Bishop pair

Owning both bishops while the opponent has a bishop and knight, or two knights.

Two bishops cover both colours and reach across the whole board, so in open positions they coordinate into a lasting, often decisive, advantage — usually reckoned at around half a pawn.

The pair thrives when the position opens and pawns are on both wings; it matters less in blocked positions where a knight's ability to leap and reach an outpost comes into its own.

Why it matters

Whether to trade a bishop for a knight is one of the most frequent strategic decisions in chess, and knowing the value of the pair guides it.

The mistake everyone makes

Trading off one of your bishops for a knight with no concrete reason, handing the opponent the pair and a long-term edge.
