The rook (/ r ʊ k /; ♖, ♜) is a piece in the game of chess. It may move any number of squares horizontally or vertically without jumping, and it may capture an enemy piece on its path; it may participate in castling. Each player starts the game with two rooks, one in each corner on their side of the board.
By chess problem convention, if a player's king and rook are on their original squares, the player is assumed to have castling rights unless it can be proved otherwise. [42] In some retrograde analysis problems, the solver (who usually plays White) is required to prove that the opponent has previously moved their king or rook and therefore ...
A rook moves as the rook in the tri-chess two-player game. (Namely, in six directions along horizontal ranks or oblique files.) A knight moves in the pattern: two steps as a bishop, then one step as a rook in an orthogonal direction. A knight leaps any intervening men. The chancellor moves as a rook and knight. The cardinal moves as a 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.
The king is the most valuable piece—it is illegal to play any move that puts one's king under attack by an opponent piece. A move that attacks the king must be parried immediately; if this cannot be done, the game is lost. (See § Check and checkmate.) A rook can move any number of squares along a rank or file. A rook is involved in the king ...
In the first diagram with White to play, White can force checkmate as follows: 1. Rxg7+ Kh8 2. Rxh7+ Kg8 3. Rbg7# For this type of mate, the rooks on White's 7th rank can start on any two files from a to e, and although black pawns are commonly present as shown, they are not necessary to deliver the mate. The second diagram shows the final ...
The queen versus rook endgame is a chess endgame where one player has just a king and queen, and the other player has just a king and rook. As no pawns are on the board, it is a pawnless chess endgame .
The following outline is provided as an overview of and topical guide to chess: Chess is a two-player board game played on a chessboard (a square-checkered board with 64 squares arranged in an eight-by-eight grid). In a chess game, each player begins with sixteen pieces: one king, one queen, two rooks, two knights, two bishops, and eight pawns.
