The rook in chess (may be referred to as the castle) is a piece that can move horizontally and vertically any amount of spaces on a chess board but can not jump over pieces. The rook usually has no purpose in the beginning of the game since it blocked by so many pieces and usually makes it into the endgame.
The first diagram shows the basic checkmate position with a rook, which can occur on any edge of the board. The black king can be on any square on the edge of the board, the white king is in opposition to it, and the rook can check from any square on the rank or file (assuming that it can not be captured).
