Each player has two rooks ( [[File:Video Chess Piece - Black Rook.png|15px]] [[File:Video Chess Piece - Black Rook.png|15px]] [[File:Video Chess Piece - White Rook.png|15px]] [[File:Video Chess Piece - White Rook.png|15px]] ), sometimes called castles. At the start of the game, White's rooks are on Al A1 and HlH1, Black's rooks are on A8 and H8. The rook moves horizontally or vertically, across any number of empty squares. Note that the queen combines the moves of the rook and the bishop - this is why the queen is so very powerful and so valuable.
