List Of Chess Openings
This is a list of chess openings, organized by the ''Encyclopaedia of Chess Openings'' () code. In 1966, Chess Informant categorized the chess openings into five broad areas ("A" through "E"), with each of those broken down into one hundred subcategories ("00" through "99"). The openings were published in five volumes of ''ECO'', with volumes labeled "A" through "E". This is a list of chess openings by the ''ECO'' classification. A – Flank openings * White first moves other than 1.e4, 1.d4 (A00–A39) * 1.d4 without 1...d5, 1...Nf6 or 1...f5: Atypical replies to 1.d4 (A40–A44) * 1.d4 Nf6 without 2.c4: Atypical replies to 1...Nf6 (A45–A49) * 1.d4 Nf6 2.c4 without 2...e6 or 2...g6: Atypical Indian systems (A50–A79) * 1.d4 f5: Dutch Defence (A80–A99) A00–A39 White first moves other than 1.e4, 1.d4: *A00 Irregular Openings :* Anderssen's Opening: 1.a3 ::* Anderssen's Opening, Polish Gambit: 1...a5 2.b4 :::* Bugayev Attack 2...e5 ::* Anderssen's Opening, Creepy Crawly ...

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] |
Clemenz Opening
The Clemenz Opening is a chess opening beginning with the move: :1. h3 This opening is named after Hermann Clemenz (1846–1908), an Estonian player. It is considered an irregular opening, and is classified under the code A00 (miscellaneous first moves by White) in the ''Encyclopaedia of Chess Openings''. Discussion Like Anderssen's Opening, 1.a3, 1.h3 is a time-wasting move, as it makes no claim on the central squares, nor does it aid development. It also leads to a slight weakening of White's kingside, albeit not as severely as Grob's Attack (1.g4) or Barnes Opening (1.f3). Since there is no need for White to make such a time-wasting first move, it is among the rarest of the 20 possible first moves. Nevertheless, IM Michael Basman has experimented with 1.h3, usually following it up with 2.g4 (transposing to the Grob), or 2.a3 followed by a quick c4, a line that has been dubbed the "Creepy Crawly". The “Creepy Crawly” is also known as the Global Opening. Black has a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Queen's Knight Defence
The Queen's Knight Defense (also known as the Nimzowitsch Queen Pawn Defence, Bogoljubov– Mikenas Defense or Lundin Defense) is a chess opening defined by the moves: :1. d4 Nc6 Unless the game transposes to another opening, the ''Encyclopedia of Chess Openings'' code for the Queen's Knight Defense is A40. Discussion This opening was tried by some hypermodern players such as Aron Nimzowitsch and Efim Bogoljubov, but it has never become very popular. The move 1...Nc6 is a fairly committal move which blocks Black's c-pawn; usually Black delays playing it until White's setup is clear. Most games featuring 1.d4 Nc6 transpose to another opening. After 2.e4 the Nimzowitsch Defense arises. After 2.Nf3 d5 a variation of the Queen's Pawn Game is possible. After 2.c4 d5 the opening is a Chigorin Defense. There are some lines which are unique to 1.d4 Nc6, most importantly 2.d5 which chases the knight away, usually to e5. The opening resembles an Alekhine's Defence but on the o ...

Englund Gambit
The Englund Gambit is a rarely played chess opening that starts with the moves: :1. d4 e5 Black's idea is to avoid the traditional queen's pawn games and create an with tactical chances, but at the cost of a pawn. The gambit is considered weak; Boris Avrukh writes that 1...e5 "seems to me the worst possible reply to White's first move". It is almost never seen in top-level play, although Paul Keres once tried it. The gambit is occasionally seen in amateur games and in correspondence chess, and the 3...Qe7 version of the gambit was frequently used by Henri Grob. Black has numerous ways to continue after 1.d4 e5 2.dxe5. Black can offer to exchange the d-pawn for White's e-pawn with 2...d6, arguing that after White captures with exd6, ...Bxd6 will offer Black a lead in to compensate for the pawn. After the continuation 2...Nc6 3.Nf3, Black may round up the e5-pawn with 3...Qe7, intending to meet 4.Bf4 with the disruptive 4...Qb4+, and ensuring that White's only way to maintai ...

English Defence
The English Defence is a chess opening characterised by the moves: :1. d4 e6 :2. c4 b6 Description White often gains a broad with 3.e4, which Black puts pressure on with moves like ...Bb7, ...Bb4, and sometimes even ...Qh4 and/or ...f5. It was developed by the Leicester player P. N. Wallis, and was taken up by several leading English players in the 1970s, such as Tony Miles, Jon Speelman and Raymond Keene. It flouts several traditional opening principles, as Black often bishops before knights and brings out the queen early. It is a somewhat unusual opening, but has been seen in high-level grandmaster play, usually as a surprise weapon, for example when Viktor Korchnoi used it to defeat Lev Polugaevsky in their world championship semifinals match at Évian 1977 (see below). Example games *Lev Polugaevsky vs. Viktor Korchnoi, Évian 1977 1.d4 e6 2.c4 b6 3.e4 Bb7 4.Qc2 Qh4 5.Nd2 Bb4 6.Bd3 f5 7.Nf3 Bxd2+ 8.Kf1 Qh5 9.Bxd2 Nf6 10.exf5 Bxf3 11.gxf3 Nc6 12.Bc3 0-0 13.Re1 ...

Queen's Pawn Game
Queen's Pawn Game broadly refers to any chess opening starting with the move 1.d4, which is the second most popular opening move after 1.e4 (King's Pawn Game). Terminology The term "Queen's Pawn Game" is usually used to describe openings beginning with 1.d4 where White does not play the Queen's Gambit. The most common Queen's Pawn Game openings are: * The London System, 2.Bf4 or 2.Nf3 and 3.Bf4 * The Trompowsky Attack, 1...Nf6 2.Bg5 and the Pseudo-Trompowsky 1...d5 2.Bg5 * The Torre Attack, 2.Nf3 and 3.Bg5 * The Stonewall Attack, 2.e3 * The Colle System, 2.Nf3 and 3.e3, * The King's Fianchetto Opening, 2.Nf3 and 3.g3 * The Barry Attack, 1...Nf6 2.Nf3 g6 3.Nc3 d5 4.Bf4 * The Richter–Veresov Attack, 1...d5 2.Nc3 Nf6 3.Bg5 or 1...Nf6 2.Nc3 d5 3.Bg5 * The Blackmar–Diemer Gambit, 1...d5 2.e4, and the Hübsch Gambit 1...Nf6 2.Nc3 d5 3.e4 In the ''Encyclopaedia of Chess Openings'' (''ECO''), Closed Games (1.d4 d5) are classified under codes D00–D69.

Hedgehog (chess)
The Hedgehog is a pawn formation in chess adopted usually by Black that can arise from several openings. Black exchanges the pawn on c5 for White's pawn on d4, and then places pawns on the squares a6, b6, d6, and e6. These pawns form a row of "spines" behind which Black their forces. Typically, the bishops are placed on b7 and e7, knights on d7 and f6, queen on c7, and rooks on c8 and e8 (or c8 and d8). Although Black's position is cramped, it has great latent energy, which may be released if Black is able to play ...b5 or ...d5 at some point. These pawn breaks are particularly effective because White usually places pawns on c4 and e4 (the Maróczy Bind). Black manoeuvring Once the basic Hedgehog structure is in place, and depending on how White responds, Black has various ways of reorganizing their pieces. The knight on d7 often hops to c5, where it attacks a white pawn on e4; or to e5, where it attacks a pawn on c4. The knight on f6 can go to e8 (when Black placed their ro ...

English Opening
The English Opening is a chess opening that begins with the move: :1. c4 A flank opening, it is the fourth most popular and, according to various databases, one of the four most successful of White's twenty possible first moves. White begins the fight for the by staking a claim to the d5-square from the wing, in hypermodern style. Although many lines of the English have a distinct character, the opening is often used as a transpositional device in much the same way as 1.Nf3 – to avoid such highly regarded responses to 1.d4 as the Nimzo-Indian and Grünfeld Defences — and is considered reliable and flexible. The English derives its name from the leading 19th century English master Howard Staunton, who played it during his 1843 match with Saint-Amant and at London 1851, the first international tournament. It did not inspire Staunton's contemporaries and caught on only in the twentieth century. It is now recognised as a opening that may be used to reach both classical ...

Réti Opening
The Réti Opening is a hypermodern chess opening whose "traditional" or "classic method" begins with the moves: :1. Nf3 d5 :2. c4 White attacks Black's pawn from the , which may occasion 2...dxc4. White may couple this plan with a kingside fianchetto (g3 and Bg2) to create pressure on the light squares in the . The opening is named after Czechoslovakian chess player Richard Réti (1889–1929). The opening is in the spirit of the hypermodernism movement that Réti championed, with the center being dominated from the wings rather than by direct occupation. If White fianchettoes both bishops, castles kingside, and refrains from occupying the center with pawns, the result may be described as the Réti system. In the ''Encyclopaedia of Chess Openings'', Réti Opening is classified as codes A04–A09, where it is closely associated with the King's Indian Attack. History According to Réti, the opening was introduced into master play in the early part of 1923. Schiller, Eric ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
King's Indian Attack
The King's Indian Attack (or KIA), also known as the Barcza System (after Gedeon Barcza) is a chess opening for White, characterized by several moves. The center pawns are developed to e4 and d3, the knights are developed to d2 and f3, the king's bishop fianchettoes at g2 following the g-pawn's movement to g3, and White castles kingside. The resulting arrangement has multiple positional themes: the pawn at d3 and the knight at d2 both defend the pawn at e4, the knight at f3 attacks the center, the fianchettoed bishop may influence the center following subsequent moves, and castling removes the king to safety while bringing a rook into the game. Unlike other chess openings, The King's Indian Attack is not a specific sequence of moves, but rather a ''system'' for White where the moves may be permuted at the player's discretion, in response to the moves of the black pieces. When a game opens with most or all of the above moves, to the exclusion of moves which typify other openin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zukertort Opening
The Zukertort Opening is a chess opening named after Johannes Zukertort that begins with the move: :1. Nf3 Sometimes the name "Réti Opening" is used for the opening move 1.Nf3, although most sources define the Réti more narrowly as the sequence 1.Nf3 d5 2.c4. A flank opening, it is the third most popular of the twenty legal opening moves White has, behind only 1.e4 and 1.d4. The move has been described by Edmar Mednis as a "perfect and flexible opening" and by others such as Aron Nimzowitsch as "certainly the most solid move, whereas moves such as 1.e4 and 1.d4 are both 'committal' and 'compromising'." The game can transpose into many other openings that usually start with 1.e4, 1.d4, or 1.c4. If Black is not careful, there is the risk of running unprepared into a highly theoretical opening, e.g. after 1.Nf3 c5 White can play 2.e4 leading to the mainline Sicilian Defense. Other common transpositions are to various lines of the Queen's Gambit Declined (after e.g. 1.N ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bird's Opening
Bird's Opening (or the Dutch Attack) is a chess opening characterised by the move: :1. f4 Bird's is a standard flank opening. White's strategic ideas involve control of the e5-square, offering good attacking chances at the expense of slightly weakening their own . Black may challenge White's plan to control e5 immediately by playing From's Gambit (1...e5); however, the From Gambit is notoriously double-edged and should only be played after significant study. The ''Encyclopaedia of Chess Openings'' assigns two codes for Bird's Opening: A02 (1.f4) and A03 (1.f4 d5). History The opening was mentioned by Luis Ramírez de Lucena in his book ''Repetición de Amores y Arte de Ajedrez con Cien Juegos de Partido'', published c. 1497. In the mid-nineteenth century the opening was sometimes played by La Bourdonnais and Elijah Williams, among others. The British master Henry Edward Bird first played it in 1855 and continued to do so for the next 40 years. In 1885, the '' Hereford Tim ...
