King's Indian Defense: Fianchetto - Classical Variation
King's Indian Defense: Fianchetto Variation, Classical Variation
Definition
The King's Indian Defense (KID) begins with the moves 1. d4 Nf6 2. c4 g6. The Fianchetto Variation is characterized by White's early kingside fianchetto: 3. Nf3 Bg7 4. g3. When Black replies with the most traditional set-up …d6/…O-O/…Nbd7/…e5 (rather than immediate queenside play with …c5), the line is often labelled the Classical System of the Fianchetto. One very common move order is:
1. d4 Nf6 2. c4 g6 3. Nf3 Bg7 4. g3 O-O 5. Bg2 d6 6. O-O Nbd7 7. Nc3 e5
Typical Move Order (E60-E62 family)
- 1. d4 Nf6
- 2. c4 g6
- 3. Nf3 Bg7
- 4. g3 O-O
- 5. Bg2 d6
- 6. O-O Nbd7 (or 6…Nc6, 6…c6)
- 7. Nc3 e5 (Black stakes a classical pawn center)
Strategic Themes
- White aims for long-term positional pressure:
- Fianchettoed bishop on g2 controls the long diagonal and helps restrain …e4 breaks.
- Flexible pawn structure (d4-c4-Nc3) allows minority attacks with b2-b4-b5 or central confrontation with d4-d5.
- Black follows classic KID plans:
- …e5, …Re8, …c6, …a6 and occasionally …b5 before striking with …exd4 or …d5.
- Kingside pawn storm (…f5, …f4, …g5) is rarer than in the Main Line KID but still a thematic idea.
Why Choose the Line?
- For White: considered one of the soundest systems against the KID—less tactical mayhem, more strategic squeeze.
- For Black: keeps the quintessential King’s Indian spirit while avoiding the sharpest Samisch/4-Pawn lines.
Historical & Theoretical Significance
The Fianchetto was popularized in the 1960s by Bobby Fischer—ironically from the Black side. Its reputation for solidity led KID specialists (Gligorić, Beliavsky, Kasparov, Radjabov) to refine aggressive counter-plans. Vladimir Kramnik adopted the Fianchetto almost exclusively versus Garry Kasparov in their 1990s clashes, scoring several notable wins and draws.

- White’s b-pawn lever b2-b4-b5 undermines the c6/d6 complex.
- Black’s …exd4 break followed by …Nc5 or …Ng4 targets e4 and c4.
- Minor-piece endgames favor White due to the long-term bishop on g2 versus Black’s “bad” c8-bishop.
- If Black achieves …f5-f4, kingside dark squares (e3, g3) can become fatal weak points.
Interesting Facts
- Because the g2-bishop often remains unopposed, grandmasters sometimes call this line the “Anti-King's Indian.”
- In the 2012 Candidates, six of Levon Aronian’s eight games with White vs. the KID were Fianchetto-Classical setups—he scored +3 =3 -0.
- Engines initially underrated Black’s …a6/…b5 idea, but modern neural-net evaluations confirm it as fully playable.
- Even Magnus Carlsen, a rare 1.d4 player, adopted the Fianchetto to defeat Radjabov (a noted KID specialist) in Shamkir 2014.
