The knight (♘, ♞) is a piece in the game of chess and is usually represented by a horse's head and neck, though other sets, especially Indian ones, have a full bodied horse. Each player starts with two knights, which are located between the rooks and bishops in the standard starting position.

The knight, along with the king and the rook, has the oldest defined movement of any chess piece, its movement being unchanged since the invention of chaturanga (ancient Indian strategy game) in India around the 6th century.

Compared to other chess pieces, the knight's movement is unique: it may move two squares vertically and one square horizontally, or two squares horizontally and one square vertically (with both forming the shape of an L). While moving, the knight can jump over pieces to reach its destination.
