Use the queen to restrict, then the king to support
With king and queen against a bare king, a reliable learning plan is to reduce the defender’s space, bring your own king close and build a supported mate at the edge. You do not need to give check every turn. A quiet queen move can remove more useful squares than a long series of checks.
The queen is powerful enough to create stalemate accidentally, so every restriction move needs an escape-square check. Before the defender is actually in checkmate, leave at least one legal move. Think of the task as managing a small box, not simply chasing the king wherever it runs.
The demonstration begins with the defender already restricted. It is a complete legal line from that composed starting position to mate, with cooperative teaching choices. It is not a claim of the shortest forced mate from an arbitrary queen ending.
A teaching line: restrict the seventh rank, bring the king closer, then give supported mate.
Position FEN
k7/8/8/2K5/3Q4/8/8/8 w - - 0 1Reduce the box without losing the queen
A queen controls a rank and file at once. Place her where those lines stop the opposing king from returning toward the centre. Keep her outside the enemy king’s capture range unless she is protected. An unprotected queen next to a king can be taken even if you intended a clever net.
When the defender moves, ask whether you can tighten the boundary safely. If not, improve your king rather than forcing an unnecessary queen move. A queen sitting well can remain still while the king catches up.
In the first decision diagram, White plays Qd7 to cut off the seventh rank. Black retains moves on the eighth rank, so the position continues. The move creates a useful boundary without checking; that is progress.
Qd7 creates a boundary while leaving Black legal moves.
Position FEN
k7/8/8/2K5/3Q4/8/8/8 w - - 0 1Bring your king into the net
Your king covers adjacent escape squares and protects the queen’s close-range mating square. Approach while respecting the rule that kings cannot stand adjacent. The defending king may oppose your king, so count the exact squares rather than judging distance by appearance.
A useful practice question is: which escape square does my king cover that my queen cannot safely cover alone? In the final net, the king on c6 protects b7. That support makes Qb7 a checking move the black king cannot answer by capturing the queen.
If your king is far away, do not rush the queen into a position that leaves the defender motionless. Keep a safe waiting area and use your turns to improve the king.
Kc6 improves the king without taking away every black reply.

Verify the final mating move
In the final position before mate, the black king is on a8 and White’s king on c6. Qb7# checks diagonally. The queen also controls a7 and b8, and the white king protects b7. Black cannot move, capture the queen or block an adjacent diagonal check.
Say those facts aloud before calling the move mate. A nearby queen without support would tell a different story. Mating patterns become dependable when you can explain why each defence fails.
The finish is only one of several possible edge patterns. Do not try to drag every position toward b7 specifically; rotate the idea to the edge your actual position gives you.
Qb7 is supported checkmate.
Position FEN
k7/3Q4/2K5/8/8/8/8/8 w - - 0 1Compare the tempting wrong square
From the same pre-mate position, Qc7 is stalemate. It controls Black’s escape squares but does not check a8. The extra queen is irrelevant once the game has ended as a draw.
This is the moment to use the two-question test: is the king checked, and does any legal reply remain? If neither is true, choose a different move. You can use the playback controls to compare Qb7 and Qc7 without changing the starting arrangement.
Do not conclude that a queen should always give check. Earlier quiet moves were useful. The restriction is to avoid removing the opponent’s last legal move without check, not to avoid quiet moves altogether.
Qc7 instead creates stalemate.
Position FEN
k7/3Q4/2K5/8/8/8/8/8 w - - 0 1Practise a method rather than a memorised line
Begin with the final three-piece net and verify the mate. Move the queen farther away and find a safe route back. Then move your king farther away and practise approaching while preserving a legal reply for the defender.
Each time, record one decision: what area did the queen restrict, what did the king add, or which stalemate did you avoid? This makes the practice transferable to a new starting position. Use Coach for repeated decisions and Chat when a move you expected to be mate leaves an escape.
Speed comes after reliability. If you can finish slowly without losing the queen or stalemating the king, reduce the time gradually. No particular number of practice sessions guarantees mastery or a rating result.
