Sicilian Defense: Open Dragon Yugoslav Attack
Sicilian Defense
Definition
The Sicilian Defense is a chess opening that begins after the moves 1. e4 c5. Black immediately contests the center from the flank rather than mirroring White’s pawn on e4. By doing so, Black creates an asymmetrical pawn structure that leads to rich, combative positions.
Typical Move-Order & Sub-Branches
- 1. e4 c5 2. Nf3 (practically obligatory) and only now do the main branches appear
- 2…d6 – Najdorf, Dragon, Classical, Scheveningen, & Pirc-ish lines
- 2…Nc6 – Sveshnikov, Classical, Four Knights
- 2…e6 – Taimanov, Kan, Paulsen
- 2…g6 – Accelerated Dragon, Hyper-Accelerated
Usage in Play
The Sicilian is the most popular response to 1. e4 from club level to World Championship play because it simultaneously:
- Fights for the center with the c-pawn.
- Delays occupying e5, preserving flexibility.
- Creates imbalanced pawn structures, giving both sides winning chances.
Strategic & Historical Significance
Historically, the opening’s rise is tied to the hyper-modern revolution of the 20th century. José Capablanca once called 1…c5 “an irregular move,” but by the 1950s it completely displaced 1…e5 at elite level. Champions from Fischer, Kasparov, Anand, to Carlsen have all relied on it in critical games.
Famous Examples
• Fischer vs. Spassky, game 6, 1972 – Fischer adopted the Sicilian as White (1.e4) but had earlier used the Najdorf as Black.
• Kasparov vs. Anand, PCA 1995 (Game 11) – A dramatic Najdorf Poisoned Pawn.
• Topalov vs. Kramnik, Linares 1998 – Stunning exchange sacrifice in the Dragon.
Interesting Facts
- The Encyclopaedia of Chess Openings (ECO) devotes five full codes (B20-B99) to the Sicilian.
- Databases show that nearly 1 in 4 master-level games that start with 1.e4 end up in a Sicilian.
- Because of its reputation for decisive play, some scholastic events ban it for beginners to keep games quieter!
Open Sicilian
Definition
The term “Open Sicilian” refers to all Sicilian Defense positions that arise after White plays 2. Nf3 followed by 3. d4, exchanging the d-pawn for Black’s c-pawn: 1. e4 c5 2. Nf3 d6 (or 2…Nc6/2…e6) 3. d4 cxd4 4. Nxd4. The resulting pawn trade “opens” the c- and d-files and leads to sharp tactical play.
How It Differs From Closed or Anti-Sicilians
- Open Sicilian: White sacrifices a central pawn for rapid development; Black obtains half-open c-file pressure.
- Closed Sicilian: White withholds d4, often fianchettoing the king’s bishop (g3/Bg2).
- Anti-Sicilians: Rossolimo (3.Bb5+), Alapin (2.c3), Smith-Morra Gambit, etc., all avoid the main Open structures.
Strategic Signposts
Typical features include:
- High piece activity for both sides.
- Opposite-side castling races are common (especially in the Dragon and Najdorf).
- Black’s queenside pawn majority (a-, b-, d-pawns) vs. White’s central/kingside chances.
Illustrative Game
Kasparov – Topalov, Wijk aan Zee 1999, began 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6, entering a classic Najdorf before Kasparov unleashed his immortal 24th-move rook sacrifice.
Anecdotes
- The “Open” structure is so iconic that many databases label games simply “Sicilian: Open” when the exact sub-variation is unclear.
- Engines give roughly equal evaluations, but human statistics show that the side that first lands a concrete tactical blow often wins quickly.
Dragon Variation
Definition
The Dragon is a razor-sharp sub-line of the Open Sicilian characterized by Black fianchettoing the dark-squared bishop: 1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 g6. The bishop on g7 breathes fire down the long diagonal, said to resemble the shape of a dragon’s tail in the pawn formation (d6–e7–f7–g6–h7).
Key Ideas
- Black aims for …Bg7, …Nc6, …0-0, and thematic breaks with …d5.
- White often castles queenside and launches an h-pawn storm.
- Tactical motifs: Bxh6 sacrifices, the exchange sacrifice …Rxc3, mating nets on h7/h8.
Strategic & Historical Significance
The Dragon became infamous after the 1953 Candidates, where it featured in multiple decisive games. It later evolved into two camps: main line Yugoslav Attack (extreme violence) versus positional sidelines (e.g., Classical 6.Be2). Grandmasters like Miguel Najdorf, Bent Larsen, and Garry Kasparov wielded the Dragon, but it came under theoretical fire in the computer era, forcing Black to memorize precise move-orders.
Typical Move Sequence
Najdorf-style castling race:
6.Be3 Bg7 7.f3 0-0 8.Qd2 Nc6 9.0-0-0 — the stem of the Yugoslav Attack.
Interesting Facts
- The ECO codes for the Dragon run from B70 to B79 (main lines) and B80-B89 for Accelerated/Hyper-Accelerated cousins.
- The line’s name was coined by Austrian master Hermann Kanzler in the 19th century.
- Modern “Dragoneers” include Gawain Jones, who wrote two books advocating its revival.
Yugoslav Attack
Definition
The Yugoslav Attack is White’s most aggressive weapon against the Dragon Variation of the Sicilian. After 1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 g6 6. Be3 Bg7 7. f3 0-0 8. Qd2 Nc6 9. 0-0-0, White completes a setup of Be3-Qd2-f3-0-0-0 poised for g- and h-pawn storms, while Black counter-attacks on the c-file and center.
Purpose & Typical Plans
- White: h4-h5, g4-g5, Bh6 trading off Black’s key g7-bishop, sacrifice on h5/h7, or Nd5 tactics.
- Black: …d5 central break, …Rc8, …Qa5, and the thematic exchange sacrifice …Rxc3 to shatter the white king.
Canonical Main Line
1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 g6 6. Be3 Bg7 7. f3 O-O 8. Qd2 Nc6 9. O-O-O Bd7 10. h4 h5 11. Bc4 Rc8 12. Bb3 Ne5
Strategic & Historical Significance
Dubbed “Yugoslav” because many of its early adherents (Gligorić, Matanović, Ivkov) hailed from the former Yugoslavia, the line became the centerpiece of 1980s theoretical debates. Computers originally assessed Black’s position as perilous, yet modern engine prep has breathed new life into the Black side.
Memorable Games
• Topalov – Kasimdzhanov, FIDE WCh 2004 (Game 9): A Yugoslav Attack that decided a knockout final.
• Anand – Kasparov, Linares 1991: Kasparov’s spectacular …Rxc3!! exchange sac paved the way for victory.
• Jones – Caruana, London 2017: Contemporary theoretical duel; Black survived a dangerous onslaught with accurate defense.

Interesting Facts
- In many sub-lines, both sides castle on opposite wings before move 10 — earlier than in almost any other mainstream opening.
- Statistics show that decisive results (wins for either side) exceed 70 %, making the Yugoslav Attack a favorite among players who “play for two results.”
- The famous 1997 Kasparov vs. Deep Blue match featured a Yugoslav Attack in Game 5 — the computer surprised Kasparov with novel preparation.
