Sicilian: Taimanov, 6.g3 a6 7.Bg2 d6 8.O-O
Sicilian Defense – Taimanov Variation, 6.g3 a6 7.Bg2 d6 8.O-O
Definition
The sequence of moves 1. e4 c5 2. Nf3 e6 3. d4 cxd4 4. Nxd4 Nc6 5. Nc3 Qc7 6. g3 a6 7. Bg2 d6 8. O-O defines a particular branch of the Sicilian Defense, Taimanov Variation. By fianchettoing the king’s bishop with 6.g3 and 7.Bg2, White steers play into quieter, strategically rich waters compared with the razor-sharp main lines of the Sicilian. It is sometimes called the Fianchetto Taimanov.
Move Order & Basic Ideas
- 6.g3 – White prepares to place the bishop on g2, locking down the long diagonal and discouraging …d5 breaks.
- …a6 – Black follows the standard Taimanov plan: keep the knight on c6 flexible and prepare …b5, …Bb7, or …Nge7.
- 7.Bg2 d6 – The bishop reaches its ideal square; Black fortifies the e5-square and keeps options open for …Nf6 or …g6.
- 8.O-O – White completes development, eyeing central breaks with f4 or e5 and queenside expansion with a4.
Strategic Themes
Unlike the sharper English Attack setups (Be3, f3, Qd2, 0-0-0), the fianchetto line emphasises piece activity and control of key squares over a direct pawn storm.
- Control of d5. White’s Bg2 and Nc3 put tremendous pressure on d5; Black must time …d5 precisely.
- Flexible pawn breaks. White can choose between f4-f5, e4-e5, or even c4, depending on Black’s setup.
- Queenside minority attack. Moves like a4 and a5 can undermine Black’s …b5 expansion.
- Piece play. Both sides often manoeuvre knights to d5/e4 (White) or e5/c4 (Black).
Typical Plans
- For White
- Re1, a4, Be3, h3 to over-protect g4.
- Fianchetto pressure: Qe2, Rd1, Bf4, gaining space.
- Occasional pawn storm with f4-f5 if Black castles short.
- For Black
- Traditional Taimanov: …Nf6, …Be7, …O-O, then break with …d5.
- Scheveningen pivot: …Nge7, …g6, …Bg7 leading to a “Hedgehog” structure.
- A more dynamic approach: …b5, …Bb7, placing a rook on c8 and sacrificing a pawn for activity if necessary.
Historical & Theoretical Significance
The line bears the name of GM Mark Taimanov, a leading Soviet theoretician of the 1960s–70s who systematised the …Qc7 ideas in the Sicilian. The 6.g3 plan, however, gained popularity later when players such as Vladimir Kramnik and Peter Leko sought reliable anti-Sicilian weapons in the late 1990s. Its slow-burn nature meshes well with modern engine preparation, allowing White to play for two results with minimal risk.
Notable Examples
- Kramnik vs. Shirov, Dortmund 1998 – Kramnik demonstrated a model a4 minority attack, squeezing out a positional win in 39 moves.
- Anand vs. Topalov, Wijk aan Zee 2004 – Anand’s rapid central break with e5 gave him enduring initiative, highlighting the power of the Bg2-bishop.
- Caruana vs. Carlsen, Gashimov Memorial 2019 – A high-level draw where both sides followed cutting-edge engine lines into a balanced but rich endgame.

Interesting Facts & Anecdotes
- In the Kasparov vs. Deep Blue match (1997) Kasparov considered using the 6.g3 Taimanov as a “risk-free” testing ground against the computer’s tactical prowess but ultimately opted for 1.d4 systems instead.
- The move 6.g3 temporarily blocks the queen on d1 from defending the d-pawn, a nuance that has trapped several inattentive club players after …Nxd4?! Fortunately, 7.Qxd4! restores balance.
- Because the bishop is already fianchettoed, castling queenside is rare for White, making the game less double-edged than many Sicilians.
Why Choose (or Avoid) This Line?
Choose it if you like positional squeeze, endgame skills, and don’t mind manoeuvring. Avoid it if you crave immediate fireworks; Black can equalise with accurate play, so patience is essential.
