In general, the attacker can force stalemate but not checkmate. [24] Rook versus a knight: This is usually a draw. There are two main exceptions: the knight is separated from the king and may be trapped and won or the king and knight are poorly placed. [25] [26] Kamsky vs Bacrot, 2006 is an example of a rook vs knight ending which resulted in a ...
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).

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]).
If it gets to one of the squares marked with "x", the king can move next to the pawn and the rook can capture the pawn for a draw. Otherwise, the king needs to stay on the squares marked with dots: g7 and h7. The reason is that if the black king is on another rank, the white rook can check and then the pawn promotes and wins.
Each type of piece moves in a distinct way. The object of the game is to checkmate the opponent's king; checkmate occurs when a king is threatened with capture and has no escape. A game can end in various ways besides checkmate: a player can resign, and there are several ways a game can end in a draw.
In Anastasia's mate, a knight and rook team up to trap the opposing king between the side of the board on one side and a friendly piece on the other. Often, the queen is first sacrificed along the a-file or h-file to achieve the position. A bishop can be used instead of a knight to the same effect (see Greco's mate).
While the other basic checkmates [a] can be forced in O moves on an n × n board, Telesin's method gives an O(n 2) bound for a bishop and knight checkmate, though it has not been proven whether this is optimal. [9] [10]
A knight can draw against three connected pawns if none are beyond their fourth rank. [67] Rook versus pawns: If the rook's king is not near, one pawn draws and two pawns win. If the rook's king is near, the rook wins over one or two pawns and draws against three. Four pawns usually win but the rook may be able to draw, depending on their position.
