King's Indian Defense: Fianchetto Variation, Yugoslav Variation, Advance Line

Before the first move

The King's Indian Fianchetto Variation is a sophisticated, solid approach for both sides. White aims for long-term positional control by mirroring Black's kingside fianchetto, while Black prepares a counter-strike in the center. In this Yugoslav Panno line, the battle centers on the tension between the d4 and c5 squares.

1. d4White

White starts with d4, the most common alternative to e4. This move signals a preference for strategic, positional play over immediate tactical skirmishes. You'll need to decide how to respond to this central claim, with the King's Indian being a top-tier choice for counter-attacking players.

1... Nf6Black · your move

Develop your knight to f6. This flexible move prevents White from immediately playing e4 and prepares for a variety of setups. It is the gold standard for hypermodern players who prefer to control the center with pieces before committing pawns.

2. c4White

White plays c4, the standard follow-up to d4, aiming for total central dominance. White could also try the Tartakower Attack with g3 or the London-style f4. By choosing c4, White invites the main lines of the Indian Defenses, challenging you to find a way to break their grip.

2... g6Black · your move

Push your pawn to g6. You are preparing to fianchetto your bishop to g7, where it will exert long-range pressure across the board. This is the defining move of the King's Indian and Grunfeld defenses, signaling your intent to fight from the flanks.

3. Nf3White

White plays Nf3, a solid developing move that avoids the sharper Four Pawns Attack. White often chooses g3 immediately here, but Nf3 is the most classical approach. You must now decide whether to stick to the King's Indian or transition into a Grunfeld with d5.

3... Bg7Black · your move

Fianchetto your bishop to g7. This bishop is the soul of your position, radiating power along the h8-a1 diagonal. It defends your king and prepares to support future pawn breaks like e5 or c5 to challenge White's center.

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. This is one of the most respected ways to meet the King's Indian, aiming for a slow, maneuvering struggle. White could have played b3 or the rare Santasiere Variation with b4, but g3 is the most deeply studied path.

4... O-OBlack · your move

Castle your king to safety. This is a vital step in your development, tucking the king away and bringing your rook toward the center. In the King's Indian, your king's safety is paramount before you begin your counter-offensive in the center or on the queenside.

5. Bg2White

White plays Bg2, completing the double fianchetto. The game is now a battle of two powerful bishops. Both sides have very solid structures, and the struggle will likely revolve around who can better coordinate their pieces for the coming central tension.

5... d6Black · your move

Move your pawn to d6. This modest move is essential; it stops White from pushing e5 and prepares your own pawn breaks. It also opens a path for your light-squared bishop and solidifies your control over the e5 square.

6. O-OWhite

White castles, and the opening phase is nearing its end. Both kings are secure. The main question now is how Black will choose to strike at the center. The most common paths involve c5 or Nbd7, leading to very different types of middlegames.

6... c5Black · your move

Push your pawn to c5. You are immediately challenging White's central d4 pawn. This is the Yugoslav Variation, a sharp and active way to play. You are inviting a trade or a pawn push, both of which will change the character of the position.

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 ignoring the tension on d4 for a moment. White could have played dxc5, leading to the Exchange Variation, which is much more drawish. By playing Nc3, White keeps the game complex and full of tactical possibilities.

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

7... Nc6Black · your move

Bring your knight to c6. This move, known as the Panno Variation, puts maximum pressure on d4. You are forcing White to make a decision about the center. It's a highly active square for the knight, eyeing both b4 and d4.

8. d5White

White plays d5, the Advance Line. This gains significant space and forces the knight on c6 to relocate, usually to a5. White could have played dxc5, but that would release all the tension. Now, the battle lines are clearly drawn for a complex middlegame struggle.

Where you stand

The position is now a classic Yugoslav Panno. White has a space advantage and will likely expand on the queenside with a3 and b4. Black's plan involves relocating the knight to a5 to pressure c4, followed by a7-a6 and b7-b5 to break open the queenside. Both sides must balance their flank attacks with central stability.

• c3-a4 Knight maneuvers to control the b6 square
• c6-a5 Knight moves to a5 to pressure c4
• f3-d2 Knight moves to d2 to support b4
• a7-a6 Prepare b5 to challenge the queenside
• a1-b1 Rook supports the b-pawn expansion
