Basic Checkmate
3. King & 2x Bishops v King
- Overview -

This image shows an example of the sort of position a King & 2x Bishops need to take up, to Checkmate a lone King.

For this to work, the enemy King must be pushed into one of the corner squares (h8, in this example).

The victorious King is used to prevent the enemy King escaping along the flank, taking advantage of the RULE that Kings cannot sit on adjacent squares.

In the diagram (above) imagine there's an INVISIBLE WALL at squares
f7-g7-h7, which help BARRICADE the enemy King on his back rank.

The Bishops cannot protect one another, so they must be moved cautiously, once in enemy territory.

Depending on which corner you trap the enemy King, the Bishop closest to the enemy's back rank will work to close off the final escape square (Be6 closes off the g8-square, in this example). The other Bishop will sit in the Center and directly check the enemy King, for the Checkmate win.
