In chess, the bishop and knight checkmate is the checkmate of a lone king by an opposing king, bishop, and knight.With the stronger side to move, checkmate can be forced in at most thirty-three moves from almost any starting position.
The bishop and knight mate is one of the four basic checkmates and occurs when the king works together with a bishop and knight to force the opponent king to the corner of the board. The bishop and knight endgame can be difficult to master: some positions may require up to 34 moves of perfect play before checkmate can be delivered.
Two knights endgame – endgame with two knights versus a lone king cannot force checkmate, but they may be able to force a win if the defender has a pawn. Wrong bishop – situation in some endgames where a player's bishop is on the wrong color of square to accomplish something, i.e. the result would be different if the bishop was on the other ...
Two basic checkmate positions are shown with a bishop and a knight, or the bishop and knight checkmate. [40] The first position is a checkmate by the bishop, with the black king in the corner. The bishop can be on other squares along the diagonal, the white king and knight have to be on squares that attack g8 and h7.

(rightmost diagram) Black is three pieces ahead, but if White is allowed to take the bishop, the two knights are insufficient to force checkmate. The only way to save the bishop is to move it, resulting in stalemate. A similar idea occasionally enables the inferior side to save a draw in the ending of bishop, knight, and king versus lone king.
In the example, if the knight on 85 moves to 73 and does not promote, it attacks the king and delivers checkmate (since the horse is also attacking the rank 2 squares in front of the king). However, if the knight moved to 73 and promoted to the gold-like narikeima, then the promoted knight isn't attacking the king leaving White a chance to ...
