Checkmate

The object of the game is to threaten the opponent's king in such a way that escape is not possible (checkmate).
Checkmate (often shortened to mate) is a game position in chess and other chess-like games in which a player's king is in check (threatened with ) and there is no way to remove the threat.

Check (chess)

If a player's king is threatened with capture, it is said to be in check, and the player must remove the threat of on the next move.
A check is a condition in chess, shogi, and xiangqi that occurs when a player's king (or general in xiangqi) is under threat of on their opponent's next turn.

Queen (chess)

Opposition (chess)

opposition
As a result, opposing kings may never occupy adjacent squares (see opposition), but the king can give discovered check by unmasking a bishop, rook, or queen.
In chess, opposition (or direct opposition) is the situation occurring when two kings face each other on a rank or file, with only one square in-between them.

Bishop (chess)

Chess endgame

endgameendgamesending
Although the king is the most important piece, it is usually the weakest piece in the game until a later phase, the endgame. In the endgame, however, the king emerges to play an active role as an offensive piece as well as assisting in the promotion of their remaining pawns.
The king, which has to be protected in the middlegame owing to the threat of checkmate, becomes a strong piece in the endgame.

Chess middlegame

middlegamemiddle gamemiddlegames
In the opening and middlegame, the king will rarely play an active role in the development of an offensive or defensive position.
Simply put, the middle game begins when both players have completed the development of all or most of their pieces and the king has been brought to relative safety.

Draw (chess)

Exchange (chess)

exchangeexchangesexchanged
It is not meaningful to assign a value to the king relative to the other pieces, as it cannot be captured or exchanged.
Any types of pieces except the kings may possibly be exchanged, i.e. captured in an exchange, although a king can capture an opponent's piece.

Knight (chess)

knightknightsKnight's Move
A piece is interposed between the king and the attacking piece to break the line of threat (not possible when the attacking piece is a knight or pawn, or when in double check).
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 in India around the 6th century.

Chess piece relative value

pointsvalueschess piece value
As an assessment of the king's capability as an offensive piece in the endgame, it is often considered to be slightly stronger than a bishop or knight – Emanuel Lasker gave it the value of a knight plus a pawn (i.e. four points on the scale of chess piece relative value).
The value of the king is undefined as it cannot be captured, let alone traded, during the course of the game.

Promotion (chess)

In the endgame, however, the king emerges to play an active role as an offensive piece as well as assisting in the promotion of their remaining pawns.
In variants where there are no royal pieces (i.e. the objective of the game is not checkmate), such as suicide chess, promotions to king may be permitted.
