Rook versus pawn ending

A rook is worth far more than a pawn, but the result is not always immediate. A far-advanced pawn supported by its king can force the rook to find accurate checks, sacrifice itself for the pawn, or settle for a draw. The placement of both kings, the distance to the promotion square, where the pawn becomes a queen, rook, bishop, or knight, and the side to move can change the result.

Plan for the rook side

• Bring the king closer. The rook can usually contain the pawn, but the king often completes the capture safely.
• Use checks or a horizontal or vertical barrier to cut the defending king away from its pawn.
• Attack from behind when it is safe, because the rook keeps room to follow the pawn as it advances.
• Do not capture too early if the enemy king can attack the rook or the pawn will promote with check on the next move.

The pawn side tries to use its king as a shield from checks and advances only when the rook cannot get behind. Promoting with check may gain a decisive tempo. Near the edge of the board, reduced space can either help the rook contain the king or create stalemate tricks.

This is not the rook-and-pawn versus rook ending, where both sides still have a rook. That different material produces theoretical positions such as the Lucena position and the Philidor position.
