Rook endgame
A rook endgame is an ending in which each side has a rook and some pawns and no other pieces, and it is the most common type of endgame, so its main ideas are worth learning early.
Rook endgames arise more often than any other kind of ending, so a small set of principles brings a lot of benefit. Activity matters more than a single pawn: a rook that attacks pawns from behind or from the side can hold a game a pawn down, while a passive rook tied to defense can lose a position that is level on material. Put the rook behind passed pawns, as the Tarrasch rule advises. Bring the king toward the center or toward the pawns, since it is a real fighting piece with so few pieces left. Look for the seventh rank, where a rook attacks pawns along the rank and confines the enemy king to the back rank. Learn the two key positions: the Lucena, which wins for the attacker, and the Philidor, which draws for the defender. Typical mistakes are drifting into passive defense, trading when the other side has the better pawn structure, and carelessly letting the king be cut off. Many of these endings are drawn with accurate play, so keep checking and keep the rook active.
Also worth reading is Queen versus rook. Queen versus rook is an endgame in which one side has a queen and the other a rook, with no other pieces, and the queen wins in general but only after patient, precise technique.
Also worth reading is Rook versus pawn. Rook versus pawn is an ending in which a rook faces a single pawn, usually a win for the rook, although an advanced pawn supported by its king can save the game.
A neighboring idea is Second rank defense. Second rank defense is a rook-ending method in which the defender keeps the rook on its own second rank to stop the enemy king stepping up and to keep checking options open.

An active rook controls open lines, attacks enemy pawns or the king from behind or the side, and cannot easily be attacked, which makes it far stronger than a rook that merely sits and defends.
A passive rook is stuck guarding a pawn or a square, often on its back rank or in front of its own pawn, with little scope to attack, so the opponent's pieces gain time and room.
The Tarrasch rule holds that a rook usually belongs behind a passed pawn, whether the pawn is its own or the enemy's, because from the rear the rook gains squares as the pawn moves up instead of losing them.
The seventh rank is the rank where the opponent's pawns usually start, so a rook placed there attacks those pawns from the side and keeps the enemy king confined to its back rank.
The Lucena position is the key winning setup in rook and pawn against rook: the pawn stands on the seventh rank, its king sits on the promotion square, the enemy king is cut off, and building a bridge with the rook wins.
The Philidor position is the textbook draw for the side with the lone rook: the king blocks the pawn, the rook guards its own third rank, and once the pawn steps onto that rank the rook drops back to check from behind.
