Rook

The Rook is a castle-like chess piece in the game of chess. Each player starts the game with two rooks, one on each corner on their own side of the chessboard.

Movement

 * The Rook can move horizontally or vertically in any number of unoccupied squares. It does opposite of what a Bishop does, which only moves diagonally.
 * In the opening, the Rook are blocked by pieces next (which is Knight) and in front of itself (which is the Pawn), so the first move can never be a Rook.

Value

 * The Rook is worth 5 points, and the second most value piece in the game of chess. They worth more than Knights or Bishop, but not as valued as a Queen. However, two Rooks worth slightly more than a Queen (10 vs. 9).
 * Winning a rook by exchanging a Bishop or Knight is winning the exchange.
