Queen and Rook
Part of the Basic Mates section of Coddy's Endgames journey. Lesson 1 of 26.
A queen and a rook mate a bare king on their own, the way two rooks do: one piece is the fence across the rank beside him, the other checks the rank he stands on, and the jobs swap every move. The queen is the better fence - and the worse neighbour, so she checks from far away.
