Sicilian Defense: Taimanov, Szen, Modern Line
Sicilian Defense
Definition
The Sicilian Defense arises after the moves 1. e4 c5. Black immediately contests the d4-square from the flank instead of mirroring White’s pawn with 1…e5. Its asymmetrical pawn structure leads to unbalanced positions rich in tactical as well as strategic possibilities.
Typical Move Order & Main Branches
After 1.e4 c5 the game can branch into a vast family of systems. The most frequently encountered continuations are:
- 2.Nf3 followed by 3.d4 (Open Sicilians) – e.g. the Najdorf, Scheveningen, Dragon, Paulsen/Taimanov, etc.
- Closed lines beginning with 2.Nc3 or 3.g3.
- Anti-Sicilians such as 2.c3 (Alapin) or 2.Nf3 Nc6 3.Bb5+ (Rossolimo).
Strategic Significance
Because Black avoids immediate symmetry, he often gains:
- A semi-open c-file for counter-play against White’s queenside.
- Dynamic pawn breaks (…d5 or …b5) compensating for the spatial deficit.
- Complex middlegame positions where one good plan can outweigh modest opening inaccuracies.
Conversely, White usually enjoys space and a lead in development, aiming for a direct attack on the kingside or centre.
Historical Notes
The opening was already known in the 16th century (Polerio, Greco) but gained real prominence after the 1851 London tournament, where Adolf Anderssen used it successfully. It became a mainstay of 20th-century grandmaster practice—employed by world champions from Fischer and Kasparov to Carlsen.

Interesting Facts
- Roughly one in five master-level games begins with 1…c5, making the Sicilian the single most popular response to 1.e4.
- Computer analysis confirms its fighting nature: Black scores closer to 50 % in the Sicilian than in any other 1…e5 alternative.
Taimanov Variation (Sicilian Defense)
Definition
The Taimanov Variation is an Open Sicilian characterized by the flexible move …Qc7 in combination with …Nc6 and …e6. A canonical starting sequence is:
1.e4 c5 2.Nf3 e6 3.d4 cxd4 4.Nxd4 Nc6 5.Nc3 Qc7
Origins & Naming
Named after Soviet Grandmaster Mark Taimanov (1926-2016), who developed its modern treatment in the 1950s-60s, the line is also grouped under the broader “Paulsen System,” honouring Louis Paulsen’s 19th-century experiments.
Strategic Ideas
- Flexibility – By delaying the kingside knight, Black can choose between …Nf6, …g6, or …Bb4 depending on White’s setup.
- Pressure on c-file – …Qc7 fingerprints the queen on an optimal diagonal and supports a later …d5 break.
- Balanced Development – Black’s minor pieces gravitate to c6, d7, and e7, harmonizing piece activity with sound pawn structure.
Typical Continuations
- 6.Be3 (English Attack themes)
- 6.Be2 – the Szen Variation (see next section)
- 6.g3 – Fianchetto line
Famous Game Reference
Kasparov – Anand, Linares 1993, featured the sharp 6.Be3 a6 7.Qd2 Nf6 8.0-0-0 Bb4, showcasing the typical race of tempi on opposite wings.
Interesting Anecdotes
- Mark Taimanov used “his” opening in the only game he won against Fischer during their 1971 Candidates match—unfortunately defaulted to a loss because of a later forfeiture streak.
- Owing to its solid yet tactical nature, the variation is a favourite of many young engines that value flexibility before commitment.
Szen Variation (6.Be2 Line in the Taimanov)
Definition
The Szen Variation occurs after:
1.e4 c5 2.Nf3 e6 3.d4 cxd4 4.Nxd4 Nc6 5.Nc3 Qc7 6.Be2
It is named after the 19th-century Hungarian master József Szén (1805-1857), one of the early adopters of a restrained development scheme against the Sicilian.
Strategic Features
- Modesty first – By placing the bishop on e2 instead of g2 or c4, White keeps the position compact, avoiding immediate theoretical skirmishes.
- Rapid Castling – 7.0-0 followed by f4 or f3 lends flexibility to launch a later kingside pawn storm while keeping the king safe.
- Broad move-order transpositions – The setup can transpose into Scheveningen, Kan, or even English Attack structures depending on Black’s replies.
Sample Miniature
Plans for Each Side
White may choose between:
- Quiet central build-up with Kh1, f4, Be3, Qe1-h4.
- English-Attack-style aggression if Black delays …d6.
Black typically replies:
- 6…a6 7.0-0 Nf6 (Modern Line)
- 6…Nf6 7.0-0 Bb4 for a pin-based strategy.
Interesting Facts
- Because it sidesteps razor-sharp theory, the Szen Variation has been a popular surprise weapon for grandmasters who normally avoid heavy Sicilian main lines.
- Its ECO code is B46.
Modern Line of the Szen Variation
Definition & Move Order
The so-called “Modern Line” refers to the most fashionable continuation after the Szen move 6.Be2:
1.e4 c5 2.Nf3 e6 3.d4 cxd4 4.Nxd4 Nc6 5.Nc3 Qc7 6.Be2 a6 7.0-0 Nf6 8.Be3
Black delays …d6, prioritizing queenside space with …a6 and rapid piece activity.
Strategic Nutshell
- Queenside vs. Kingside – Black’s …b5-b4 expansion meets White’s f-pawn push, often leading to pawn-storm races.
- Flexible King Placement – Either side can reconsider castling direction even after committing (White may still castle long in some sub-lines).
- Central Tension – The timing of …d6 and …d5 is crucial; meanwhile White chooses between e4-e5 or f4-f5 breaks.
Contemporary Practice
Top grandmasters such as Fabiano Caruana and Maxime Vachier-Lagrave have played the Modern Line with both colours, indicating its double-edged yet fundamentally sound character.

Interesting Tidbits
- The move 8.Be3 was once considered harmless; computer engines have since uncovered numerous tactical resources reviving the line for White.
- Because the Modern Line keeps both sides’ pawn structures intact for a long time, endgame chances often remain rich even after early piece trades.
