King's Indian Defense: Fianchetto Variation, Delayed Fianchetto

Before the first move

The King's Indian Defense is a hypermodern battleground where Black allows White to build a massive center, only to strike back later. In the Fianchetto Variation, White chooses a solid, positional approach by mirroring Black's kingside setup to neutralize the power of the dark-squared bishop.

1. d4White

White starts with d4, a move that immediately stakes a claim in the center. Unlike the sharper e4 lines, this often leads to more closed, maneuvering games. You will have to decide how to challenge this central control, with the Nimzo-Indian or King's Indian being popular responses.

1... Nf6Black · your move

Develop your knight to f6. This is the most flexible response to d4, preventing White from immediately playing e4 and keeping your options open. You are preparing to challenge the center while staying ready for several different defensive setups.

2. c4White

White plays c4, expanding their central influence and preparing to develop the queen's knight. This is the main line of the Indian defenses. White could have tried the London System with Bf4 or even the Tartakower Attack with g3, but c4 is the most ambitious try.

2... g6Black · your move

Push your pawn to g6. You are preparing to fianchetto your bishop on g7, which is the defining characteristic of the King's Indian and Grunfeld defenses. This bishop will become a long-range sniper aimed directly at White's central pawns.

3. Nc3White

White plays Nc3, developing a piece and preparing to seize more space. Black must now decide between the King's Indian with Bg7 or the Grunfeld Defense with d5. White could also have played g3 immediately to enter the Fianchetto Variation without committing the knight yet.

Other paths here: d5 (Indian Defense: Anti-Grünfeld, Advance Variation) · f3 (Indian Defense: Anti-Grünfeld, Alekhine Variation) · h4 (Indian Defense: Anti-Grünfeld, Basman-Williams Attack) · g3 (King's Indian Defense: Fianchetto Variation, Immediate Fianchetto)

3... Bg7Black · your move

Fianchetto your bishop to g7. This piece is the soul of your position, exerting pressure across the entire board. From here, it defends your king and prepares to support a future pawn strike against White's center.

Other paths here: d5 (Grünfeld Defense) · c5 (King's Indian: 3.Nc3 c5) · c6 (King's Indian: 3.Nc3 c6) · d6 (King's Indian: 3.Nc3 d6)

4. Nf3White

White plays Nf3, a flexible developing move that avoids committing too early to a specific pawn structure. White could have played e4 immediately to enter the Classical lines, or Bg5 to try the Smyslov Variation, but Nf3 keeps the tension high and the plans hidden.

Other paths here: Bf4 (King's Indian: 4.Bf4) · Bg5 (King's Indian: 4.Bg5) · g3 (King's Indian: 4.g3) · e4 (King's Indian Defense: Normal Variation)

4... d6Black · your move

Push your pawn to d6. This move is essential in the King's Indian to stop White from playing e5 and to prepare your own central counter-strike, usually with the e5 or c5 pawn breaks. It also opens a path for your light-squared bishop.

Other paths here: O-O (King's Indian: 4.Nf3 O-O)

5. g3White

White plays g3, entering the Fianchetto Variation. By mirroring your setup, White hopes to blunt your bishop's power on the long diagonal. This is a very deep system where White often avoids the tactical storms found in the Classical or Saemisch lines.

Other paths here: Bg5 (King's Indian Defense: Smyslov Variation) · e3 (King's Indian: 4.Nf3 d6 5.e3)

Where you stand

The game has reached a refined positional struggle. White will fianchetto the light-squared bishop to secure the kingside, while Black typically prepares the e5 or c5 break to challenge the center. Both sides have solid structures, and the battle will revolve around subtle piece maneuvering and timing the central pawn advances correctly.

• f1-g2 Fianchetto the bishop to solidify the kingside
• e1-g1 Castle kingside to complete early development
• e8-g8 Secure the king before launching a counter-strike
• e7-e5 Challenge the center with the e5 pawn push
• c8-f5 Develop the bishop to an active square
