The Tarrasch rule is a general principle that applies in the majority of chess middlegames and endgames. Siegbert Tarrasch (1862–1934) stated the "rule" that rooks should be placed behind passed pawns – either the player's or the opponent's. The idea behind the guideline is that (1) if a player's rook is behind their own passed pawn, the ...
The rook and pawn versus rook endgame is a fundamentally important, [2][3][4][5][6] widely studied [7][8] chess endgame. Precise play is usually required in these positions. With optimal play, some complicated wins require sixty moves [9] to either checkmate, capture the defending rook, or successfully promote the pawn. [10]
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 object of the game is to checkmate the opponent's king; checkmate occurs when a king is ...
Pawn (chess) The pawn (♙, ♟) is the most numerous and weakest piece in the game of chess. It may move one square directly forward, it may move two squares directly forward on its first move, and it may capture one square diagonally forward. Each player begins a game with eight pawns, one on each square of their second rank.
Table of graphs and parameters. 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 ...
Greco's mate is a common method of checkmating. The checkmate is named after the famous Italian checkmate cataloguer Gioachino Greco. It works by using the bishop to contain the black king by use of the black g-pawn and subsequently using the queen or a rook to checkmate the king by moving it to the edge of the board.
A pawn captures any opposing piece horizontally or vertically between the square to which the pawn moved and a friendly piece (i.e. there may be no gaps between any of the three pieces). This is considered a custodial form of capture because it has been likened to two men coming up on the sides of the person to be seized, and taking hold of his ...
h. White wins. 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] It is fundamental in the rook and pawn versus rook endgame. If the side with the pawn can reach this type of position ...
