King's Indian Defense: Fianchetto Variation, Classical Variation

Before the first move

The Fianchetto Variation of the King's Indian Defense is a solid, positional approach for White. By placing the bishop on g2, White aims for long-term control of the center and safety for the king. Black, meanwhile, prepares a counter-strike in the center, typically with e5, leading to a complex battle for space and piece coordination.

1. d4White

White begins with d4, a move that focuses on central control and solid development. While e4 is the most common alternative, d4 leads to more strategic, slower-burning positions where understanding pawn structures is key.

1... Nf6Black · your move

Develop your knight to f6. This flexible move prevents White from immediately playing e4 and prepares to challenge the center. It keeps your options open for several different defensive setups.

2. c4White

White plays c4, the standard follow-up to d4, aiming for a massive central presence. White could also try the London System with Bf4 or the Tartakower Attack with g3, but c4 is the main road.

Other paths here: f4 (Canard Opening) · g4 (Indian Defense: Gibbins-Weidenhagen Gambit) · e4 (Indian Defense: Omega Gambit) · d5 (Indian Defense: Pawn Push Variation)

2... g6Black · your move

Push your pawn to g6. You are preparing to fianchetto your bishop to g7, which is the hallmark of the King's Indian Defense. This bishop will become a long-range monster on the h8-a1 diagonal.

Other paths here: g5 (Indian Defense: Medusa Gambit) · b5 (Indian Defense: Pyrenees Gambit) · a6 (Indian: 2.c4 a6) · Nc6 (Mexican Defense)

3. Nf3White

White chooses Nf3, a solid developing move. White often plays Nc3 here to enter the Saemisch or Classical main lines, but Nf3 is the gateway to the Fianchetto Variation we are studying.

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

Bring your bishop to g7. Your bishop is now perfectly placed to exert pressure on the central squares, particularly d4, and provides a sturdy shield for your future castled king.

Other paths here: d5 (Neo-Grünfeld Defense: with Nf3) · d6 (King's Indian: 3.Nf3 d6)

4. g3White

White plays g3, entering the Fianchetto Variation. By avoiding the sharpest lines, White seeks a steady positional edge. Rarer tries here include b3 or the aggressive Santasiere Variation with b4.

Other paths here: b4 (King's Indian Defense: Santasiere Variation) · b3 (King's Indian: b3 System)

4... O-OBlack · your move

Castle your king to safety. By tucking the king away now, you complete your kingside development and prepare to focus entirely on the upcoming central confrontation.

5. Bg2White

White follows through with Bg2. Both sides have now fianchettoed their kingside bishops, leading to a symmetrical look where the struggle for the center will decide who holds the advantage.

5... d6Black · your move

Move your pawn to d6. This modest-looking move is vital; it controls e5 and c5, prepares to develop your light-squared bishop, and sets the stage for your primary central break.

Other paths here: c6 (Neo-Grünfeld Defense: Classical Variation, Original Defense) · d5 (Neo-Grünfeld Defense: Delayed Exchange Variation)

6. O-OWhite

White castles, completing the initial development. White's position is harmonious and lacks obvious weaknesses. Now the focus shifts to how White will deploy the remaining pieces on the queenside.

6... Nbd7Black · your move

Develop your knight to d7. This knight supports the e5 pawn push and remains flexible. From d7, it can jump to c5 or b6 later to harass White's center or queenside.

Other paths here: c5 (King's Indian Defense: Fianchetto Variation, Yugoslav System) · c6 (King's Indian: Fianchetto without Nc3, 6...c6) · Nc6 (King's Indian: Fianchetto without Nc3, 6...Nc6)

7. Nc3White

White develops the last minor piece with Nc3. White sometimes delays this with Qc2 to keep the c-file clear, but Nc3 is the most direct way to control the center.

Other paths here: Qc2 (King's Indian: Fianchetto without Nc3, 6...Nbd7 7.Qc2)

7... e5Black · your move

Push your pawn to e5. This is the thematic strike of the King's Indian. You are challenging White's d4 pawn directly and opening lines for your queen and bishop.

8. e4White

White plays e4, meeting Black's challenge head-on. This leads to the main line of the Classical Fianchetto. White could also choose to maintain the tension with h3 or Re1.

Where you stand

The position is a classic King's Indian battle. White enjoys a space advantage and a very safe king, while Black has a solid position with clear counterattacking chances. Black will likely look to pressure d4 with Re8 and c6, while White will aim for queenside expansion or a central breakthrough. Both sides must balance their attacking ambitions with careful prophylactic play.

• f8-e8 Place the rook on e8 to pressure e4
• d7-c5 Route the knight to c5 to attack e4
• c1-e3 Develop the bishop to support the center
• f3-d2 Reposition the knight to support queenside expansion
• a1-b1 Prepare b4 to gain space on the queenside
