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 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.
The two knights endgame is a chess endgame with a king and two knights versus a king. In contrast to a king and two bishops (on opposite-colored squares), or a bishop and a knight, a king and two knights cannot force checkmate against a lone king (however, the superior side can force stalemate [1] [2]).
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 ...
If White has bishop and knight, and Black has a rook, the endgame is classified KBNKR. KNBKR would not be standard. KNBKR would not be standard. In positions with two or more bishops on the board, a "bishop signature" may be added to clarify the relationship between the bishops.
If, however, there are two Knights and one Bishop opposed to a Rook, the latter may generally be exchanged for the Bishop, and as two Knights are insufficient of themselves to force checkmate, the game will be drawn." Modern-day endgame tablebases confirm Staunton's assessments of both endings. [89]
Being a five-piece endgame, the rook and bishop versus rook endgame has been fully analysed using computers. Endgame tablebases show that 40.1% of the legal positions with this material are theoretical wins, but that includes many unnatural positions that are unlikely to occur in games.
