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]).
While king and rook vs. king can force checkmate, king and nightrider vs. king cannot checkmate at all. The nightrider, like the knight, can jump over blockades in closed positions and is good at delivering forks. The nightrider can triangulate while the knight cannot. King, nightrider, and knight vs. king can force checkmate.
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.
In an endgame where one side has only a king and a knight while the other side has only a king, the game is a draw since a checkmate is impossible. When a lone king faces a king and two knights, a checkmate can never be forced ; checkmate can occur only if the opponent commits a blunder by moving their king to a square where it can be ...
There are also positions in which a king and a knight can checkmate a king and a bishop, knight, or rook; or a king and a bishop can checkmate a king with a bishop on the other color of squares or with a knight, but the checkmate cannot be forced if there is no other material on the board (see the diagrams for some examples).

With Delétang's triangle method, White confines the black king into a series of shrinking triangles; the bishop controls the hypotenuse of each triangle, while the knight and king control other squares that prevent the black king's escape. The winning procedure consists of forcing the king to move towards the corner so that the bishop can ...

After the en passant capture, three pieces discover-check the black king: the pawn, the knight-rider, and the rook. Black would now be obliged to escape the multi-check by ...
The camel by itself is worth about two pawns (appreciably less than a knight) because of its colorboundedness and lack of sufficient freedom of movement on an 8×8 board. . However, a king, a bishop, and a camel can force checkmate on a bare king, assuming that the bishop and the camel are not on the same square color; [4] a king, a knight, and a camel can usually force checkmate on a bare ...
