Sicilian Dragon: 6.Be3 Bg7 7.Bc4 O-O
Sicilian Defense, Dragon Variation: 6.Be3 Bg7 7.Bc4 O-O
Definition
The sequence of moves 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 g6 6.Be3 Bg7 7.Bc4 O-O leads to one of the sharpest branches of the Sicilian Defense—the Dragon Variation. The characteristic features are:
- Black fianchettoes the king’s bishop on g7, shaping the “dragon” on the long diagonal (h8–a1).
- White adopts the Yugoslav Attack setup with Be3, Qd2, f3, and long castling, aiming a pawn storm at the black king.
- The move 7…O-O (instead of 7…Nc6, 7…Bd7, or 7…a6) commits Black’s king to the g7-corner immediately, clarifying the battleground on opposite wings.
Usage in Play
This line is a favorite of players who thrive on highly tactical, two-result positions. It is regularly employed:
- As Black—to unbalance the game early and seize dynamic counterplay on the c- and h-files.
- As White—to test Black’s theoretical preparation; one slip can lead to a swift mating attack.
Strategic Themes
The Dragon stakes everything on activity:
- Long diagonal pressure: The g7-bishop targets c3 and d4, often supporting …d6-d5 breaks.
- Exchange sacrifice: …Rxc3 is an evergreen motif that rips open the white king after castling queenside.
- Opposite-wing pawn storms: White pushes h4-h5 and g4-g5; Black counters with …a6, …b5, …b4.
- Piece placement: Knights frequently maneuver to e5/c4 (for Black) and d5/f5 (for White) as outposts.
Historical Significance
The name “Dragon” was coined by Russian master Fyodor Dus-Chotimirsky (≈1901), who likened Black’s pawn structure (g6-d6-e7) to the constellation Draco. From the 1950s to the early 2000s it was a mainstay at elite level—Fischer, Tal, Kasparov, Topalov, and Nakamura have all aired it. The line with 7…O-O in particular gained notoriety after:
- Karpov – Kortchnoi, Candidates 1974: Karpov’s precise Yugoslav Attack foreshadowed the long strategic battles both would fight.
- Kasparov – Deep Blue, 1996 (Game 1): Showed the engine’s readiness to enter razor-sharp Dragons.
- Topalov – Beliavsky, Linares 1994: A textbook …Rxc3 exchange sacrifice leading to victory.
Example Line
A representative continuation highlighting typical ideas:
After 19…Rxc3! Black sacrifices the exchange to ruin White’s king shelter and activate the queen and bishop pair.

Interesting Facts
- Many modern grandmasters avoid the Dragon in must-win games as White’s prep can be lethal, yet it remains a favorite in rapid and blitz.
- The line is so forcing that several theoretical innovations have emerged from computer engine matches rather than human creativity.
- The move order with 7.Bc4 foils some of Black’s sidelines (e.g., the Chinese Dragon with …a6) because the c4-bishop immediately eyes f7.
- Hikaru Nakamura once quipped, “If you want a quiet life, don’t play 7…O-O.”
When to Choose This Variation
Opt for 6…Bg7 7.Bc4 O-O if:
- You are well-prepared for the latest Yugoslav Attack theory (notably the 9.0-0-0 d5 sacrificial lines).
- You relish tactical complications and don’t mind defending precise attacks against your king.
- In team events, you need double-edged winning chances with Black.
Conversely, select quieter Sicilians (e.g., Scheveningen or Classical) if you prefer strategic manoeuvring and reduced tactical risk.
Summary
The Dragon with 6.Be3 Bg7 7.Bc4 O-O is an iconic, high-octane battleground in chess opening theory. Mastery of its razor-sharp lines rewards the adventurous with rich tactical possibilities—and punishes the unprepared with fiery defeats.
