How Does the Rook Move in Chess?
The rook moves any number of squares in a straight line, either horizontally along a rank or vertically along a file, but it can never move diagonally.

Picture the rook's reach as a plus-sign radiating out from its square: it can travel as far as it likes along that rank or file until it's blocked by another piece or reaches the edge of the board. Like every piece except the knight, it can't jump over anything in its path — a pawn or another piece sitting between the rook and its target square stops it there.
Capturing with the rook
The rook captures the same way it moves: it slides along a rank or file and takes the first enemy piece it meets, landing on that piece's square. It cannot capture a piece by jumping over another one, and it cannot capture along a diagonal no matter how tempting the target looks.
Why rooks love open files and ranks
Because a rook's power comes entirely from unobstructed lines, it's at its best on an open file (one with no pawns on it) or the seventh rank, where it can sweep across the board with almost no restriction. Early in the game rooks tend to sit passively behind pawns, which is why 'activating the rooks' — getting them onto open lines — is a recurring theme in the middlegame and endgame.
Rook value and special rules
The rook is worth about five points in the standard point-counting system, making it stronger than a bishop or knight (three points each) but weaker than a queen (nine points). It also has one special power beyond its normal movement: together with the king, it takes part in castling, the only move in chess where two pieces move at once.
Frequently asked questions
Can a rook move diagonally?
No. The rook only moves horizontally or vertically, never diagonally. Diagonal movement belongs to the bishop and queen.
How many squares can a rook move?
Any number, as long as the path is clear — from one square to the far edge of the board along its rank or file.
What is a rook worth in points?
A rook is generally valued at five points, more than a knight or bishop (three points each) but less than a queen (nine points).
Can a rook jump over other pieces?
No. Only the knight can jump over pieces. A rook's movement stops at the first piece in its path, friendly or enemy.
