King's Knight Opening
The King's Knight Opening is a chess opening consisting of the moves: :1. e4 e5 :2. Nf3 White's second move attacks the e-pawn. Black usually defends this with 2...Nc6, which leads to several named openings. Of the alternatives, the most important are Petrov's Defense (2...Nf6) and Philidor's Defense (2...d6). Main line: 2...Nc6 Most games (more than 80%) continue with 2...Nc6. Some moves from here include: * 3. Bb5: Ruy Lopez ** 3...a6: Ruy Lopez, Morphy Defence (main line) ** 3...Nf6: Ruy Lopez, Berlin Defence ** 3...d6: Ruy Lopez, Steinitz Defence ** 3...f5: Ruy Lopez, Schliemann Defence ** 3...Bc5: Ruy Lopez, Classical Defence * 3.

Open Game
An Open Game (or Double King's Pawn Opening) is a chess opening that begins with the following moves: :1. b:Chess Opening Theory/1. e4, e4 b:Chess Opening Theory/1. e4/1...e5, e5 White has moved the king's pawn two squares and Black has replied in kind. The result is an Open Game. Other responses to 1.e4 are termed Semi-Open Games or Single King's Pawn Games. It should not be confused with the term "" (lowercase o and g), referring to a chess position where ranks, files and diagonals are open, and tending to more tactical gameplay. Analysis White opens by playing 1.e4, which is the most popular opening move and has many strengths—it immediately stakes a claim in the center, and frees two pieces (the queen (chess), queen and king's bishop (chess), bishop) for action. The oldest openings in chess follow 1.e4. Bobby Fischer wrote that 1.e4 was "Best by test." On the negative side, 1.e4 places a pawn (chess), pawn on an undefended square and weakens the squares d4 and f4. If Black ...

Three Knights Game
The Three Knights Game is a chess opening which most commonly begins with the moves: :1. e4 e5 :2. Nf3 Nc6 :3. Nc3 In the Three Knights Game, Black chooses to break symmetry in order to avoid the main lines of what is often considered the drawish Four Knights Game after the usual 3...Nf6. The relevant '' ECO'' code is C46. Black's third move After tries such as 3...d6 or 3...Be7, White can play 4.d4, leaving Black with a cramped position resembling Philidor's Defense. If Black plays 3...Bc5 instead, White can eliminate Black's outpost at e5: 4.Nxe5 Nxe5 5.d4 Bd6 6.dxe5 Bxe5. Since tournament praxis shows the line seems to favor White, Black usually plays 3...Bb4 or 3...g6. Continuations then are typically 3...Bb4 4.Nd5 and 3...g6 4.d4 exd4 5.Nd5. Another alternative for Black is 3...f5!? – the Winawer Defense (or Gothic Defense). Then 4.Bb5 transposes into the Schliemann variation of the Ruy Lopez with 4.Nc3. The Three Knights is almost never seen at master level ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Damiano Defence
The Damiano Defence is a chess opening beginning with the moves: # e4 e5 # Nf3 f6? The defence is one of the oldest chess openings, with games dating back to the 16th century. It is a weak opening that gives a large advantage for White after 3.Nxe5. Even if White does not go for this continuation, simple leads to an advantage since 2...f6 weakened Black's as well as took away the best square for the g8-knight. The '' ECO'' code for the Damiano Defence is C40 (King's Knight Opening). 3.d4 and 3.Bc4 Black's 2...f6 is a weak move that exposes Black's king, weakens Black's kingside and takes away his knight's best square. The moves 3.d4 and 3.Bc4 are strong replies; I.A. Horowitz wrote (substituting algebraic notation for his descriptive notation), "Simple and potent is 3.Bc4 d6 4.d4 Nc6 5.c3, after which Black chokes to death." 3.Nxe5! Most forceful, however, is the knight sacrifice 3.Nxe5 Taking the knight with 3...fxe5? exposes Black to a deadly attack after 4.Qh5+ Ke7 (4 ...

Gunderam Defense
The Gunderam Defense, also known as the Brazilian Defense or the Câmara Defense if followed by moves ...g6, ...Bg7 and ...Nf6, creating the typical King's Indian formation, is a rarely played chess opening starting with the moves: :1. e4 e5 :2. Nf3 Qe7 It is named after chess player and theoretician , though Hélder Câmara played it 4 years prior to Gunderam. History The opening was first played by International Master Hélder Câmara in 1954, in the IV Centennial of the City of São Paulo Tournament and the XXII Brazilian Chess Championship. Gunderam played it for the first time in a correspondence match against August Babel in 1958 and published an analysis of it in his book ''Neue Eröffnungswege'', in 1961. He named this defense "''Damenverteidigung''" ("Queen Defence"), whose main line would be 1. e4 e5 2.Nf3 Qe7 3.Nc3 c6 4.Bc4 f5. He also analyzed a sharp line characterized by the moves: 1.e4 e5 2.Nf3 Qe7 3.Bc4 f5 4.exf5 d5 5.Bxd5 Nf6 6.Bb3 Bxf5. In 1969, Washington ...

Elephant Gambit
The Elephant Gambit (also called the Queen's Pawn Countergambit or Englund Counterattack) is a rarely played chess opening beginning with the moves: :1. e4 e5 :2. Nf3 d5 Although the Elephant Gambit is considered unsound, it has been used frequently by the Barbadian master Philip Corbin. Lines White is able to capture either of Black's center pawns with the advantage, either by 3.exd5 or 3.Nxe5. With a center pawn removed, Black is in a passive position with White clearly having the initiative as White controls more . 3.exd5 Black's responses to 3.exd5 include 3...e4 and 3...Bd6 (the Elephant Gambit proper). 3...Qxd5 saves the pawn, but leaves White with a big lead in after 4.Nc3. 3...e4 After 3...e4 4.Qe2 Nf6 lines might continue: * 5.d3 Qxd5 6.Nbd2 Be7 7.dxe4 Qe6 and White remains a pawn ahead, although Black's development is somewhat smoother. * 5.d3 Be7 6.dxe4 0-0 7.Nc3 Re8 8.Bd2 Bb4 9.0-0-0, with advantage for White (Nick de Firmian). * 5.Nc3 Be7 6.Nxe4: ** 6...Nxd ...

Latvian Gambit
The Latvian Gambit (or Greco Countergambit) is a chess opening characterised by the moves: :1. e4 e5 :2. Nf3 f5 It is one of the oldest chess openings, having been analysed in the 17th century by Gioachino Greco, after whom it is sometimes named. The opening has the appearance of a King's Gambit with . It is an aggressive but objectively dubious opening for Black which often leads to wild and tricky positions.Nick de Firmian, ''Modern Chess Openings, 15th edition'', Random House Puzzles & Games, 2008, p. 144. . FIDE Master Dennis Monokroussos even goes so far as to describe it as "possibly the worst opening in chess". While Paul van der Sterren observes: The Latvian is, and has always been, uncommon in top-level play, but some correspondence players are devotees. The '' ECO'' code for the Latvian Gambit is C40 (King's Knight Opening). History The opening was originally known as the Greco Countergambit, and some modern writers still refer to it as such.

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] |
Ponziani Opening
The Ponziani Opening is a chess opening that begins with the moves: :1. e4 e5 :2. Nf3 Nc6 :3. c3 It is one of the oldest chess openings, having been discussed in the literature by 1497. It was advocated by Howard Staunton, generally considered the world's strongest player from 1843 to 1851, in his 1847 book ''The Chess-Player's Handbook''. For some decades, it was often called "Staunton's Opening" or the "English Knight's Game" as a result. Today, it is usually known by the name of Domenico Lorenzo Ponziani, whose main contribution to the opening was his introduction, in 1769, of the 3...f5 The opening is now considered inferior to 3.Bb5, the Ruy Lopez, and 3.Bc4, the Italian Game, and is accordingly rarely seen today at any level of play. Black's main responses are 3...Nf6, leading to play, and 3...d5, leading to play. Ponziani's countergambit 3...f5!? was successfully played in the grandmaster game Hikaru Nakamura–Julio Becerra Rivero, US Championship 2007. Magnus Ca ...

Four Knights Game
The Four Knights Game is a chess opening that begins with the moves: :1. e4 e5 :2. Nf3 Nc6 :3. Nc3 Nf6 This is the most common sequence, but the knights may in any order to reach the same position. The opening is fairly popular with beginners who strictly adhere to the opening principle: "Develop knights before bishops." It was one of the workhorses in the family of the Open Game, at even the highest levels, until World War I. Thereafter it fell by the wayside, along with a number of other Open Games. In this period ambitious players explored the Ruy Lopez, believing it a better attempt by White to exploit the advantage of the first move. In the 1990s, this opening saw a renaissance, and is now seen in the praxis of players from beginner to grandmaster. The Four Knights usually leads to quiet , though there are some variations. The ''Encyclopaedia of Chess Openings'' has three codes for the Four Knights Game: * C49: 4.Bb5 Bb4 (Symmetrical Variation) * C48: 4.Bb5 without ...

Scotch Game
The Scotch Game, or Scotch Opening, is a chess opening that begins with the moves: :1. e4 e5 :2. Nf3 Nc6 :3. d4 Ercole del Rio, in his 1750 treatise ''Sopra il giuoco degli Scacchi, Osservazioni pratiche d’anonimo Autore Modenese'' ("On the game of Chess, practical Observations by an anonymous Modenese Author"), was the first author to mention what is now called the Scotch Game. The opening received its name from a correspondence match in 1824 between Edinburgh and London. Popular in the 19th century, by 1900 the Scotch had lost favour among top players because it was thought to release the central tension too early and allow Black to without difficulty. More recently, grandmasters Garry Kasparov and Jan Timman helped to repopularise the Scotch when they used it as a surprise weapon to avoid the well-analysed Ruy Lopez. Analysis White aims to dominate the by exchanging their d-pawn for Black's e-pawn. Black usually plays 3...exd4, as they have no good way of mainta ...

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] |
