Modern Defense
The Modern Defense (also known as the Robatsch Defense) is a hypermodern chess opening which usually starts with the opening moves:
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 Modern Defense is closely related to the Pirc Defense, the primary difference being that in the Modern, Black delays developing the knight to f6. This delay of attacking White's pawn on e4 gives White the option of blunting the g7-bishop with c2–c3. There are numerous transpositional possibilities between the two openings.
The Encyclopaedia of Chess Openings (ECO) classifies the Modern Defense as code B06, while codes B07 to B09 are assigned to the Pirc. The tenth edition of Modern Chess Openings (1965) grouped the Pirc and Robatsch together as the "Pirc–Robatsch Defense". The opening has been most notably used by British grandmasters Nigel Davies and Colin McNab.
White's strongest response to the Modern Defense is 2.d4, to which Black typically responds 2...Bg7. The main continuations are:
Other possibilities include:
Bobby Fischer suggested the move 3.h4!? as an unorthodox try against 1...g6 2.d4 Bg7, in his annotation to a game against Pal Benko. (Fischer played 3.Nc3 in the actual game.) The idea is to pry open Black's kingside by h4–h5 followed by hxg6, as ...gxh5 would greatly weaken the cover to Black's king.
The Modern Defense, Averbakh System (ECO A42) can be reached by the lines:
Possible moves for Black at this point include 4...Nf6, 4...Nc6, 4...e5, and 4...Nd7. The move 4...Nf6 leads to a position of the King's Indian Defense, where White has options 5.Nf3, 5.f3, 5.Be2, 5.f4, and so on.
