Elementary Chess Mates
An Elementary Checkmate occurs when a lone king is checkmated by the opposing king combined with one or more pieces. Pawns complicate the endgame significantly, and will not be discussed in this article. For clarity, in each example white will be taken as the attacker and black as the defender.
King and Two Rooks vs. King
This is the simplest and most intuitive of the Elementary Mates. White achieves this mate by pushing the black king back to the edge, row by row. A Queen could be substituted for either of the Rooks.
King and Queen vs. King
Unlike the previous example, the power of the white King must be employed to achieve victory. In this case the King supports the Queen, who delivers checkmate.
King and Rook vs. King
A King and Rook can't mate in the same way as the previous example. The White King must be used to block the squares on the 7th rank, while the rook delivers mate on the back rank. A Queen could be substituted for the Rook.
King and 2 Bishops vs. King
Two Bishops mate by working together to hem the black King into the corner. The white King must be used to block the enemy's escape up the side of the board.
King, Bishop and Knight vs. King
The King, Bishop and Knight vs. King endgame is the most difficult Elementary Mate to learn, as it requires precise maneuvering. Here are the two principals of the mate:
- The enemy King can only be mated in a corner that the Bishop can reach.
- The Knight must be used to control the squares that the Bishop can't cover.
The exact sequence of moves required to pull off this mate is beyond the scope of this article.
A Drawn Game - King and 2 Knights vs. King
The fact that this endgame is drawn can come as a surprise to novices. As the diagram shows, it is possible to set up a position on the board in which the lone king is checkmated. In practice, however, it is not possible to reach this situation against a reasonable defense.
