Basic Checkmate
4. King, Knight & Bishop v King
- Overview -

Basic Checkmates - King and 2x Bishops v KingThis image shows an example of the sort of position a King, Knight & Bishop need to take up, to Checkmate a lone King.

Notice the formation of the winning Pieces ... White's King is flanked by the Knight on the outside of the board, while the Bishop on the inside is the piece that makes the attack, which wins the game.

The Role of the King (White's, in this example) is to remain on the same Rank, tracking the movement of the Knight as it makes its way across to the edge of the board (on the Queenside, in this example).

Like in all previous Basic Checkmate examples, the King's other role is to take advantage of the RULE that prevents the Kings from being on adjacent squares. I've likened this to the creation of an INVISIBLE WALL, which helps to BARRICADE the enemy King in, while the other Pieces do the checking and checkmating maneuvers, at the end.

The Role of the Knight is to stay within range of its own King, so it's not captured by the enemy King. The Knight will keep the last square guarded (b8, in this example), preventing the King from escaping the check that results in Checkmate.

The Role of the Bishop is to keep working like a terrier, nipping back and forth to prevent the enemy King from escaping, while gradually shepherding the King towards its Checkmate corner square (a8, in this example). The Bishop is the Piece that makes the check, which results in Checkmate (15. Bc6#).
