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.
This ending is a theoretical win for the queen, yet it is long and tricky. Without pawns, it takes many moves and a good grasp of the main ideas. The queen's chief weapon is the fork: a check that also attacks the rook, which wins the rook if the defender is careless. For that reason the defending side keeps the rook close to its king, ideally protected by it, and tries to keep the king in the center, because the queen's winning technique works once the king is pushed to the edge. The stronger side usually works to cut the king off along a file or rank, to drive the defender back, and to use zugzwang, since a king and rook that must move can fall apart. Practical play differs from theory because many club players do not know the winning method and the defender can get a draw through the fifty move rule or through repetition. If you hold the rook, never wander with it, and avoid placing it where a single check forks it. If you hold the queen, make waiting moves that keep everything under control and do not hurry. A common mistake is to check the king without a plan, which lets it slide back toward its rook.
Compare it with Queen endgame. A queen endgame is an ending in which each side still has a queen, usually with a few pawns, where checks, perpetual check and passed pawns tend to decide the result.
