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 themselves. The opening has been most notably used by British grandmasters Nigel Davies and Colin McNab. The Modern Defense is closely related to the Pirc Defence, the primary difference being that in the Modern, Black delays developing his knight to f6. (The delay of ...Nf6 attacking White's pawn on e4 gives White the option of blunting the g7-bishop with c2–c3.) Transpositional possibilities between the two openings are rife. 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". ==Main lines== A typical move order for the Modern Defense is 1. e4 g6 2. d4 Bg7, with main lines: * 3. Nc3 d6 4. f4 c6 5. Nf3 Bg4 (ECO code B06); * 3. c4 (ECO code A40) d6 4. Nc3 Nc6 5. Be3 e5 6. d5 Ne7 (7.g4 will be answered by 7...f5 8.gxf5 gxf5 9.Qh5+ Ng6 10.exf5 Qh4 11.Qxh4 Nxh4 12.Nb5 Kd8). 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Modern Defense」の詳細全文を読む スポンサード リンク
