Chess Bishop and Knight Checkmate

In the diagram below, you will see that the squares the King would normally be able to move on are controlled by 3 white chess pieces.

1. The White King controls the diagonal square and the square between the White Knight and the Black King.

Knight and King Cause Checkmate

2. The White Bishop controls the square that the King is on.

3. The White Knight controls the last square available to the Black King.

To say it again: the White Bishop causes the check, and the positions of both the White King and the White Knight cause the Checkmate.

Summary:


A Queen with her King can Checkmate.
A single Rook can cause a Checkmate.
Two Bishops can force a Checkmate.
A Bishop and a Knight can Checkmate.

Further Important Information:


There are chess pieces that will never be able to checkmate.

A Bishop by itself, can not checkmate. The Bishop moves only on one color and the opponent King can always get away. All the hostile King has to do is occupy a space of a different color than the Bishop.

A Knight can not occupy every square that the opposite King can land on. The King can be safe if there is only one Knight. Remember too, that even if there are 2 Knights, they can not force a checkmate, the enemy King can always escape.
