Dragon
The opening is named after the Draco (Latin for dragon) constellation because if you remove all the pieces and just look at black's pawn structure with the pawns on g6
and d6
it looks like the dragon constellation as shown below (image source):


Accelerated
Unlike the mainline Dragon Sicilian where d6
is a key early move (1.e4 c5 2.Nf3 d6...
), even though later it might still be pushed to d5
, the accelerated version attempts to play d7-d5
in one go, without the inclusion of an early d6
move, and hence the name accelerated Dragon.
Here's an important move order that really typifies the accelerated Dragon, where everything black has set out to do has been achieved: safe king, healthy development, a successful early d5
push to undermine white's center, powerful bishop on the long diagonal, active play in the center and on the queenside. I highly encourage you to closely study the 3 variations that can result from either of the 3 ways white can capture the pawn on d5
on the next move.

Basic plan for black:
In short, having neutralized white's central d4
pawn for our c7
pawn, black fianchettoes their kingside bishop and exerts pressure on the long diagonal from the get-go, unlike most other Sicilian variations where the dark squared bishop stands quite defensively. Additionally, the fianchetto structure is a good defensive fortress for the king.
Moreover, black's kept both central pawns (e
and d
) and in the future they can potentially make a better claim at central control as the central pawns are 2 for 1 in favour of black. Considering that white's only remaining central control lies in their e4
pawn, with constant threats of e5
kicking our knight to a less ideal post, black's constantly playing towards making the d7-d5
break happen as early as possible, neutralizing white's only central foothold.
