Double knight mate

In a double knight mate, one knight attacks the king and the other controls one or more squares the king could use to escape. Because knights jump and attack in an L shape, their shared coverage is less visually obvious than a rook or bishop line.

The pattern often appears with the king on an edge or in a corner, where its own pieces already occupy some exits. One knight may drive the king into the final area and the other completes the mate. Check each square separately because knight attacks do not create continuous barriers.

The f7-h8 jump is the direct attack on the king.

One knight checks, the other seals

The knight on f7 gives check. The knight on f6 controls g8 and h7, and the black pawn on g7 occupies the only remaining square.

1. The f7-h8 jump is the direct attack on the king.
2. The knight on f6 covers g8 and h7 with two separate L-shaped attacks.
3. Black's own pawn occupies g7 and completes the confinement.

The name describes a specific mating position, not a general method for winning an endgame, the stage in which few pieces remain. Two knights cannot force mate against a lone king when the defender plays correctly. In practical positions, the defender's pawns or pieces can remove the escape squares that would otherwise prevent mate.
