Semi-Closed Game
A Semi-Closed Game (or Semi-Closed Opening) is a chess opening in which White plays 1.d4 but Black does not make the symmetrical reply 1...d5.Hooper & Whyld (1996), p. 365. ''semi-close game''. (The openings starting 1.d4 d5 are the Closed Games.) Important openings By far the most important category of the semi-closed openings are the ''Indian systems'', which begin 1.d4 Nf6. As these defenses have much in common and have a great deal more theory than all the remaining semi-closed openings put together, they are treated in a separate article; see Indian defense for details. The third most common response to 1.d4 (after 1...Nf6 and 1...d5) is 1...e6. 1...e6 rarely has independent significance, usually transposing to another opening, e.g. the Dutch Defense (2.c4 f5 or 2.Nf3 f5), French Defense (2.e4 d5), or Queen's Gambit Declined (2.c4 d5). Another possibility is 2.c4. 2...Bb4+ is the Keres Defense (also known as the Kangaroo Defense), which is fully playable, but also little ind ...

Chess Opening
The opening is the initial stage of a chess game. It usually consists of established Chess_theory#Opening_theory, theory. The other phases are the chess middlegame, middlegame and the chess endgame, endgame. Many opening sequences, known as ''openings'', have standard names such as "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 Chess theory#Opening theory, opening theory, the players are said to be "out of book". In some openings, book lines have been worked out for over 30 moves, such as some lines in the classical King's Indian Defense and in the Sicilian Defense, Najdorf Variation, Najdorf Variation of the Sicilian Defense. Professional chess players spend years studying openings, and they continue doing so throughout their careers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Modern Benoni
The Modern Benoni is a chess opening that begins with the moves 1. d4 Nf6 2. c4 c5 3. d5 e6. It is classified under the ECO codes A60–A79. After the initial moves, Black proceeds to capture on d5, creating a majority of black pawns on the queenside. To support their advance, the king's bishop is usually fianchettoed on g7. These two features differentiate Black's setup from the other Benoni defences and the King's Indian Defence, although transpositions between these openings are common. Frank Marshall invented the Modern Benoni in 1927, but his experiments with the opening went largely ignored for over 20 years. In the 1950s the system was revitalized by players in the Soviet Union, chief among them Mikhail Tal. Its subsequent adoption by players of a similarly aggressive and uncompromising style such as Bobby Fischer and Garry Kasparov established the opening's reputation as one of Black's most dynamic responses to 1.d4. The Modern Benoni suffered a serious t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chigorin Defense
The Chigorin Defense is a chess opening named for 19th-century Russian master Mikhail Chigorin. An uncommonly played defense to the Queen's Gambit, it begins with the following moves: :1. d4 d5 :2. c4 Nc6 The Chigorin Defense violates several classical principles: Black does not maintain the center pawn at d5, the c-pawn is blocked, and Black must be willing to trade a bishop for a knight. In return, Black gets quick and piece pressure on the . Although opening assessments change as improvements are found for each side, the Chigorin is generally considered for Black, and it is useful as a surprise weapon against the Queen's Gambit. Alexander Morozevich is perhaps the only modern grandmaster who regularly plays the Chigorin Defense; in the 1980s, Vasily Smyslov did employ the opening against Garry Kasparov Garry Kimovich Kasparov (born Garik Kimovich Weinstein on 13 April 1963) is a Russian Grandmaster (chess), chess grandmaster, former World Chess Champion (1985 ...

Nimzowitsch Defense
The Nimzowitsch Defence (named after Aron Nimzowitsch) is a somewhat uncommon chess opening characterised by the moves: :1. e4 Nc6 This opening is an example of a hypermodern opening in which Black invites White to occupy the of the board at an early stage with pawns. Black's intent is to block or otherwise restrain White's central pawns and, if allowed to do so by inaccurate play by White, eventually undermine the White pawn centre by well-timed pawn advances of their own or by attacking the white pieces defending the centre. World Champion Garry Kasparov and Grandmaster Raymond Keene wrote that it "has never been fully accepted as a dependable opening. Nevertheless it is sound and offers the maverick spirit a great deal of foreign territory to explore." The Nimzowitsch is included under code B00 in the ''Encyclopaedia of Chess Openings''. Main line: 2.d4 White takes the initiative in the centre. Black's main continuations are 2...d5 or 2...e5. 2...d5 The line that A ...

Queen's Knight Defense
The Queen's Knight Defense (also known as the Nimzowitsch Queen Pawn Defense, 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 other openings. 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 that 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 oppos ...

Polish Defense
The Polish Defense is the name commonly given to one of several sequences of chess opening moves characterized by an early ...b5 by Black. The name "Polish Defense" is given by analogy to the Polish Opening, 1.b4. The original line was : 1. d4 b5 as played by Alexander Wagner, a Polish player and openings analyst, against Kuhn in the 1913 Swiss Correspondence Championship. Wagner published an analysis of the opening in ''Deutsches Wochenschach'' in 1914, when he was living in Stanislau, Galicia, Austria-Hungary (now Ivano-Frankivsk, Ukraine). Later the name was also applied to :1. d4 Nf6 :2. Nf3 b5 and other lines in which Black plays an early ...b7-b5, which are sometimes called the Polish Defense Deferred. Details With ...b5, Black tries to take control of c4, but 1.d4 b5 is generally considered dubious after 2.e4, threatening 3.Bxb5.

Wade Defense
The Wade Defence is a chess opening characterised by the initial moves: : 1. d4 d6 : 2. Nf3 Bg4 The position can also arise from the move order 1.Nf3 d6 2.d4 Bg4. History The opening is named after British IM Bob Wade (1921–2008), originally from New Zealand, who played it for over 30 years. A number of grandmasters have often played the opening, including Julian Hodgson, Michael Adams, Vlastimil Jansa, and Tony Miles. Jouni Yrjölä and Jussi Tella, in their book ''An Explosive Chess Opening Repertoire for Black'', state that the opening: ..was played in 1938 by Rudolf Spielmann and used in the 1960s by Stein and Kavalek among others ... But the towering figure of the line is Julian Hodgson, who popularized it with many dynamic performances. Among the other practitioners, the contributions of Miles, Adams, Hickl and Jansa to the theoretical development of the line are worth mentioning. In recognition of Hodgson's contributions, the authors refer to the openi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Philidor's 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 ...

Pirc Defense
The Pirc Defence ( ) is a chess opening characterised by the response of Black to 1.e4 with 1...d6 and 2...Nf6, followed by ...g6 and ...Bg7, while allowing White to establish a with pawns on d4 and e4. It is named after the Slovenian grandmaster Vasja Pirc. The Pirc Defence is usually defined by the opening sequence :1. e4 d6 :2. d4 Nf6 :3. Nc3 g6 This is the most commonly played line after Black responds to 1.e4 with 1...d6. It has been claimed to give rise to somewhat interesting and exciting games, where Black will have but has to be cautious about playing too passively. According to Garry Kasparov, the Pirc Defence is "hardly worth using in the tournaments of the highest category", as it gives White "too many opportunities for anybody's liking". Description The Pirc Defence, named after Slovenian grandmaster Vasja Pirc, is a relatively new opening; while it was seen on occasion in the late nineteenth century, it was considered irregular, thus remaining a side ...
