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] |
Chess Kll45
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, two bi ...

John Nunn
John Denis Martin Nunn (born 25 April 1955) is an English chess grandmaster, a three-time world champion in chess problem solving, a chess writer and publisher, and a mathematician. He is one of England's strongest chess players and was formerly in the world's top ten. Education and early life Nunn was born in London. As a junior, he showed a prodigious talent for the game and in 1967, at twelve years of age, he won the British under-14 Championship. At fourteen, he was London Under-18 Champion for the 1969–70 season and less than a year later, at just fifteen years of age, he proceeded to Oriel College, Oxford, to study mathematics. At the time, Nunn was Oxford's youngest undergraduate since Cardinal Wolsey in 1520. Graduating in 1973, he went on to gain his Doctor of Philosophy degree in 1978 with a thesis on finite H-spaces supervised by John Hubbuck. Nunn remained in Oxford as a mathematics lecturer until 1981, when he became a professional chess player. Career In 19 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Siegbert Tarrasch
Siegbert Tarrasch (; 5 March 1862 – 17 February 1934) was a German chess player, considered to have been among the strongest players and most influential theoreticians of the late 19th and early 20th century. Life Tarrasch was born in Breslau, in what was then Prussian Silesia and now is Poland. Having finished school in 1880, he left Breslau to study medicine in Berlin and then in Halle. With his family, he settled in Nuremberg, Bavaria, and later in Munich, setting up a successful medical practice. He had five children. Tarrasch was Jewish, converted to Christianity in 1909, and was a patriotic German who lost a son in World War I, yet he faced antisemitism in the early stages of the Third Reich. Chess career A medical doctor by profession, Tarrasch may have been the best player in the world in the early 1890s. He scored heavily against the ageing World Champion Wilhelm Steinitz in tournaments (+3−0=1) but refused an opportunity to challenge Steinitz for the world tit ...

King And Pawn Versus King Endgame
The chess endgame with a king and a pawn versus a king is one of the most important and fundamental endgames, other than the basic checkmates. It is an important endgame for chess players to master, since most other endgames have the potential of reducing to this type of endgame via exchanges of pieces. Players need to be able to determine quickly whether a given position is a win or a draw, and to know the technique for playing it. The crux of this endgame is whether or not the pawn can be promoted (or queened), so checkmate can be forced. In the first paragraph of one of his books on endgames, Peter Griffiths emphasized the importance of this endgame: There is simply no substitute to a clear understanding of when and how these positions are won or drawn, not only so that one can play them accurately, but in order to recognize in advance what the correct result should be. If you can do that, you can exchange off quite confidently from a more complex position. In the positio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

José Capablanca
José is a predominantly Spanish and Portuguese form of the given name Joseph. While spelled alike, this name is pronounced differently in each language: Spanish ; Portuguese (or ). In French, the name ''José'', pronounced , is an old vernacular form of Joseph, which is also in current usage as a given name. José is also commonly used as part of masculine name composites, such as José Manuel, José Maria or Antonio José, and also in female name composites like Maria José or Marie-José. The feminine written form is ''Josée'' as in French. In Netherlandic Dutch, however, ''José'' is a feminine given name and is pronounced ; it may occur as part of name composites like Marie-José or as a feminine first name in its own right; it can also be short for the name ''Josina'' and even a Dutch hypocorism of the name ''Johanna''. In England, Jose is originally a Romano-Celtic surname, and people with this family name can usually be found in, or traced to, the English county of C ...

Check (chess)
In chess and similar games, check is a condition that occurs when a player's king is under threat of on the opponent's next turn. A king so threatened is said to be in check. A player must get out of check if possible by moving the king to a safe square, interposing a piece between the threatening piece and the king, or capturing the threatening piece. If the player cannot get out of check by any of these options, the game ends in checkmate, and the player loses. Players cannot make any move that puts their own king in check. Many chess variants feature check, such as shogi, xiangqi, and janggi. Overview A check is the result of a move that places the opposing king under an immediate threat of capture by one (or occasionally two) of the player's pieces. Making a move that checks is sometimes called "giving check". Even if a piece is pinned against the player's own king, it may still give check. For example, in the diagrammed position, White has just played Be4+, simultane ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Optimal Play
In game theory, the best response is the strategy (or strategies) which produces the most favorable outcome for a player, taking other players' strategies as given (; ). The concept of a best response is central to John Nash's best-known contribution, the Nash equilibrium, the point at which each player in a game has selected the best response (or one of the best responses) to the other players' strategies . Correspondence Reaction correspondences, also known as best response correspondences, are used in the proof of the existence of mixed strategy Nash equilibria (, Section 1.3.B; , Section 2.2). Reaction correspondences are not "reaction functions" since functions must only have one value per argument, and many reaction correspondences will be undefined, i.e., a vertical line, for some opponent strategy choice. One constructs a correspondence b(\cdot), for each player from the set of opponent strategy profiles into the set of the player's strategies. So, for any given set o ...

Algebraic Notation (chess)
Algebraic notation (or AN) is the standard method for recording and describing the moves in a game of chess. It is based on a system of coordinates to uniquely identify each square on the chessboard. It is used by most books, magazines, and newspapers. In English-speaking countries, the parallel method of descriptive notation was generally used in chess publications until about 1980. A few players still use descriptive notation, but it is no longer recognized by FIDE, the international chess governing body. Algebraic notation exists in various forms and languages and is based on a system developed by Philipp Stamma. Stamma used the modern names of the squares, but he used p for pawn moves and the original of a piece (a through h) instead of the initial letter of the piece name. The term "algebraic notation" may be considered a misnomer, as the system is unrelated to algebra. Other terms such as "standard notation" and "coordinate notation" have been proposed, but the traditional ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
