Sicilian Defense Hyperaccelerated Dragon Variation
Sicilian Defense Hyperaccelerated Dragon Variation
Definition
The Hyperaccelerated Dragon is a sharp sub-line of the Sicilian Defense that begins with the moves:
1. e4 c5 2. Nf3 g6 3. d4 cxd4 4. Nxd4 Bg7
Black fianchettoes the king’s bishop on g7 before touching the queenside knight, hoping to play …d7–d5 in one stroke and thus “hyper-accelerate” the traditional Dragon setup. It is sometimes written as ECO code B27 (after 2…g6) or B34/B35 once transpositions occur.
How It Differs from Related Dragons
- Classical Dragon – starts 1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 g6.
- Accelerated Dragon – begins 1. e4 c5 2. Nf3 Nc6 3. d4 cxd4 4. Nxd4 g6.
- Hyperaccelerated Dragon – skips …Nc6 entirely in the opening phase, playing 2…g6 immediately.
By omitting …Nc6, Black keeps the c6-square free and eyes the freeing break …d5 at the earliest safe moment.
Main Line Move-Order
Typical continuations after the starting diagram are:
- 5. Nc3 Nc6 (most common) 6. Be3 Nf6 7. Bc4 O-O
- 5. c4 — White immediately establishes the Maróczy Bind. Black replies 5…Nc6 6. Be3 Nf6 7. Nc3 d6, accepting a somewhat cramped but solid structure.
- 5. Nb3, 5. Be2, and sideline gambits (e.g., 5. h4!?) are also seen in modern practice.
Strategic Ideas
For Black:
- Play …d5 in one move (e.g., …Nf6, …d5) to equalize the center without having to waste a tempo on …d6.
- Pressure the long dark-squared diagonal a1–h8 with the fianchettoed bishop.
- Typical Dragon counter-play on the c- and d-files after …Rc8 and …d5.
For White:
- Choose between an aggressive Yugoslav-style setup (Be3, Qd2, f3, 0-0-0) or the positional Maróczy Bind with c4.
- Exploit the temporarily undeveloped queenside (…Nc6 delayed) by quick piece activity—Bc4, Qf3, and sometimes Ndb5.
Historical Background
The idea of playing …g6 on move two was analyzed as early as the 1930s, but it gained practical traction in the 1960s thanks to Yugoslav and Soviet theorists. Grandmasters such as Eduard Gufeld and Dragoljub Velimirović experimented with it, but it was Gata Kamsky and later Hikaru Nakamura who popularized the line among modern elite players.
Typical Plans & Motifs
- Breakthrough …d5! – the signature move; if achieved under favorable circumstances Black equalizes instantly.
- Exchange Sacrifice on c3 – after …Rc8 and …Nxd4, …Rxc3 can crack open White’s structure, mirroring Classical Dragon themes.
- Pawn storms – if opposite-side castling occurs, White pushes h- and g-pawns, while Black advances …a5-a4-a3 or …b5-b4.
Illustrative Mini-Game
The following short grandmaster skirmish shows the dream …d5 break in action:
Famous Encounters
- Topalov – Anand, Wijk aan Zee 1998 — Anand equalized comfortably with the hyperaccelerated move-order and later won in a tactical fire-fight.
- Nakamura – So, Sinquefield Cup 2016 — showcased a modern pedigree; Wesley So neutralized Nakamura’s preparation and drew after precise play.
Interesting Facts
- The hyperaccelerated move-order sidesteps some dangerous anti-Sicilian sidelines where 2…Nc6 can be awkward, such as the Rossolimo (3.Bb5) and the Alapin (2.c3).
- Because Black delays …Nc6, the queen knight sometimes lands on d7 instead, reinforcing …f5 breaks in certain endgames.
- In online blitz, it is a favorite of speed demons who want instant counter-play without memorizing the tons of Yugoslav Attack theory that plague the Classical Dragon.

return for such an ambitious defense.
