The rook moves any number of squares along its rank or file, provided the path is clear, and it takes part in castling alongside the king. The rook is the first piece that beginners learn to trust in the [endgame](https://georgelichess.com/glossary/endgame.md). It moves in straight lines along ranks and files and cannot jump over pieces. Each side starts with two, standing in the corners. Rooks need open lines, so a classic piece of advice is to put them on [open files](https://georgelichess.com/glossary/open-file.md), or on files that are about to open, and to double them. A [rook on the seventh](https://georgelichess.com/glossary/seventh-rank.md) rank, where the enemy pawns start, often attacks several weaknesses at once. Rooks also have a special role in [castling](https://georgelichess.com/glossary/castling.md), where the king moves two squares toward a rook and that rook crosses over to the square the king passed. A rook that has moved loses the right to castle on its side. In notation the rook is R. Its conventional value is about five pawns, a little more than a bishop or a [knight](https://georgelichess.com/glossary/knight.md). In the endgame, rook activity usually matters more than a pawn, and many drawing and winning methods for rook endings, from cutting the king off to [building a bridge](https://georgelichess.com/glossary/lucena-position.md), are worth learning early. Connect your rooks by moving the other pieces off the back rank. Compare it with [Disambiguation](https://georgelichess.com/glossary/disambiguation.md). Disambiguation is the extra letter or number added to a written move when two identical pieces can move to the same square, such as Nbd2 or R1e2, so the move reads only one way. A neighboring idea is [Chess pieces](https://georgelichess.com/glossary/piece.md). Chess pieces are the sixteen units each side starts with: one king, one queen, two rooks, two bishops, two knights and eight pawns; in everyday speech, though, piece usually means everything except the pawns. A neighboring idea is [Queen](https://georgelichess.com/glossary/queen.md). The queen moves any number of squares along a rank, file or diagonal, provided the path is clear, which makes her the most powerful piece on the board.
