The rook is a powerful piece in chess that moves in straight lines, horizontally or vertically, as many squares as it wants (unless blocked by another piece). Think of it like a little tank rolling across the board! Each player starts with two rooks, positioned in the corners of the board. Rooks become especially valuable in the endgame, when the board is more open and they have more room to maneuver. They're also key to performing a special move called "castling," which helps protect your king.
