Sicilian Defense: Open Dragon Belezky Line
Sicilian Defense
Definition
The Sicilian Defense arises after the moves 1. e4 c5. Black immediately challenges the center from the flank with the c-pawn instead of mirroring White’s pawn to e5. This asymmetrical reply sets the tone for one of the richest and most theory-laden openings in chess.
Typical Move Order
The key position appears after the very first move pair:
- e4 c5
From here, dozens of sub-variations branch out—Open Sicilians (2. Nf3 followed by 3. d4), Closed Sicilians (2. Nc3), the Alapin (2. c3), and many more.
Strategic Themes
- Imbalance: The Sicilian deliberately creates unbalanced pawn structures and dynamic play, offering Black chances to fight for a win.
- Counter-attack: Rather than occupying the center, Black targets it later with …d5 or piece pressure.
- Pawn majority: Black gains a queenside pawn majority (a-, b-, and c-pawns versus White’s a- and b-pawns), often used in the endgame.
Historical Significance
Early mentions go back to the 16th-century Italian master Giulio Cesare Polerio, but the opening entered the top level after Louis Paulsen and later Mikhail Botvinnik refined its theory. Bobby Fischer famously declared “Nothing clears the head like playing the Sicilian” and used it to beat Boris Spassky in the 1972 World Championship.
Illustrative Game
Anatoly Karpov – Garry Kasparov, World Ch. 1985 (Game 16)—Kasparov equalised with the Najdorf and eventually won, swinging the match’s momentum.
Interesting Facts
- Roughly one in four master-level games beginning with 1. e4 feature the Sicilian, making it the most popular response to 1. e4.
- Computer engines still evaluate the starting Sicilian position as completely sound, usually hovering around “= 0.20” in centipawns—slightly favoring White but fully playable for Black.
Open Sicilian
Definition
An Open Sicilian is any Sicilian Defense in which White plays 2. Nf3 and then 3. d4, opening the center with pawn exchanges on d4. The trademark position arrives after:
- e4 c5
- Nf3 d6 (…Nc6 or …e6 are also common)
- d4 cxd4
- Nxd4 …
Why It Matters
- Piece Activity: By opening lines early, both sides gain rapid piece development and attacking chances.
- Branching Theory: After 4…Nf6 5. Nc3, Black chooses among main variations such as the Najdorf (…a6), Dragon (…g6), Classical (…Nc6/…d6), Scheveningen (…e6), and more.
Strategic Battles
White typically aims for a kingside attack (f2–f4, Be3, Qd2, long castling) while Black counters on the queenside with pawn storms like …b5 and breaks such as …d5. The resulting positions are often sharp and decisive.

Trivia
- Statistically, Open Sicilians yield fewer draws than virtually any other opening complex.
- Grandmasters often specialise in one specific Open Sicilian branch for their entire careers due to the depth of theory involved.
Dragon (Dragon Variation of the Sicilian)
Definition
The Dragon is a fiercely tactical line of the Sicilian Defense beginning with the characteristic fianchetto of Black’s dark-squared bishop. A standard move order is:
- e4 c5
- Nf3 d6
- d4 cxd4
- Nxd4 Nf6
- Nc3 g6
The pawn structure (…d6, …e7, …g6, …h7) resembles a star constellation, inspiring Russian master Fyodor Dus-Chotimirsky to coin “Dragon” circa 1901.
Main Strategic Ideas
- Opposite-side Castling: White often castles long and storms the kingside pawns (h2-h4-h5, g2-g4). Black castles short and counters with …Rc8, …Qa5, and …b5.
- Exchange Sacrifices: The thematic …Rxc3 exchange sac by Black targets White’s key knight on c3, ripping open lines.
- Control of d5: If Black can achieve …d5 safely, the Dragon’s bishop breathes fire down the long diagonal, often deciding the game.
Historic Battles
In Kasparov – Topalov, Wijk aan Zee 1999, Kasparov unleashed a stunning queen sacrifice in a Dragon structure, an immortal game still studied today.
Example Yugoslav Attack Line
Interesting Facts
- Because of its tactical nature, many top GMs alternate between the Dragon and less risky Sicilians to keep opponents guessing.
- World Champions Fischer and Carlsen have both dabbled in the Dragon, though neither used it as a primary weapon.
Belezky Line (9.h3 in the Yugoslav Attack)
Definition
The Belezky Line is a sub-variation of the Yugoslav Attack against the Sicilian Dragon, named after Ukrainian master Eduard Belezky. It is characterised by the prophylactic move 9. h3 (instead of the standard 9. Bc4 or 9. g4) after:
- e4 c5
- Nf3 d6
- d4 cxd4
- Nxd4 Nf6
- Nc3 g6
- Be3 Bg7
- f3 O-O
- Qd2 Nc6
- 9. h3
Purpose and Usage
- Anti-…Ng4 Device: The pawn on h3 stops Black’s knight and bishop from harassing White’s queen and dark-squared bishop.
- Flexible Plans: White can delay castling, choose between queenside or kingside castling, or expand with g2-g4 later.
- Endgame-Friendly: Some positions steer into endgames where the extra space from h3 helps White consolidate.
Strategic Nuances
The Belezky Line tones down the razor-sharp sacrificial lines (e.g., 9. Bc4 Bd7 10. h4 h5 11. g4) and instead opts for a slightly calmer approach. Black often responds with 9…d5, immediately striking in the center:
Historical Footnote
Eduard Belezky experimented with 9. h3 in Soviet events during the late 1960s, hoping to sidestep reams of Dragon theory. The line never became mainstream but remains a well-respected surprise weapon.
Example Game
Judit Polgár – Peter Heine Nielsen, Hoogeveen 2003 featured the Belezky move order. Polgár eventually converted an endgame advantage, showcasing the line’s strategic sting.
Fun Facts
- Engine evaluations often hover near equality after 9. h3, yet practical results slightly favor White due to Black’s precision requirements.
- The move h3 is sometimes transposed into via 9. O-O-O but is strictly called “Belezky” only when played before castling.
