How to checkmate with king and queen (and king and rook)

You are a queen up against a bare king and the game is won. Then the clock runs, moves pile up and somehow it ends in a draw. This happens to a lot of beginners, and it is entirely avoidable. A forced checkmate with a king and a queen takes only a few moves once you know the idea. This guide covers it, then the slightly trickier king and rook mate.

What checkmate needs

To checkmate, you must attack the enemy king and leave it with no escape. A lone king can usually be driven to the edge of the board, because at the edge it has fewer squares. So every method here is the same plan: shrink the space, push the king to an edge, then deliver the final check.

King and queen: the method

The queen is powerful enough to do most of the work. You only need your own king close by to protect the queen when the final check comes.

  1. Place the queen a knight’s move away from the enemy king. This confines the king to a smaller area without giving it a chance to attack your queen. Moving close like this takes away many squares at once.
  2. Make the box smaller with each move, still keeping the queen a knight’s move away. The enemy king shuffles inside; you shrink the space.
  3. When the enemy king is on the edge, bring your own king up to help. Walk it toward the enemy king, ideally to a square two files or ranks away.
  4. Deliver mate with the queen, with your king guarding the queen so it cannot be captured.

A final position to recognise

Black king on h8, white king on f7, white queen moves to g7. The queen gives check, the white king protects it, and the black king has nowhere to go: g8 and h7 are covered by the queen, and g7 is protected. That is checkmate. There are many mirror versions of this pattern around every edge of the board.

The mistake to avoid: stalemate

Stalemate happens when the player to move is not in check but has no legal move. It is a draw, not a win. With a queen it is dangerously easy to do by accident: you take away every square from the lone king without giving check, and the game ends. Before every queen move, ask: after this, does the enemy king have a legal move? If not, you must be giving check. If you are not, choose a different move.

tip: A quick safety check: before moving, count the squares the enemy king can go to. If the answer is zero and you are not giving check, stop and pick another move.

King and rook: the idea

A rook controls fewer squares than a queen, so the plan is slower and more careful. Here the enemy king is driven back one line at a time, and your king plays a bigger role.

  1. Use the rook to cut off the enemy king along a rank or file. It cannot cross that line.
  2. Walk your king toward the enemy king, so that your kings stand facing each other with one square between them (this is called opposition).
  3. When you have the opposition, check with the rook along the line. The enemy king is forced back one rank or file.
  4. Repeat until the enemy king is on the edge. Keep your rook far enough away that the king cannot attack it.
  5. On the edge, the final check with the rook is mate.

A final position to recognise

Black king on a8, white king on a6, and a white rook delivers check along the eighth rank from h8. The black king cannot go to a7 or b7, because your king guards them, and b8 is covered by the rook. That is checkmate.

Rook safety

The enemy king may try to attack your rook. Whenever it steps next to the rook, move the rook along the same line to a safe distance, or make sure your king defends it. A rook that is left hanging becomes a draw.

Practise it

It really helps to rehearse these on a board. Start a chess game on inkmate against the sleepy bot, trade down pieces until you have a queen against a lone king, and practise the box method. Once you can do it every time, try the rook version. You can also set up the pieces with a friend, using the pass-the-phone mode, and take turns defending.

Where to go next

Knowing these finishes is the difference between winning and nearly winning. To get to such positions, start with good openings: chess openings for beginners. New to chess entirely? Start here. And if you are showing a child the ropes, how to teach chess to kids has patient advice.
