Modern chess openings knight pawn defense
Following 2.Nc3, Black can transpose to a closed Sicilian with 2.c5 or play 2.Bg7. Transpositions are possible after 2.c4, for example a Maróczy Bind results after 2.c5 3.Nf3 Bg7 (or Nc6) 4.d4 cxd4 5.Nxd4 and the Averbakh system is reached after 2.Bg7 3.d4 d6 4.Nc3.Īfter 2.Nf3, Black can play 2.c5, transposing to the Sicilian Defense, or 2.Bg7. On 4.Be2, Black can retreat the knight or gambit a pawn with 4.d6!? If White plays 3.Nc3 instead of 3.e5, Black can transpose to the Pirc Defence with 3.d6 or continue in unconventional fashion with 3.d5!?) (If White plays 4.g4, Black retreats the knight with 4.Ng7. Another is the Norwegian Defence (also known as the North Sea Defence) which begins 1.e4 g6 2.d4 Nf6 3.e5 Nh5. The Hippopotamus Defence is one such system. Other unusual openings can be reached after 1.e4 g6. (A more refined version is the Monkey's Bum Deferred, where White plays Bc4 and Qf3 only after developing the queen's knight.) The flexibility and toughness of the Modern Defense has provoked some very aggressive responses by White, including the crudely named Monkey's Bum, a typical sequence being 1.e4 g6 2.Bc4 Bg7 3.Qf3.
The tenth edition of Modern Chess Openings (1965) grouped the Pirc and Robatsch together as the "Pirc–Robatsch Defense".
#Modern chess openings knight pawn defense code#
The Encyclopaedia of Chess Openings ( ECO) classifies the Modern Defense as code B06, while codes B07 to B09 are assigned to the Pirc. There are numerous transpositional possibilities between the two openings. Nf6 attacking White's pawn on e4 gives White the option of blunting the g7-bishop with c2–c3. The Modern Defense is closely related to the Pirc Defence, the primary difference being that in the Modern, Black delays developing the knight to f6. The opening has been most notably used by British grandmasters Nigel Davies and Colin McNab. The Modern Defense (also known as the Robatsch Defence after Karl Robatsch) 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 themself.
