In chess, a relative value (or point value) is a standard value conventionally assigned to each piece. Piece valuations have no role in the rules of chess but are useful as an aid to evaluating a position. The best-known system assigns 1 point to a pawn, 3 points to a knight or bishop, 5 points to a rook and 9 points to a queen. Valuation ...
A bishop and knight can force mate, but with far greater difficulty than two bishops. In certain positions a bishop can by itself lose a move (see triangulation and tempo), while a knight can never do so. The bishop is capable of skewering or pinning a piece, while the knight can do neither. A bishop can in some situations hinder a knight from ...
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 standard valuation is one point for a pawn, three points for a knight or bishop, five points for a rook, and nine points for a queen. [8] These values are reliable in endgames, particularly with a limited number of pieces. But these values can change depending on the position or the phase of the game (opening, middle game, or ending).
In most chess positions, a bishop is worth slightly more than a knight because of its longer range of movement. As a chess game progresses, pawns tend to get traded, removing support points from the knight and opening up lines for the bishop. This generally leads to the bishop's advantage increasing over time.
Staunton style chess pieces. Left to right: king, rook, queen, pawn, knight, bishop. The rules of chess (also known as the laws of chess) govern the play of the game of chess. Chess is a two-player abstract strategy board game. Each player controls sixteen pieces of six types on a chessboard. Each type of piece moves in a distinct way.
Non-capturing move: A move without capture is notated by the piece's name, a hyphen and the destination square, e.g. Kt–QB3 (knight to queen's bishop 3) and P–QN4 (pawn to queen's knight 4). Capture: A capture is notated by the piece's name, a cross (×), and the name of the piece captured, e.g. Q×N (queen captures knight).
Checkmate can be forced with a bishop and knight, however, or with two bishops, even though the bishop and knight are in general about equal in value. Paradoxically, checkmate with two knights sometimes can be forced if the weaker side has a single extra pawn, but this is a curiosity of little practical value (see two knights endgame ).
