Therefore the rook tries to be close to its king. The point is to capture the rook, mostly by a fork. The attacker should try to avoid those distances from the knight, in which it can attack pieces easily. Then the knight might try to prevent the mate, but finally it can only do so temporarily by sacrificing itself. The attacker needs to force the king to the edge of the board. Checkmate can be delivered also with the knight on the board, so capturing it is not neccessary. The attacker needs to force the king to the edge of the board (by near checks, with the support of the attacking king), and there the checkmate can be delivered. Checkmate can be delivered also with the bishop on the board, so capturing it is not neccessary – it is enough to avoid the bishop's field colour. The following table contains such pawnless endgames where both sides have pieces besides the king. The king needs to be forced to the corner using all the four pieces (for example well-cordinated knights can make a wall), and there they can easily deliver the checkmate. This is partially because of the fact that whenever a knight moves, it loses all controlled fields. Though the king can be forced to the corner, but it is then either stalemated, or is able to avoid being checkmated. Effecient coordination of the three pieces is required.įor more details, see: Wikipedia: Bishop and knight checkmate.Ĭheckmate exists, but cannot be forced. First the king has to be forced to the edge of the board (and it usually goes towards the wrong corner), then it has to be forced to the right corner, where the mate can be delivered. Checkmate can only be forced in the "right" corners, i.e which has the same field colour as the bishop moves on (in the other two corners, checkmate cannot be forced).

Then the three pieces can deliver the checkmate.įor more details, see: Wikipedia: Two bishops checkmate.ĭifficult mate. This area needs to be shrinked (with the support of the attacking king) until the king has only two squares in the corner. The two bishops standing on adjacent fields can close the defending king to a certain area. Precondition: the two bishops moves on different coloured fields (otherwise checkmating is not possible, not even if the opponent helps – but that case can only arise by pawn underpromotion or in chess variants). Then the rook and the king can deliver the checkmate.įor more details, see: Wikipedia: Rook checkmate.Ī single bishop and the king cannot deliver checkmate (not even if the opponent helps).Ī single knight and the king cannot deliver checkmate (not even it the opponent helps). The attacking king needs to support the rook meanwhile. The rook has to shrink the moving area of the king until it has only two squares in the corner.
