The knight (♘, ♞) is a piece in the game of chess, represented by a horse's head and neck.It moves two squares vertically and one square horizontally, or two squares horizontally and one square vertically, jumping over other pieces.
A knight's tour is a sequence of moves of a knight on a chessboard such that the knight visits every square exactly once. If the knight ends on a square that is one knight's move from the beginning square (so that it could tour the board again immediately, following the same path), the tour is closed (or re-entrant); otherwise, it is open.

In graph theory, a knight's graph, or a knight's tour graph, is a graph that represents all legal moves of the knight chess piece on a chessboard.Each vertex of this graph represents a square of the chessboard, and each edge connects two squares that are a knight's move apart from each other.
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]).
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.
