The rook is a major piece in the game of chess, known for its power and versatility. Each player starts the game with two rooks, placed at the corners of the board on the initial setup: a1 and h1 for White, and a8 and h8 for Black.
The Rook: Moves:
- Horizontal and Vertical Movement: The rook can move any number of squares along a row or column, but cannot leap over other pieces.
- Capturing: The rook captures an opponent's piece by moving to the occupied square.
- Castling: The rook plays a crucial role in castling, a special move that involves the king and either rook. Castling allows the king to move two squares towards a rook, then the rook moves to the square the king crossed. This is the only move that lets two pieces move simultaneously. Conditions: Neither the king nor the rook can have moved previously, the squares between them must be unoccupied, and the king must not be in check or pass through any square under attack.
Value: 5
Diagram 1: The Rook can control the same of squares in any position in an open board.
Tactical or Strategic Use
Open Files: Rooks are most powerful on open files where they can control space and put pressure on the opponent's position.
Rook Lifts: Sometimes, rooks are lifted off the back rank for active operations on the board.
Coordination: Rooks work well when controlling the (powerful in) 7th rank, especially in the endgame against isolated or weak pawns.
Endgame- In the endgame, rooks are particularly valuable because of their ability to control long stretches of the board. They can escort pawns to promotion or cut off the opponent's king. It is the most complex type of endgame where no human can master except the computer.
Endgame Strength: In open endgames, bishops can be more potent than knights because of their long-range and ability to participate in both the attack and defense simultaneously.
In the above diagram, the White pair of rook is better than Black rook plus pair of bishop. White can play 1. Rg7+ Kf8 2. Ref7+ Ke8 3. Rxc7 Kf8 4. Rcf7+ Ke8 5. Rxb7 Kf8 6.Rbf7+ Ke8 7. Rxa7 Kf8 8. Rxh7 all the Black pawns at the 7th rank lost.
Weaknesses
Blocked by Pawns: Rooks are less effective if blocked by one's own or opponent's pawns. They thrive with open lines. Especially in the opening.
In the diagram above, All rooks are restricted, can't attack or capture the oppoent's piece and the position is closed.
Historical Significance: The rook has been an integral part of chess for centuries, evolving in design and movement. In historical and artistic representations of chess, rooks were often depicted as castles or towers, reflecting their stronghold nature on the chessboard.
