A rook is a type of bird belonging to the corvid family, which also includes crows and ravens. It is known for its distinctive black plumage and a strong, sturdy build. Rooks are often found in Europe and parts of Asia, where they inhabit open fields and woodlands. They are social birds, frequently seen in large groups, and are known for their intelligence and problem-solving abilities. In chess, a rook is a powerful piece that moves in straight lines, either horizontally or vertically, across the board. It is often represented as a castle or tower and can capture opponent pieces by landing on their square. The rook plays a crucial role in both offense and defense, especially during the endgame, where it can control large areas of the board and support other pieces like the king.
