position and how actively it's being used matter just as much.
Frequently Asked Questions
Which is stronger, the bishop or the knight?
They share the same point value, but a knight β which can jump over other pieces β tends to be stronger in cramped positions, while a bishop, with its long-range diagonal reach, tends to be stronger on an open board.
Is trading a queen for a rook and a knight a good deal?
On paper it looks close (9 points versus 8), but in practice how favorable the trade is can swing a lot depending on the pieces' positions and the state of the rest of the board.
