Practice chess endgames against Stockfish
Play the ending through to checkmate. Use hints, take back a move, and try another plan.
King and queen
Use your king and queen together to deliver checkmate. Leave the defending king a legal move until you are ready to mate.
You play White. The engine loads when you start. No account, clock, or rating required.

How the trainer works
- Choose a topic, then start a position. Click a white piece and one of its legal destinations.
- Stockfish replies for Black. Think about the opponent’s remaining squares before moving again.
- Use a clue or takeback when stuck. A draw is an opportunity to check what went wrong.
- Finish with checkmate. Review recorded moves in your history or download PGN.
The daily selection rotates at midnight in America/New_York, including daylight saving changes. It is chosen from this library, not a newly generated position every day.

Avoid the stalemate trap
A king with no legal move is only checkmated if it is also in check. Study the queen and king checkmate examples, or revisit the basic rules.
For a position from a finished game, use game review and save a moment to practice your own mistakes.
