The rook cannot jump over pieces. The rook may capture an enemy piece by moving to the square on which the enemy piece stands, removing it from play. The rook also participates with the king in a special move called castling, wherein it is transferred to the square crossed by the king after the king is shifted two squares toward the rook.
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.
The rook polynomial R m,n (x) corresponds to the complete bipartite graph K m,n . The rook polynomial of a general board B ⊆ B m,n corresponds to the bipartite graph with left vertices v 1, v 2, ..., v m and right vertices w 1, w 2, ..., w n and an edge v i w j whenever the square (i, j) is allowed, i.e., belongs to B. Thus, the theory of ...
In Rome, from the early 17th century until the late 19th century, the rook might be placed on any square up to and including the king's square, and the king might be moved to any square on the other side of the rook. This was called free castling. In the 1811 edition of his chess treatise, Johann Allgaier introduced the 0-0 notation. He ...
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.
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 ...
The checkmate is delivered by a rook with the queen's assistance. The rook is adjacent to the king, while the queen supports the rook, being separated from it by one empty square on the same diagonal as the rook. This forms a 3 by 3 box shape, inside which the enemy king is trapped.
The Lucena position is a position in chess endgame theory where one side has a rook and a pawn and the defender has a rook. Karsten Müller said that it may be the most important position in endgame theory. [1]
