The Accelerated Dragon (or Accelerated Fianchetto) is a chess opening variation of the Sicilian Defence that begins with the moves: :1. e4 c5 :2. Nf3 Nc6 :3. d4 cxd4 :4. Nxd4 g6 The Accelerated Dragon features an early g6 by Black. An important difference between this line and the Dragon is that Black avoids playing d7–d6, so that he can later play d7–d5 in one move, if possible. Black also avoids the Yugoslav Attack, but since White has not been forced to play Nc3 yet, 5.c4 (the Maróczy Bind) is possible. The Accelerated Dragon generally features a more positional style of play than many other variations of the Sicilian. ==Main line== One of the main lines continues: 5. Nc3 Bg7 6. Be3 Nf6 7. Bc4 (see diagram). At this point the most important Black continuations are 7...0-0 and 7...Qa5. White should not castle queenside after 7...Qa5, unlike in the Yugoslav Attack. 7... 0-0 is the main line, after which White should proceed with 8. Bb3. If Black plays 8...d6, White usually plays 9.f3 as in the Yugoslav attack. Although, Black often plays 8...a5 or 8...Qa5, after which castling queenside can be dangerous, and it is often a better idea for White to castle kingside. 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「Sicilian Defence, Accelerated Dragon」の詳細全文を読む スポンサード リンク
