A material imbalance arises when the two sides own different kinds of material, such as a rook against two minor pieces or a queen against rook and bishop. A material imbalance arises when the two sides own different kinds of material, such as a rook against two minor pieces or a queen against rook and bishop, so that simple point totals miss the real strengths of each army. Counting points is a fine start, but it stops working the moment the armies differ in kind. A rook against a [bishop](https://georgelichess.com/glossary/bishop.md) and a pawn, two [knights](https://georgelichess.com/glossary/knight.md) against a rook, a queen against three minor pieces: in each case the totals may be close while the positions are anything but equal. What matters is how well each side's pieces suit the position. Bishops and knights like many pawns on the board, where they find targets and [outposts](https://georgelichess.com/glossary/outpost.md), and they cooperate well with each other. A rook needs [open files](https://georgelichess.com/glossary/open-file.md) and a way in, and it gains strength as pawns disappear. Two minor pieces for a rook is often good for the side with the minor pieces in a crowded middlegame, but the rook side becomes dangerous once the position opens and a pair of minor pieces runs out of targets. [King safety](https://georgelichess.com/glossary/king-safety.md) and pawn structure also count: a rook with several pawns can beat the minor pieces. So the rule is to steer the game toward the kind of position that favors your material. If you hold the rook, open files and trade pawns. If you hold the minor pieces, keep the position closed and the pawns on. When an imbalance appears, write down each side's plan in one sentence before you calculate anything. Also called: imbalance. Compare it with [Exchange advantage](https://georgelichess.com/glossary/exchange-advantage.md). Being up the exchange means you hold a rook while the opponent holds a bishop or knight in its place, a material edge of about two points that is often decisive once lines open and the rook finds targets. A neighboring idea is [Rook versus minor piece](https://georgelichess.com/glossary/rook-versus-minor-piece.md). Rook versus minor piece is an ending or imbalance in which one side has a rook and the other a bishop or knight, so the result depends on the pawns and on how active the pieces are. Also worth reading is [Piece exchange](https://georgelichess.com/glossary/piece-exchange.md). A piece exchange is a trade in which each side gives up a piece of roughly equal value, usually by capture and recapture, changing the balance of attackers, defenders, space and structure on the board.
