Open Games
An Open Game (or Double King's Pawn Opening) is a chess opening that begins with the following moves: :1. e4 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 and king's 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 on an undefended square and weakens the squares d4 and f4. If Black keeps the symmetry by replying 1...e5, the result is an Open Game . Variations The most popular seco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
King's Pawn Game
The King's Pawn Game is any chess opening starting with the move: :1. e4 It is the most popular opening move in chess, followed by the Queen's Pawn Game. Details about the move and the game plan White opens with the most popular of the twenty possible opening moves. Although effective in winning for White (54.25%), it is not quite as successful as the four next most common openings for White: 1.d4 (55.95%), 1.Nf3 (55.8%), 1.c4 (56.3%), and 1.g3 (55.8%). 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 grandmaster 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 cl ...

Petrov's Defence
Petrov's Defence or the Petrov Defence (also called Petroff Defence, Petrov's Game, Russian Defence, or Russian Game – russian: Русская партия) 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 centre 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 lea ...

Danish Gambit
The Danish Gambit, known as the ' in German and the ' in Dutch (both meaning Nordic Gambit), is a chess opening that begins with the moves: :1. e4 e5 :2. d4 exd4 :3. c3 White will sacrifice one or two pawns for the sake of rapid and the attack. However, with care, Black can accept one or both pawns safely, or simply decline the gambit altogether with good chances. Although it may have been known earlier, Danish player Martin Severin From essayed the gambit in the Paris 1867 tournament and he is usually given credit for the opening. The Danish Gambit was popular with masters of the attack including Alekhine, Marshall, Blackburne, and Mieses, but as more defensive lines for Black were discovered and improved, it lost favor in the 1920s. Today it is rarely played in top-level chess. History From the very beginning the nomenclature of the Danish Gambit was very confusing. The idea stems from a famous correspondence game London–Edinburgh, 1824: 1.e4 e5 2.Nf3 Nc6 3.d4 e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sacrifice (chess)
In chess, a sacrifice is a move that gives up a piece with the objective of gaining tactical or positional compensation in other forms. A sacrifice could also be a deliberate exchange of a chess piece of higher value for an opponent's piece of lower value. Any chess piece except the king may be sacrificed. Because players usually try to hold on to their own pieces, offering a sacrifice can come as an unpleasant surprise to one's opponent, putting them off balance and causing them to waste precious time trying to calculate whether the sacrifice is sound or not, and whether to accept it. Sacrificing one's queen (the most valuable piece), or a string of pieces, adds to the surprise, and such games can be awarded . Types of sacrifice Real versus sham Rudolf Spielmann proposed a division between sham and real sacrifices: * In a ''real sacrifice'', the sacrificing player will often have to play on with less than their opponent for quite some time. * In a ''sham sacrifice'', t ...

Center Game
The Center Game is a chess opening that begins with the moves: :1. e4 e5 :2. d4 exd4 The game usually continues 3.Qxd4 Nc6, with a gain of tempo for Black due to the attack on the white queen. (Note that 3.c3 is considered a separate opening: the Danish Gambit.) General concepts White's 2nd move challenges the center by attacking the e-pawn and also opening up the d- for the rook and queen to attack, but at the cost of moving the queen early and allowing Black to develop with a tempo with 3...Nc6. In White's favor, after 4.Qe3, the most commonly played retreat, the position of the white queen hinders Black's ability to play ...d5. The is cleared of pieces quickly which facilitates castling and may allow White to quickly develop an attack. From e3, the white queen may later move to g3 where she will pressure Black's g7-square. History The Center Game is an old opening. It was mostly abandoned by 1900 because no advantage could be demonstrated for White. Jacques Mie ...

Transposition (chess)
In chess, a transposition is a sequence of moves that results in a position which may also be reached by another, more common sequence of moves. Transpositions are particularly common in the opening, where a given position may be reached by different sequences of moves. Players sometimes use transpositions deliberately, to avoid variations they dislike, lure opponents into unfamiliar or uncomfortable territory or simply to worry opponents. See review at In chess the verb "transpose" means to shift the game onto a different opening track from which it started. Transposition tables are an essential part of a computer chess program. Transpositions exist in other abstract strategy games such as shogi, Go, tic-tac-toe and Hex. Examples Positions reached by different routes For instance, the first position can be obtained from the Queen's Gambit: :1. d4 d5 :2. c4 e6 :3. Nc3 Nf6 But this position can also be reached from the English Opening: :1. c4 e6 :2. Nc3 Nf6 :3. d4 d5 so ... [...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 its 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. Larsen was one ...

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 his 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 forced win 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 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 considered too risky an opening. ...

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 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 ...
