Worksheet: Rook and King Checkmate
Topic: endgame | Level: 3
Use the rook to cut off lines, bring your king with opposition, and mate only when the enemy king is trapped on the edge.
Why This Matters
- A rook mate works by cutting the king off and then using your king to steal the last safe squares.
- Do not bring the rook too close to the enemy king unless your own king is nearby, because the rook can get chased away.
- Opposition matters: your king often stands one file or rank away so the enemy king cannot step back toward the center.
Practice Tasks
- Why can’t a rook checkmate by itself without its king?
- In the mini-game, which edge is Black being pushed toward?
- Solve each rook-mate practice position and underline the move where the rook acts like a wall.

Step 0: Starting Position
Practice Positions
Find each move on paper, then check the Answer Key at the end.
Practice 1
White to move. Find checkmate in one.
Practice 2
Before checking, improve your king. Find the safe king move that helps the rook.
Practice 3
Now use the rook to cut the king off from one more rank.
Practice 4
Finish the rook-and-king technique from here. Find White’s full line to mate.
Mini-Game
Play this with a partner. White should cut off the king with the rook, then use the king to help. If the rook checks without a plan, talk about which escape square was missed.
Answer Key
- The rook needs its own king to cover the final escape squares. Otherwise the enemy king can keep slipping away.
- Black is being pushed toward the back rank and then toward the corner.
- Kf5 improves the king, Ra7+ builds a wall, and the final sequence ends with Rh8#.
Practice Position Solutions
- Practice 1: Rh1# — The white king on f7 already covers g7 and g8, so the black king can't step sideways. Rh1 checks along the h-file, and since g7/g8 are covered by the white king, there is no escape.
- Practice 2: Kf5 — The rook alone cannot mate. Kf5 brings the king closer so it can take away escape squares later.
- Practice 3: Ra7+ — Ra7+ is a useful rook check because it also builds a wall. The black king is pushed closer to the edge.
- Practice 4: Ra8+ Kh7 Rb8 Kh6 Rh8# — The rook first gives check from the edge, then shifts to the next wall, and finally mates once the white king covers the last escape squares.
