Sicilian Defence, Dragon Variation: Accelerated Dragon
Skipping ...d6 saves a tempo — the g7 bishop arrives with maximum speed.
Sicilian Defence, Dragon Variation: Accelerated Dragon is one of the most compelling entries in the Encyclopaedia of Chess Openings — and a line that repays every hour you sink into it.
After 6…d6 the position resolves into a fluid centre — one side has staked a central pawn the other must decide how to challenge, so the structure is still being negotiated, with the d-file half-open for White and the c-file half-open for Black.
The Accelerated Dragon is one of the defining branches of the Sicilian Defence, Dragon Variation — the line you reach when both players want the full fight rather than a quiet draw.

Strategic ideas

Counter on the queenside with ...Rb8/...b5, meet h4-h5 with ...h5 or ...with ...Ne5 and ...b5 counter-strikes, and keep the bishop alive on the diagonal.
Plans & pawn structures
- 1White plays down the d-file — with no White pawn there, a rook lift and pawn lever turn this file into direct pressure on d7.
- 2Black's counterplay runs down the c-file: it is half-open for Black, so the rooks swing there to hit c2 while White is busy elsewhere.
- 3The centre is still fluid: decide early whether to lock it with a pawn advance or dissolve it with an exchange, because that choice picks the whole middlegame plan for you.
Typical middlegame structures
The main line leads to a fluid centre — one side has staked a central pawn the other must decide how to challenge, so the structure is still being negotiated. It leaves the d-file half-open for White, the c-file half-open for Black — that is where the rooks belong and where the middlegame is decided. On the pawns, Black holds a kingside pawn majority — the long-term trump to nurse into the endgame.
Traps & tactical motifs
The Dragon's ...Ng4 tricks: after h3, ...Rxc3!? queen sacrifices have decided countless blitz games.
Careless Bc4 lines fall to ...Nxe4!? — the knight grabs the centre with tactical justification.
How to Play Against the Accelerated Dragon
- Neutralise the c-file before Black owns it: challenge with your own rook, or close the file with a pawn so the opponent's main artery of play dries up.
- As White, strike at the fluid centre immediately with your own central pawn or piece pressure, before the opponent locks it into a shape that favours them.
Masters & history
Named (probably) by F.D.the name's origin is debated — some say the serpent-like shape of Black's fianchettoed position.
