The knight (♘, ♞) is a piece in the game of chess. It moves two squares vertically and one square horizontally, or two squares horizontally and one square vertically, jumping over other pieces. Each player starts the game with two knights on the b- and g-files, each located between a rook and a bishop.

A chess set consists of a chessboard and (nominally) 'white' and 'black' chess pieces for playing chess. There are sixteen pieces of each color: one king, one queen, two rooks, two bishops, two knights, and eight pawns. Extra pieces may be provided for use in pawn promotion, most commonly one extra queen per color. Chess boxes, chess clocks, and chess tables are common pieces of equipment used with chess sets. Chess sets are made in a wide variety of styles, sometimes for ornamental rather than practical purposes. For tournament play, the Staunton chess set is preferred and, in some cases, required.
Human chess uses people (often in costumes) as the pieces. Blindfold chess may be played without any set at all.
Chess is a board game for two players. It is an abstract strategy game that involves no hidden information and no elements of chance. It is played on a square board consisting of 64 squares arranged in an 8×8 grid. The players, referred to as "White" and "Black", each control sixteen pieces: one king, one queen, two rooks, two bishops, two knights, and eight pawns, with each type of piece having a different pattern of movement. An enemy piece may be captured (removed from the board) by moving one's own piece onto the square it occupies. The object of the game is to "checkmate" (threaten with inescapable capture) the enemy king. There are also several ways a game can end in a draw.
The recorded history of chess dates back to the emergence of chaturanga in 7th century India. Chaturanga is also thought to be an ancestor of similar games like Janggi, xiangqi and shogi. After its introduction to Persia, it spread to the Arab world and then to Europe. The modern rules of chess emerged in Europe at the end of the 15th century, becoming standardized and gaining universal acceptance by the end of the 19th century. Today, chess is one of the world's most popular games, with millions of players worldwide.
A chess piece, or chessman, is a game piece that is placed on a chessboard to play the game of chess. It can be either white or black, and it can be one of six types: king, queen, rook, bishop, knight, or pawn.
Chess sets generally come with sixteen pieces of each color. Additional pieces, usually an extra queen per color, may be provided for use in promotion or handicap games.
The White Knight is a fictional character in Lewis Carroll's 1871 book Through the Looking-Glass. He represents the chess piece of the same name. As imagined in John Tenniel's illustrations for the Alice stories, he is inspired by Albrecht Dürer's 1513 engraving "Knight, Death and the Devil."
The Staunton chess set is the standard style of chess pieces, recommended for use in competition since 2022 by FIDE, the international chess governing body.
The English journalist Nathaniel Cooke is credited with the design on the patent, and the design is named after the leading English chess master Howard Staunton, who endorsed it; the first 500 sets were numbered and hand-signed by Staunton. This style of set was first made available by Jaques of London in 1849, and it quickly became the standard. The set style and its variations have been used around the world since.
In chess, promotion is the replacement of a pawn with a new piece when the pawn is moved to its last rank. The player replaces the pawn immediately with a queen, rook, bishop, or knight of the same color. The new piece does not have to be a previously captured piece. Promotion is mandatory when moving to the last rank; the pawn cannot remain as a pawn.
Promotion to a queen is known as queening; promotion to any other piece is known as underpromotion. Promotion is almost always to a queen, as it is the most powerful piece. Underpromotion might be done for various reasons, such as to avoid stalemate or for tactical reasons related to the knight's unique movement pattern. Promotion or the threat of it often decides the result in an endgame.
