The Tarrasch rule holds that a rook usually belongs behind a passed pawn, whether the pawn is its own or the enemy's, because from the rear the rook gains squares as the pawn moves up instead of losing them. Count the [squares](https://georgelichess.com/glossary/square.md) a rook can use on the pawn's file and the rule explains itself. A rook behind a pawn gains a square each time the pawn moves up, while a rook in front loses one every time, until it is boxed against the edge with nothing to do. With your own [passed pawn](https://georgelichess.com/glossary/passed-pawn.md), a rook at the rear backs up every step without blocking anything, so the pawn can march while the rook stays put. Against an enemy passed pawn, a rook at the rear keeps the pawn under fire all the way up the board, so the opponent must keep guarding it, while your rook's file only gets longer as the pawn advances. The guideline carries the name of Siegbert Tarrasch, who stated it for rook endings, and it holds far more often than not. It still has exceptions. A rook in front of an enemy pawn can be the right [blockade](https://georgelichess.com/glossary/blockade.md) when your king is far away and the pawn would otherwise run, and a rook placed to the side can be better when it also cuts the enemy king off from the pawn. Before each pawn move in a rook ending, check which side of the pawn each rook stands on. The side whose rook is behind usually has the easier game. Also called: rooks belong behind passed pawns. ## Example position White to move. The rook on d1 stands behind the passed d5 pawn and guards it from the rear. Each push opens more of the d-file for it, while Black's rook on b5 can only attack from the side. Position (FEN): `8/6k1/8/1r1P4/8/4K3/8/3R4 w - - 0 1` It sits close to [Passive rook](https://georgelichess.com/glossary/passive-rook.md). A passive rook is stuck guarding a pawn or a square, often on its back rank or in front of its own pawn, with little scope to attack, so the opponent's pieces gain time and room.
