Rook (chess piece)
The rook is a major chess piece that moves along ranks and files, begins two per player, participates in castling, and is valued for its power on open lines and in endgames.
Overview
The rook is a major piece used in the board game board game of chess. Each side starts with two rooks, usually placed in the corners of the back rank (a1 and h1 for White; a8 and h8 for Black). In algebraic notation a rook is abbreviated as R and in printed diagrams is often shown as a small figurine. It is commonly called a "rook" or sometimes a "castle" in informal contexts.

Movement and basic rules
The rook moves any number of unoccupied squares along a rank (row) or file (column). It captures by occupying the square of an opposing piece. The rook cannot jump over pieces; any intervening piece blocks its path. Because of this straight-line movement, rooks are strongest on open files and open ranks where their range is unobstructed.
Special rules and interactions
- Castling: A rook participates in castling with the king if neither piece has moved, the squares between them are empty, and the king does not move through or into check. Castling moves the rook to the square the king passes over.
- Promotion: A pawn that reaches the far rank may be promoted to a rook (or another piece), producing an additional rook if desired.
- Value: Rooks are typically assigned a relative material value of about five pawns, making them more valuable than bishops or knights but less than a queen.
Strategic role
Rooks play several key strategic roles. They dominate open files and control ranks, support passed pawns, and combine powerfully in the endgame—two rooks often force mate against a lone king with correct technique. Common rook maneuvers include doubling on a file (placing two rooks on the same file), lifting a rook to the third rank to join an attack, and occupying the seventh rank to attack enemy pawns and pieces from behind.
History and names
The name "rook" derives from the Persian word رخ (rokh), reflecting the piece's origins in early Indo-Arabic forms of the game; for further context see the history of chess. Across languages the rook has been likened to a chariot, tower, or ship, which explains variations in its depiction and terminology. Early chess variants had related pieces with different rules, but the modern rook's straight-line movement has been stable for many centuries.
Notation, examples and variants
In game records the rook is written as R. Practical examples of rook play include rook and pawn endgames—where active rooks and passed pawns decide outcomes—and tactical motifs like back-rank mates that exploit a king trapped behind its pawns. Some regional or historical variants change the piece's appearance or name, but its fundamental role as the long-range orthogonal mover remains central to chess strategy.
