In chess, the Katalymov Variation (also spelled Katalimov) is a less popular line of the Sicilian Defence that begins with the moves:
The Katalymov is considered inferior since it commits Black to a plan with ...b6 rather than more aggressive Sicilian defences incorporating ...b7–b5. [1] Black must protect the b5-square, as an invasion by a white knight or bishop would be very annoying. For example, White retains a slight plus after 3.d4 cxd4 4.Nxd4 Bb7 5.Nc3 a6 6.Bd3 g6 7.f4 Bg7 8.Nf3 d6 9.0–0 Nf6 10.Qe1 0–0 11.Qh4 Nbd7 12.Bd2. [2]
The opening is a favorite of French GM Christian Bauer, with which he managed to draw a game in 2005 against currently top-ranked GM Magnus Carlsen. [3] It has also been used by top players such as Gata Kamsky, [4] Russian GM Pavel Ponkratov [5] and Soviet GM Lev Psakhis. [6]
The opening is named after Soviet IM Boris Katalymov (1932–2013). [7]
In chess, an irregular opening is an opening considered unusual or unorthodox. In the early 19th century the term was used for any opening not beginning with 1.e4 e5 or 1.d4 d5. As opening theory has developed and openings formerly considered "irregular" have become standard, the term has been used less frequently.
The Grünfeld Defence is a chess opening characterised by the moves:
The Modern Defense is a hypermodern chess opening in which Black allows White to occupy the center with pawns on d4 and e4, then proceeds to attack and undermine this "ideal" center without attempting to occupy it. The opening has been most notably used by British grandmasters Nigel Davies and Colin McNab.
The English Opening is a chess opening that begins with the move:
The Hippopotamus Defence is a chess opening system employed by Black, consisting of a double fianchetto structure and a small pawn centre. The knights are typically developed to e7 and d7 and the rook's pawns to a6 and h6. This structure can be obtained by a wide variety of move orders but it occurs most frequently via the Modern Defence or Owen's Defence. The Hippopotamus can also be played against queen's pawn openings or flank openings and is thus a genuinely universal system. The same structure is also occasionally utilized by White.
The Ware Opening, also known as Meadow Hay Opening, is an uncommon chess opening for White beginning with the move:
Anderssen's Opening is a chess opening defined by the opening move:
The Nimzowitsch-Larsen Attack is a chess opening typically starting with the move: 1.b3 but sometimes introduced by the move order 1.Nf3 and then 2.b3. The flank opening move 1.b3 prepares to fianchetto the queen's bishop where it will help control the central squares in hypermodern fashion and put pressure on Black's kingside.
The Keres Defence is a chess opening characterised by the moves:
The St. George Defence is an unorthodox chess opening for Black. The opening begins with the moves:
The Colle System, also known as the Colle–Koltanowski System, is a chess opening system for White, popularised in the 1920s by the Belgian master Edgard Colle and further developed by George Koltanowski.
Owen's Defence is an uncommon chess opening defined by the moves:
Eduard Yefimovich Gufeld was a Soviet/American International Grandmaster of chess, and a chess author.
In chess, the Cambridge Springs Defense is a variation of the Queen's Gambit Declined that begins with the moves:
The London System is an opening system in chess where White opens with 1.d4 and develops the dark-squared bishop to f4, then supports the d4-pawn with pawns on e3 and c3. The other bishop is developed to d3 and the knights typically to f3 and d2. This set-up often results in a closed game. The London System can be used against virtually any Black defence and thus comprises a smaller body of opening theory than many other openings. Although it has a reputation as a solid opening, the London System has faced criticism for its tedious nature and lack of dynamic play.
