The Rook is a powerful piece that can move an unlimited number of squares along horizontal (ranks) and vertical (files) lines on the chessboard.
Characteristics
- In terms of value, it is worth approximately 5 pawns.
- It is very effective on open files.

The Rook, together with the King, can perform a special move called castling. This move ensures the King's safety and brings the rook closer to the center.
