An Open Game (or Double King's Pawn Opening) is a generic term for a family of chess openings beginning with the 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. When written in lowercase, the term "open game" refers to a chess position where , and are open, and tending to more Chess tactic, tactical gameplay. It is possible that an Open Game may lead to a . 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 , 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 is "Best by test." On the negative side, 1.e4 places a pawn (chess), pawn on an undefended square and w ...

King's Pawn Game
The King's Pawn Game is any chess opening starting with the move: : 1. b:Chess Opening Theory/1. e4, e4 It is the most popular opening move in chess, followed by 1.d4, the Queen's Pawn Game. Principles White opens with the most popular of the twenty possible opening moves. Since nearly all openings beginning 1.e4 have names of their own, the term ''King's Pawn Game,'' unlike Queen's Pawn Game, is rarely used to describe the opening of the game. Advancing the king's pawn two squares is highly useful because it occupies a square, attacks the center square d5, and allows the of White's and queen (chess), queen. Bobby Fischer said that the King's Pawn Game is "Best by test", and proclaimed that "With 1.e4! I win." Opening categorization and continuations King's Pawn Games are further classified by whether Black responds with b:Chess Opening Theory/1. e4/1...e5, 1...e5 or not.

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 Four Knights usually leads to quiet , though there are also some variations. The opening is fairly popular with beginners who strictly adhere to the opening principle: "Develop knights before bishops." One of its practical advantages is that it can be played in response to the Petrov's Defense: after 1. e4 e5 2. Nf3 Nf6 3. Nc3, Black's best move is 3...Nc6. The Four Knights 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 several 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 fro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bishop's Opening
The Bishop's Opening is a chess opening that begins with the moves: :1. e4 e5 :2. Bc4 White attacks Black's f7-square and prevents Black from advancing the d-pawn to d5. By ignoring the beginner's maxim "develop knights before bishops", White leaves their f-pawn unblocked, preserving the possibility of f2–f4. The f2–f4 gives the Bishop's Opening an affinity with the King's Gambit and the Vienna Game, two openings that share this characteristic. The Bishop's Opening can transpose into either of these openings, and in particular a favorable variation of the King's Gambit, but with care Black can circumvent this. Transpositions into the Giuoco Piano and the Two Knights Defense and other openings are also possible. The ''Encyclopaedia of Chess Openings'' assigns the Bishop's Opening the codes C23 and C24. History and use The Bishop's Opening is one of the oldest openings to be analyzed; it was studied by Lucena and Ruy Lopez. Later it was played by Philidor, whose ...

Vienna Game
The Vienna Game is an opening in chess that begins with the moves: :1. e4 e5 :2. Nc3 White's second move is less common than 2.Nf3, and is also more recent. The original idea behind the Vienna Game was to play a delayed King's Gambit with f4 (the Vienna Gambit), but in modern play White often plays more (for example, by fianchettoing their king's bishop with g3 and Bg2). Black most often continues with 2...Nf6. The opening can also lead to the Frankenstein–Dracula Variation. Weaver W. Adams famously claimed that the Vienna Game led to a for White. Nick de Firmian concludes in the 15th edition of ''Modern Chess Openings'', however, that the opening leads to with by both sides. Falkbeer Variation: 2...Nf6 After 2...Nf6, the Falkbeer Variation, White has three main options: 3.f4, 3.Bc4, and 3.g3. Note that 3.Nf3 transposes to the Petrov's Three Knights Game, which after 3...Nc6 leads to the Four Knights Game. 3.f4 At grandmaster level, the gambit move 3.f4 is ...

King's Gambit
The King's Gambit is a chess opening that begins with the moves: :1. e4 e5 :2. f4 White offers a pawn to divert the black e-pawn. If Black accepts the gambit, White may play d4 and Bxf4, regaining the gambit pawn with domination, or direct their forces against the weak square f7 with moves such as Nf3, Bc4, 0-0, and g3. A downside to the King's Gambit is that it weakens White's king's position, exposing it to the latent threat of ...Qh4+ (or ), which may force White to give up castling rights. The King's Gambit is one of the oldest documented openings, appearing in the earliest of chess books, Luis Ramírez de Lucena's ''Repetición de Amores y Arte de Ajedrez'' (1497). It was examined by the 17th-century Italian chess player Giulio Cesare Polerio. The King's Gambit was one of the most popular openings until the late 19th century, when improvements in defensive technique led to its decline in popularity. It is infrequently seen at master level today, as Black has severa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Damiano Defense
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 prevents the g8-knight from developing to f6 and weakens Black's . 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 their kingside and prevents Black from developing their knight to f6. 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! The most forceful move is the knight sacrifice 3.Nxe5 Taking the knight with 3...fxe5? exposes Black to a deadly attack after 4.Qh5+ Ke ...

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 16th century by Giulio Cesare Polerio and then 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 mo ...

Elephant Gambit
The Elephant Gambit (also called the Queen's Pawn Countergambit, Englund Counterattack or Turkish Gambit) is a rarely played chess opening beginning with the moves: :1. e4 e5 :2. Nf3 d5 The Elephant Gambit is generally considered unsound, with black typically unable to gain compensation for the sacrificed pawn. 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 ...

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, Washingto ...

Philidor Defense
The Philidor Defence (or Philidor's Defence) is a chess opening characterised by the moves: :1. e4 e5 :2. Nf3 d6 The opening is named after the famous 18th-century player François-André Danican Philidor, who advocated it as an alternative to the common 2...Nc6. His original idea was to challenge White's by the pawn thrust ...f7–f5. Today, the Philidor is known as a but passive choice for Black, and is seldom seen in top-level play except as an alternative to the heavily analysed openings that can ensue after the normal 2...Nc6. It is considered a good opening for amateur players who seek a defensive strategy that is simpler and easier to understand than the complex positions that result from an opening such as the French Defence. The ''Encyclopaedia of Chess Openings'' code for Philidor Defence is C41. History In his 1561 book, Ruy Lopez, seeking to debunk Pedro Damiano, advocated 2...d6 as superior to 2...Nc6, on the grounds that 2...Nc6 allows the strong move 3 ...

Petrov's Defence
Petrov's Defence or the Petrov Defence (also called Petroff Defence, Petrov's Game, Russian Defence, or Russian Game ">/nowiki> is a chess opening characterised by the following moves: :1. e4 e5 :2. Nf3 Nf6 Though this response has a long history, it was first popularised by Alexander Petrov, a Russian chess player in the mid-19th century. In recognition of the early investigations by the Russian masters Petrov and Carl Jaenisch, this opening is called the Russian Game in some countries. The Petrov has a drawish reputation; however, it offers attacking opportunities for both sides, and a few lines are quite . Often a trade occurs and Black, after gaining a tempo, has a well-placed knight. Pillsbury's game in 1895 against Emanuel Lasker testifies to this. The Black counterattack in the also avoids the Ruy Lopez, Giuoco Piano (and other lines of the Italian Game), and the Scotch Game. The Petrov has been adopted by many of the world's leading players, including world cha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inverted Hungarian Opening
The Inverted Hungarian Opening or Tayler Opening is an uncommon chess opening that starts with the moves: :1. e4 e5 :2. Nf3 Nc6 :3. Be2 It is so-named because the position of White's bishop on e2 resembles that of Black's bishop on e7 in the Hungarian Defense. "This opening is also known as the Inverted Hanham and was played most prominently by Tartakower against Bogoljubow at London 1922." Description The Inverted Hungarian is even rarer than the already very uncommon Hungarian Defense, although it is perfectly for White. It may appeal to White players who wish to avoid extensively analyzed double king pawn openings such as the Ruy Lopez, and to those who favor defensive positional maneuvering battles as also often result from the Hungarian Defense. With the advantage of the first move, White has greater latitude to play moves that are not objectively the strongest without incurring disadvantage. Since White's third move 3.Be2 makes no threats, there are many satisfac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
