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 ...
The rook is worth about five pawns. In general, rooks are stronger than bishops or knights and are considered greater in value than either of those pieces by nearly two pawns, but less valuable than two minor pieces by approximately a pawn. Two rooks are generally considered to be worth slightly more than a queen (see chess piece relative value ...
Each player begins with sixteen pieces (but see the subsection below for other usage of the term piece).The pieces that belong to each player are distinguished by color: the lighter colored pieces are referred to as "white" and the player that controls them as "White", whereas the darker colored pieces are referred to as "black" and the player that controls them as "Black".
In graph theory, a rook's graph is an undirected graph that represents all legal moves of the rook chess piece on a chessboard. Each vertex of a rook's graph represents a square on a chessboard, and there is an edge between any two squares sharing a row (rank) or column (file), the squares that a rook can move between.
<footer> – the text which appears beneath the diagram, may be empty; optional – can be left out (currently not in the other templates) A square is defined by the name of piece or empty parameter. The names of the pieces are those given in algebraic notation: k = king; q = queen; r = rook; b = bishop; n = knight; p = pawn
In chess, the exchange is the material difference of a rook for a minor piece (i.e. a bishop or knight). Having a rook for a minor piece is generally advantageous, since the rook is usually more valuable. A player who has a rook for a minor piece is said to be up the exchange, and the other player is down the exchange.
Chess piece relative value – relative value of chess pieces, based on their relative power. Premove – used in fast online games, it refers to a player making his next move while his opponent is thinking about his move. After the opponent's move, the premove will be made, if legal, taking only 0.1 seconds on the game clock.
In a few cases, the superior side gives up their rook in order to promote the pawn, resulting in a winning queen versus rook position (see Pawnless chess endgame § Queen versus rook). A rule of thumb (with exceptions) is: if the king on the side without the pawn can reach the queening square of the pawn, the game is a draw ; otherwise it is a ...
