Queen and king against king

The endgame you will meet most — and the stalemate trap that costs the game once in a lifetime.

This is the endgame you will meet most often: you promoted a pawn and you have a queen against a lone king. Careful — it is also the endgame beginners botch most.

The box method. Do not hunt for mate straight away. The queen controls an enormous area: place her a knight’s move away from the enemy king, and his box shrinks with every move. He is left with a smaller and smaller square. Once he is against the edge, bring your own king up and the mate arrives by itself.

⚠️ The stalemate trap. If the enemy king has no legal move and is not in check, the game is a draw. You were a queen up and you do not win. It happens to everyone once — and only once, because you remember it.

    Start

    Black to move. The king cannot go to a7, b7 or b8: the queen covers everything. He is not in check. Draw.

    The rule that protects you: before you play a queen move, look at what the enemy king has left. If he has nothing, your move is wrong — unless he is in check.

      Start

      Here the queen mates because the white king protects her. A lone queen never mates.

      Remember this too: a lone queen never mates. Your king always has to take part.

      Play your move on the board: drag a piece, or tap it and then tap its destination square.

      Standard notation (Bc4, Nxe5, O-O) or plain squares (f1c4). French piece letters work too: R king, D queen, T rook, F bishop, C knight.
