The rook moves in straight lines along the board’s rows and columns. It can move as many empty squares as it wants forwards, backwards, left, or right. Because of their long-range straight movement, rooks are especially powerful when they have open pathways with no pawns blocking their route.
For experienced players
Two rooks working together on the same rank or adjacent ranks are an overwhelming attacking force, and they are the primary pieces used to deliver the classic Ladder Mate.
