    The king and queen vs. king checkmate is one of the most basic endgames in chess.

    Knowledge of this and other "overkill" endgames is crucial to improving your chess.

    After all, it isn't enough to gain a winning position -- you need to be able to checkmate

    your opponent's king.

    From the position above, White's first step should be to limit the Black king's area of

    movement. The queen is ideal at sealing the king into a small area.

    White can begin to limit Black's king by playing1. Qe5.

    Black's king is now boxed in, and will never advance to (or beyond) the marked squares

    in the diagram.

    This illustrates an important point: it is not always best to check the enemy king. It is

    often best to instead trap the king and limit its movement. Remember that checkmate is

    the goal, not simply random checks.

    is as good as any. How can White continue tomake progress towards limiting Black's king?

    With2. Qf6, White continues to limit the Black king's movements.

    White's next few moves will continue to follow this same strategy. Black will attempt to

    stay away from the edges of the board for as long as possible with moves such as2. ...

    Black's king will now have to move to either the a-file or the 8th rank. In either case,

    White has accomplished a major goal by driving the Black king to the edge of the board.

    For our example, Black will play4. ... Kc8.

    Once the enemy king has been pushed to an edge, it's important to make sure he stays

    there. We accomplish this by placing our queen on the "second line" - the rank or file

    next to the one on which the enemy king is trapped.

    For instance, in this example, the Black king has been forced to the 8th rank. On orderto ensure the king stays put, White correctly moves his queen to the 7th rank by

    playing5. Qe7.

    Black's king is now reduced to shuffling between c8, b8 and a8.

    The queen cannot checkmate an enemy king by herself. Instead, the king and queen

    must work together to finish the game.

    At this point, there's no need for White to move the queen again until he's ready to

    checkmate the Black king. Instead, he can bring his king closer to the action while Black

    is reduced to moving his king back and forth with moves like5. ... Kb8 6. Kc4 Kc8 7.

    Kc5, which brings us to the position diagrammed above.

    Black's only legal move is7. ... Kb8.

    A mate in one for White.

    Before executing the checkmate, the stronger side should move their king to the third

    line -- that is, two ranks or files away from the enemy king -- as near the enemy king as

    possible. When checkmating with a king and queen, having the kings directly opposing

    each other or separated by a "knight's move" will work.

    In the diagram above, white has accomplished this after8. Kb6 Kc8. White now has a

    checkmate in one move, which you should spot before continuing to the next page.

    White wins the game by playing9. Qc7#.As simple as this endgame may appear, there are a couple traps you should watch out

    for. Two stalemate possibilities exist, which can turn a certain win into a draw.
