King's Indian Defense: Fianchetto Variation, Yugoslav Variation

Before the first move

The King's Indian Fianchetto Variation is a sophisticated, hypermodern battleground. Instead of the usual central clashes, both sides tuck their kings away and develop their bishops to the long diagonals. White seeks a solid structural advantage, while Black aims to strike at the center with timely pawn breaks.

1. d4White

White starts with d4, a solid choice that controls the center and prevents Black from immediately playing e5. It is the most common way to enter the complex world of the Indian Defenses.

1... Nf6Black · your move

Develop your knight to f6. This is the most flexible response to d4, controlling the e4 and d5 squares. You are keeping your options open, ready to react to White's next moves while preventing a quick e4.

2. c4White

White plays c4, expanding in the center and preparing to develop the knight to c3. While White could try the London System with Bf4 or the Tartakower Attack with g3 immediately, c4 is the most ambitious and traditional continuation.

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 on g7, where it will exert tremendous pressure along the long h8-a1 diagonal. This is the defining characteristic of the King's Indian Defense.

3. Nf3White

White plays Nf3, opting for a classical development path. White often plays Nc3 here to enter the main lines, but Nf3 is a common way to steer toward the Fianchetto Variation or the Saemisch if they follow up with f3 later.

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 powerful piece now breathes down the long diagonal, eyeing the center and White's queenside. It is your most important defensive and offensive piece in this opening.

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

4. g3White

White plays g3, choosing the Fianchetto Variation. This is considered one of the most reliable ways to face the King's Indian. Alternatively, White could try the Santasiere Variation with b4 or a more direct center with Nc3.

4... O-OBlack · your move

Castle kingside to bring your king to safety. This is a vital step before you begin your counterattack in the center. Your king is now well-protected behind the fianchettoed bishop.

5. Bg2White

White plays Bg2, completing the double fianchetto. The game is becoming a battle of diagonals. Both sides have very solid kingside structures, and the struggle will now shift toward the center and queenside.

5... d6Black · your move

Push your pawn to d6. This move solidifies your control over e5 and prepares to develop your queenside. It is a standard King's Indian move that keeps the center flexible.

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

6. O-OWhite

White castles, matching Black's safety. The opening phase is drawing to a close, and the strategic battle is about to begin in earnest. White's position is the definition of solidity.

6... c5Black · your move

Strike at the center with c5. This is the Yugoslav Variation. You are immediately challenging White's d4 pawn and opening lines for your queen. You are forcing White to make a decision about the central tension.

Other paths here: c6 (King's Indian: Fianchetto without Nc3, 6...c6) · Nbd7 (King's Indian: Fianchetto without Nc3, 6...Nbd7) · Nc6 (King's Indian: Fianchetto without Nc3, 6...Nc6)

7. Nc3White

White plays Nc3, developing naturally and maintaining the central tension. White could also choose to capture with dxc5, but Nc3 is more consistent with the goal of controlling the d5 square.

Other paths here: dxc5 (King's Indian: Fianchetto, Yugoslav without Nc3, 7.dxc5)

Where you stand

The position is a classic Yugoslav setup where both kings are safe and the center is tense. White will likely look to maintain the d4-c4-g3 structure, while Black will develop the queenside knight and look for counterplay on the c-file or the long diagonal. The battle often revolves around the d5 square and the activity of the dark-squared bishops.

• b8-c6 Develop the knight to pressure d4
• c3-d5 Occupy the central d5 outpost
• c1-f4 Develop the bishop to active squares
• f6-h5 Clear the f-pawn and target f4
