Sicilian Defence, Accelerated Dragon
chess opening, variation of the Sicilian Defence
The Accelerated Dragon (or Accelerated Fianchetto) is a variation of the Sicilian Defence that begins with the moves:
1. e4 c5
2. Nf3 Nc6
3. d4 cxd4
4. Nxd4 g6
The opening features an early ...g6 by Black. An important difference between this line and the Dragon is that Black avoids playing ...d7–d6 so that ...d7–d5 can be played later in one move, if possible. Black also avoids the Yugoslav Attack, but since White has not yet played Nc3, 5.c4 (the Maróczy Bind) is possible.
The Accelerated Dragon generally features a more positional style of play than in many other lines of the Sicilian.
Alternative move order
The Accelerated Dragon can also be achieved through the following move order: 1.e4 c5 2.Nf3 g6 3.d4 cxd4 4.Nxd4 Nc6. After 2...g6, the opening is classified as the Hyperaccelerated Dragon.

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it.
