Sicilian Dragon: Dragon Variation & Accelerated Dragon

Sicilian Defense: Dragon Variation

Definition

The Dragon is a fiercely tactical branch of the Sicilian Defense that arises after the moves 1. e4 c5 2. Nf3 d6 3. d4 cxd4  4. Nxd4 Nf6 5. Nc3 g6. Black fianchettoes the king-side bishop to g7, pointing it down the long a1–h8 diagonal. The arrangement of Black’s pawns (h7–g6–f7–e7–d6–c7) was said by Russian master Fyodor Dus-Chotimirsky in 1901 to resemble the constellation Draco—hence the evocative name.

The most heavily analysed line is the Yugoslav Attack: [[Pgn| e4|c5|Nf3|d6|d4|cxd4|Nxd4|Nf6|Nc3|g6| Be3|Bg7|f3|O-O|Qd2|Nc6|O-O-O|Bd7|Kf8|| fen|r2q1rk1/pp1bbppp/2nppn2/8/3NP3/2N1BP2/PPPQ2PP/2KR1B1R b - - 0 10 ]] The diagram shows the tabiya after 9. 0-0-0, where both sides have committed to opposite-side castling and a race to mate ensues.

Strategic Themes

  • Black aims for rapid piece activity, pressure on the central e4-pawn, and counterplay along the c- and h-files.
  • White often launches the h-pawn (h4–h5) and sacrifices on h5 or g6 to expose Black’s king.
  • Opposite-side castling makes time the most valuable resource; every tempo is potentially decisive.
  • The bishop on g7 is the soul of Black’s position—if it is exchanged or blunted, Black’s counterplay dwindles dramatically.

Typical Plans for Each Side

  • White:
    • Yugoslav pawn storm: h4–h5, g4, Bh6 exchanging the key g7-bishop.
    • Occupy the c- and d-files with rooks; sacrifice on b5 or c6 to breach the queen-side.
  • Black:
    • Push ...d5 to liberate the position or ...b5–b4 harassing the c3-knight.
    • Exchange queens (…Qa5, …Rc8, …Ne5) to defuse the attack and enter a favourable endgame thanks to the bishop pair.

Historical Notes

The Dragon first gained widespread attention in the 1940s and 1950s through the games of Mikhail Botvinnik and Yuri Averbakh, but it was Bobby Fischer who popularised the Yugoslav Attack with the legendary advice “Sac, sac, mate!” Garry Kasparov later adopted the system, contributing extensive new analysis in the 1980s.

Illustrative Game

Kasparov – Anand, PCA World Championship (Game 13), New York 1995 [[Pgn| e4|c5|Nf3|d6|d4|cxd4|Nxd4|Nf6|Nc3|g6| Be3|Bg7|f3|O-O|Qd2|Nc6|Bc4|Bd7|O-O-O|Rc8| Bb3|Ne5|h4|h5|Kb1|Rc5|Bh6|Bxh6|Qxh6|Nc4| Bxc4|Rxc4|Nd5|Nxd5|exd5|Qc7|g4|Qc5|c3|Rc8| gxh5|Bf5+|Ka1|Rxc3|hxg6|Bxg6| ]] Kasparov’s relentless kingside attack eventually broke through, showing both the power and the peril of the Dragon.

Interesting Facts

  • Although considered “refuted” more than once, the Dragon keeps resurfacing with new computer-checked nuances.
  • In Greek mythology the constellation Draco was slain by Hercules—an apt metaphor for the life-and-death nature of this opening.
  • Modern engines often evaluate the main lines near equality, yet practical results remain skewed toward decisive outcomes—draws are rare.

Sicilian Defense: Accelerated Dragon

Definition

The Accelerated Dragon is a sibling of the Dragon in which Black omits the early ...d6, aiming to play ...d5 in a single move. A typical move order is 1. e4 c5 2. Nf3 Nc6 3. d4 cxd4 4. Nxd4 g6. By “accelerating” the fianchetto, Black hopes to equalise with fewer structural weaknesses.

Main Move Order (Illustrative PGN)

After White’s most critical reply 5. c4, the position transforms into the famous Maroczy Bind: [[Pgn| e4|c5|Nf3|Nc6|d4|cxd4|Nxd4|g6|c4|Bg7| Be3|Nf6|Nc3|O-O|Be2|d6|O-O ]] White’s pawns on e4 and c4 restrict …d5, giving a spatial squeeze that Black must patiently unwind.

Strategic Themes

  • Maroczy Bind: White clamps down on the central dark squares with pawns on c4 and e4, limiting Black’s breaks.
  • Breaks for Black: …b5, …d5 (prepared with …Re8 & …Bd7), or occasionally …f5 in the endgame.
  • The minor-piece battle: Black often exchanges a knight on d4 for the c6-knight, then reroutes the remaining pieces to exploit holes on the dark squares.

Typical Plans

  • White:
    • Maintain the bind; avoid premature pawn moves that liberate Black.
    • Use space to maneuver pieces to b5, d5, or f5.
  • Black:
    • Exchange pieces to ease cramp; often trade dark-squared bishops via …Be6–…Nxd4–…Bxd4.
    • Prepare …b5 with …a5 or …Rb8, seizing the c-file afterward.

Historical Notes

The Accelerated Dragon gained popularity in the 1960s through the analyses of Yugoslav grandmaster Borislav Ivkov. In the computer era it has become a favourite of universal players such as Magnus Carlsen, who appreciate its flexibility and reduced risk compared with the full-blooded Dragon.

Illustrative Game

Carlsen – Sutovsky, European Club Cup, Kallithea 2008 [[Pgn| e4|c5|Nf3|Nc6|d4|cxd4|Nxd4|g6|c4|Bg7| Be3|Nf6|Nc3|O-O|Be2|d6|O-O|Bd7|Nc2|Rc8| f3|Qa5|Qd2|Rfe8|b4|Qd8|Rac1|a6|Kh1|Ne5| Na3|Be6|Nd5|Bxd5|cxd5|e6|Rxc8|Qxc8|dxe6 ]] Carlsen calmly exploited a small space advantage, highlighting the strategic, rather than tactical, character of the Accelerated Dragon.

Interesting Facts

  • The absence of …d6 means the Levenfish Attack (6. f4) loses its sting, giving Black one less sharp line to memorise.
  • Some theorists call 5. Nc3 Bg7 6. Nxc6 “the Hyper-Accelerated Dragon,” shaving off yet another tempo.
  • Endgame specialists like Ulf Andersson steered the opening toward long, technical endings, proving that not all Sicilians are pure tactics.
