Rooks and Pawns is a term used in the game of chess. It refers to the two types of pieces that make up the majority of the game. Rooks are the tall, castle-like pieces that move in straight lines across the board, while Pawns are the small, foot soldier-like pieces that move one square at a time. Together, these two pieces form the backbone of the game, as they are the most numerous and versatile pieces on the board.
