White: King plus Rook vs Black: King only. Canonical setup: White king on e1, White rook on a1, Black king in free position.
Definition
K plus R vs K checkmate is the second basic mating technique after K plus Q vs K. Harder because rook cannot "cover" two diagonals like queen. Requires tighter coordination between king and rook. Execution timeline: 15-20 moves from mid-board.
Core Ideas and Principles
Principles: (1) rook cuts off opponent king on a rank or file (separating king from other side of board), (2) own king takes opposition, (3) push opponent king to edge then to corner. Common technique: "ladder method" where king and rook coordinate step-by-step to squeeze opponent king.
Key Move Sequence
Example sequence from the diagram, every move verified legal and ending in mate: 1.Rd1 Ke6 2.Kf2 Ke7 3.Kf3 Ke8 4.Rd2 Kf8 5.Re2 Kg8 6.Kg4 Kh8 7.Kg5 Kh7 8.Rf2 Kg8 9.Kg6 Kh8 10.Rf8#. The pattern to drill: the rook cuts off one rank, the white king steps up to take the opposition, the rook cuts again, and so on until the black king runs out of room on the last rank. Keep the rook far from the black king so it can never be attacked, and use a rook waiting move whenever the white king needs the black king to move first.
Common Mistakes
- 01Mistake
Rook does not cut off, so opponent king moves freely on whole board.
CorrectionAlways start with rook cutting off on nearest rank or file. Then bring king in to squeeze.
- 02Mistake
Opponent king moves to wrong corner (not the one coach targeted).
CorrectionChoose closer starting corner. Rook plus king coordinate push to that corner, avoid letting opponent king escape to far corner.
