Benoni Defense
The Benoni Defense is a chess opening characterized by an early reply of ...c5 against White's opening move 1.d4. Most commonly, it is reached by the sequence: :1. d4 Nf6 :2. c4 c5 :3. d5 Black can then sacrifice a pawn with 3...b5 (the Benko Gambit), otherwise 3...e6 is the most common move. (3...d6 or 3...g6 are also seen, typically transposing to main lines.) The Old Benoni Defense is characterized by :1. d4 c5 This will usually transpose into a main line after 2.d5, but Black has other options such as an early ...f5. Etymology '' Benoni'' (or "Ben-Oni") is an ancient Hebrew name, still occasionally used, meaning "son of my sorrow". It is a reference to the Biblical account of the dying Rachel giving birth to Benjamin, whom she named Ben-OniGenesis 35:18 In 1825 Aaron Reinganum, a prominent member of the Frankfurt Jewish community, published a book entitled ''Ben-Oni oder die Vertheidigungen gegen die Gambitzüge im Schache'' in which he analyzed several defen ...

Chess Opening
A chess opening or simply an opening is the initial stage of a chess game. It usually consists of established theory; the other phases are the middlegame and the endgame. Many opening sequences have standard names such as the "Sicilian Defense". ''The Oxford Companion to Chess'' lists 1,327 named openings and variants, and there are many others with varying degrees of common usage. Opening moves that are considered standard are referred to as "book moves", or simply "book". When a game begins to deviate from known opening theory, the players are said to be "out of book". In some openings, "book" lines have been worked out for over 30 moves, as in the classical King's Indian Defense and in the Najdorf variation of the Sicilian Defense. Professional chess players spend years studying openings, and continue doing so throughout their careers, as opening theory continues to evolve. Players at the club level also study openings but the importance of the opening phase is smaller t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chess Opening Theory/1
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 ...

Encyclopaedia Of Chess Openings
The ''Encyclopaedia of Chess Openings'' () is a reference work describing the state of opening theory in chess, originally published in five volumes from 1974 to 1979 by the Serbian company Šahovski Informator (Chess Informant). It is currently undergoing its fifth edition. ''ECO'' may also refer to the opening classification system used by the encyclopedia. Overview Both ''ECO'' and ''Chess Informant'' are published by the Belgrade-based company Šahovski Informator. The moves are taken from thousands of master games and from published analysis in ''Informant'' and compiled by the editors, most of whom are grandmasters, who select the lines which they consider most relevant or critical. The chief editor since the first edition has been Aleksandar Matanović. The openings are provided in an ''ECO'' table that concisely presents the opening lines considered most critical by the editors. ''ECO'' covers the openings in more detail than rival single volume publications such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Half-open File
In chess, a half-open file (or semi-open file) is a with pawns of only one color. The half-open file can provide a line of attack for a player's rook or queen. A half-open file is generally exploited by the player with no pawns on it. Many openings, such as the Sicilian Defense, aim to complicate the position. In the main line Sicilian, 1.e4 c5 2.Nf3 d6 (or 2...e6, or 2...Nc6) 3.d4 cxd4 4.Nxd4, White obtains a half-open d-file, but Black can pressure White along the half-open c-file. In positions where White has no pawns on a file but Black has one pawn or more on that file, the position is considered to be half-opened for white. During instances where Black has zero pawns on a file but White has one or more pawns on that file, the position is considered to be half-opened for black. In such instances where pawns capture or advance, in a way that it opens or half-opens a file or files, this instance is called a pawn break. The demolition of the pawn structure is a common th ...

World Chess Champion
The World Chess Championship is played to determine the world champion in chess. The current world champion is Magnus Carlsen of Norway, who has held the title since 2013. The first event recognized as a world championship was the 1886 match between the two leading players in the world, Wilhelm Steinitz and Johannes Zukertort. Steinitz won, becoming the first world champion. From 1886 to 1946, the champion set the terms, requiring any challenger to raise a sizable stake and defeat the champion in a match in order to become the new world champion. Following the death of reigning world champion Alexander Alekhine in 1946, FIDE (the International Chess Federation) took over administration of the World Championship, beginning with the 1948 World Championship tournament. From 1948 to 1993, FIDE organized a set of tournaments to choose a new challenger every three years. In 1993, reigning champion Garry Kasparov broke away from FIDE, which led to a rival claimant to the title of W ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alexander Alekhine
Alexander Aleksandrovich Alekhine, ''Aleksándr Aleksándrovich Alékhin''; (March 24, 1946) was a Russian and French chess player and the fourth World Chess Champion, a title he held for two reigns. By the age of 22, Alekhine was already among the strongest chess players in the world. During the 1920s, he won most of the tournaments in which he played. In 1921, Alekhine left Soviet Russia and emigrated to France, which he represented after 1925. In 1927, he became the fourth World Chess Champion by defeating José Raúl Capablanca. In the early 1930s, Alekhine dominated tournament play and won two top-class tournaments by large margins. He also played first board for France in five Chess Olympiads, winning individual prizes in each (four medals and a brilliancy prize). Alekhine offered Capablanca a rematch on the same demanding terms that Capablanca had set for him, and negotiations dragged on for years without making much progress. Meanwhile, Alekhine defended his title wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Benko Gambit
The Benko Gambit (or Volga Gambit) is a chess opening characterised by the move 3...b5 in the Benoni Defence arising after: :1. d4 Nf6 :2. c4 c5 :3. d5 b5 Black sacrifices a pawn for enduring pressure. White can accept or decline the gambit pawn. The ''Encyclopaedia of Chess Openings'' has three codes for the Benko Gambit: * A57 3...b5 * A58 3...b5 4.cxb5 a6 5.bxa6 * A59 3...b5 4.cxb5 a6 5.bxa6 Bxa6 6.Nc3 d6 7.e4 Origin and predecessors The idea of sacrificing a pawn with ...b5 and ...a6 is quite old. Karel Opočenský applied the idea against, among others, Gideon Ståhlberg at Poděbrady 1936, Paul Keres at Pärnu 1937, Erich Eliskases at Prague 1937, and Theo van Scheltinga at the Buenos Aires Chess Olympiad 1939. Later, the game Mark Taimanov–David Bronstein at the Candidates Tournament, Zürich 1953, drew attention. Most of these games began as a King's Indian, with Black only later playing ...c5 and ...b5.

''The Oxford Companion to Chess'' lists 1,327 named openings and variants. Chess players' names are the most common sources of opening names.
