Van 't Kruijs Opening
The Van 't Kruijs Opening () is a chess opening defined by the move: : 1. e3 It is named after the Dutch player Maarten van 't Kruijs (1813–1885) who won the sixth Dutch championship in 1878. As this opening move is rarely played, it is considered an irregular opening, and thus it is classified under the A00 code in the ''Encyclopaedia of Chess Openings''. Discussion Although there are several examples from games in the 19th century, the Van 't Kruijs Opening is not popular in the modern era and is not a common choice for grandmasters, but its ability to transpose into many different openings explains its attraction for some players such as Pavel Blatny, Aron Nimzowitsch, and Bent Larsen. Benjamin & Schiller (1987) call it a "chameleon". According to ChessBase, it ranks sixth in popularity out of the twenty possible first moves. The loss of popularity is due to 1.e3 gaining little except as a transposition strategy to reach other positions. It releases the , and m ...

Maarten Van 't Kruijs
Maarten van 't Kruijs (; 18 February 1813 – 30 March 1885) was a Dutch chess player and organist. In the international chess world, Van 't Kruijs is primarily known for being the namesake of the Van 't Kruijs Opening, 1.e3. Living in a time before the World Chess Championship, he was considered the strongest chess player in the Netherlands, and he was considered one of the strongest in the world at the time by his contemporaries, including Adolf Anderssen. He was a well-developed player who won various Dutch chess championships between 1851 and 1878. Despite such high praise, little is known of Van 't Kruijs due to his timidity and overt life of privacy. Early life Little is known of the early life of Van 't Kruijs. It can be established, however, that he was born in Uithoorn on 18 February 1813. It is generally believed that he was a well-to-do Dutch man who learned chess sometime as a child. However, there are very few sources that reveal biographical details about Van 't ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transposition (chess)
In chess, a transposition is a sequence of moves that results in a position that 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 To transpose is to play a move that results in a transposition. 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 the English Opening has transposed into the ...

List Of Chess Openings Named After People
''The Oxford Companion to Chess'' lists 1,327 named openings and variants. Chess players' names are the most common sources of opening names. The name given to an opening is not always that of the first player to adopt it; often an opening is named for the player who was one of the first to popularise it or to publish analysis of it.

List Of Chess Openings
This is a list of chess openings, organised by the ''Encyclopaedia of Chess Openings'' (''ECO'') code classification system. The chess openings are categorised into five broad areas ("A" through "E"), with each of those broken up into one hundred subcategories ("00" through "99"). The openings were published in five volumes of ''ECO'', with volumes labeled "A" through "E".

From's Gambit
Bird's Opening (or the Dutch Attack) is a chess opening characterised by the move: : 1. f4 Named after 19th century English player Henry Bird, Bird's opening 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 t ...

Open Game
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 ...

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 r ...

Stonewall Attack
The Stonewall Attack is a chess opening characterized by White playing pawns to d4 and e3, bishop to d3, knight to d2, and then completing the Stonewall structure by playing pawns to c3 and f4. This set-up is usually achieved by a 1.d4 move order but transposition is also possible via Bird's Opening, 1.f4. The Stonewall Attack is a ''system''; White heads for a very specific pawn formation, rather than trying to memorize long lines of different variations. Black can set up in various ways in response, but ''MCO-15'' gives the following as a main line: 1.d4 d5 2.e3 Nf6 3.Bd3 c5 4.c3 Nc6 5.f4. History The earliest recorded game to feature the Stonewall Attack would appear to have been Howard Staunton vs John Cochrane, London, 1842. The first player to use the opening regularly, however, was the Boston master Preston Ware, who frequently opened 1.d4 2.f4 from 1876 to 1882. Employing this unusual move order Ware was often able to reach Stonewall type positions (although later play ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dutch Defence
The Dutch Defence is a chess opening characterised by the moves: : 1. d4 f5 Black's 1...f5 stakes a claim to the e4-square and envisions an attack in the middlegame on White's ; however, it also weakens Black's kingside to some extent, especially on the e8–h5 diagonal. Like its 1.e4 counterpart, the Sicilian Defence, the Dutch is an aggressive and unbalancing opening, resulting in the lowest percentage of draws among the most common replies to 1.d4. Historically, White has tried many methods to exploit the kingside weaknesses, such as the Staunton Gambit (2.e4) and Korchnoi Attack (2.h3 and 3.g4). The Dutch has never been a main line against 1.d4 and is rarely seen today in high-level competition, although a number of top players, including Alexander Alekhine, Bent Larsen, Paul Morphy, Miguel Najdorf, Simon Williams, and Hikaru Nakamura have used it with success. Its most notable use may have been in 1951, when both World Champion Mikhail Botvinnik and his challen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
French Defence
The French Defence is a chess opening characterised by the moves: :1. e4 e6 This is most commonly followed by 2.d4 d5. Black usually plays ...c5 soon after, attacking White's and gaining on the . The French has a reputation for solidity and resilience, although some lines such as the Winawer Variation can lead to complications. Black's position is often somewhat in the early game; in particular, the pawn on e6 can impede the of the bishop on c8, known by many players as the French bishop. Basics Following the opening moves 1.e4 e6, the main line of the French Defence continues 2.d4 d5 (see below for alternatives). White sets up a , which Black immediately challenges by attacking the pawn on e4. The same position can be reached by transposition from a Queen's Pawn Game after 1.d4 e6 2.e4 d5 or the declining of a Blackmar–Diemer Gambit after 1.d4 d5 2.e4 e6. White's options include defending the e4-pawn with 3.Nc3 or 3.Nd2, advancing it with 3.e5, or exchangin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Queen's Pawn Game
The Queen's Pawn Game is any chess opening starting with the move: : 1. d4 It 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.
