It served to combine the rook's move and the king's jumping move into a single move. [16] 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.
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.
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.
The key in the puzzle on the right is 1. Qd2. This move has no threat, but it leaves black in zugzwang: Black must either move one of his bishops or rooks, or move a pawn. However, any bishop or rook move must unguard one of the squares of d5, d6, d7 or d8, allowing White to mate on d5, d6 or d7 with the queen, and d8 with the knight. The lines ...
Rook: In the corners, at a1, l1, a8, and l8 stands the rook, [2] which moves any number of squares orthogonally (the same as its modern chess counterpart). Pawn: The second rank for each player is filled with pawns , which move like modern chess pawns, one square forward and capture one square diagonally forward.
A move can be both check and garde simultaneously. Before the queen acquired its current move (about 1495) the rook was the most powerful piece. At that time the term check-rook was used for a move that checked the king and attacked a rook at the same time (Hooper & Whyld 1992:75).
Here, the rook can move in forward direction determined by its ring (to any white dot). It has two sideways moves (yellow dots), and one backward move (green dot) available. The bishop can move to any gray dot, including one rebound off g4. It has two backward move options (green dots).
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.
