Queen and King checkmate is a checkmate pattern involving a two opposing kings and a queen on a blank board.

Step Instructions Diagrams

1

Position the queen so the queen and the opposing king are one square away in one orthogonal direction, and two squares away in the other perpendicular direction: a short "L". In other words, move your queen near the king so that if the king were a knight, it could capture the queen. If your queen is already at a square that satisfies this, then you can play a Waiting Move. f1 is a square that is 2 squares right and one square down of the black king.

2 (Repeat)

Let the enemy king move, then copy his relative move with your queen. Repeat this until the king is at the corner of the board, then move onto step 3. Top example, king moves one up one left, queen moves one up one left. King moves one up one right, so does queen.

2.1 (Note for 2)

If your queen reaches the board's edge and cannot copy the king anymore, move your queen to the closest square a knight's move away from the king. (Refer back to step 1). No waiting moves this time. f5, e6, e8 are squares that don't check the king. f5 is closest.

a b c d e f g h

3 (Only perform if necessary)

Move your queen to a square one square away from the king in one direction, and three squares away in the other direction, forming a long "L". This step is to prevent stalemate. If your queen is already on such a square, then skip this step. g5 and e7 are such squares, but the queen can only move to g5.

4 (Repeat)

Move your king to a square on the other side of the queen's barrier that the opposing king can't penetrate. Barrier is g8, g7, g6. King could move to f8, f7, f6.

5

Checkmate! Move the queen one square diagonal of the corner. Qg7#, g7 is square one left one down of h8.
