Tarrasch Rule
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 his passed pawn, the rook protects it as it advances, and (2) if it is behind an opponent's passed pawn, the pawn cannot advance unless it is protected along its way. The original quote came from his famous book about the St. Petersburg 1914 chess tournament, which was translated into English in 1993: :The rooks belong ''behind'' passed pawns, behind their own in order to support their advance, behind the enemy's in order to impede their advance.Tarrasch, ''St Petersburg 1914: International Chess Tournament'', translated by Dr Robert Maxham, Caissa Editions, Yorklyn, DE, 1993, —comment oFrank James Marshall vs Emanuel Lasker, St. Petersburg (1914), rd 3, Apr-24 p ...

Chess Rll45
Chess is a board game for two players, called White and Black, each controlling an army of chess pieces in their color, with the objective to checkmate the opponent's king. It is sometimes called international chess or Western chess to distinguish it from related games, such as xiangqi (Chinese chess) and shogi (Japanese chess). The recorded history of chess goes back at least to the emergence of a similar game, chaturanga, in seventh-century India. The rules of chess as we know them today emerged in Europe at the end of the 15th century, with standardization and universal acceptance by the end of the 19th century. Today, chess is one of the world's most popular games, played by millions of people worldwide. Chess is an abstract strategy game that involves no hidden information and no use of dice or cards. It is played on a chessboard with 64 squares arranged in an eight-by-eight grid. At the start, each player controls sixteen pieces: one king, one queen, two rooks, ...

Rook And Pawn Versus Rook Endgame
The rook and pawn versus rook endgame is a fundamentally important, widely studied chess endgame. Precise play is usually required in these positions. With optimal play, some complicated wins require sixty moves to either checkmate, capture the defending rook, or successfully promote the pawn. In some cases, thirty-five moves are required to advance the pawn once. The play of this type of ending revolves around whether or not the pawn can be promoted, or if the defending rook must be sacrificed to prevent promotion. If the pawn promotes, that side will have an overwhelming advantage. If the pawn is about to promote, the defending side may give up their rook for the pawn, resulting in an easily won endgame for the superior side (a basic checkmate). 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 kin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Stalemate
Stalemate is a situation in the game of chess where the player whose turn it is to move is not in check and has no legal move. Stalemate results in a draw. During the endgame, stalemate is a resource that can enable the player with the inferior position to draw the game rather than lose. In more complex positions, stalemate is much rarer, usually taking the form of a swindle that succeeds only if the superior side is inattentive. Stalemate is also a common theme in endgame studies and other chess problems. The outcome of a stalemate was standardized as a draw in the 19th century. Before this standardization, its treatment varied widely, including being deemed a win for the stalemating player, a half-win for that player, or a loss for that player; not being permitted; and resulting in the stalemated player missing a turn. Stalemate rules vary in other games of the chess family. Etymology and usage The first recorded use of stalemate is from 1765. It is a compounding of Middl ...
