King's Indian: 3.Nc3 c6

Before the first move

The King's Indian Defense is a hypermodern battleground where Black allows White to build a massive pawn center before attacking it. By playing c6, Black keeps their options open, preparing to challenge the middle with either d5 or e5 while maintaining a flexible defensive structure.

1. d4White · your move

Push your pawn to d4. This move claims the center immediately, opens lines for your queen and dark-squared bishop, and sets the tone for a classical space advantage.

1... Nf6Black

Black replies Nf6, the most popular response to d4. By developing the knight, Black keeps White guessing. Other options like e6 (Horwitz Defense) or d5 are more direct, while the Englund Gambit with e5 is a much riskier alternative.

Other paths here: Na6 (Australian Defense) · g5 (Borg Defense: Borg Gambit) · b6 (English Defense) · e5 (Englund Gambit)

2. c4White · your move

Push your pawn to c4. This is the cornerstone of White's d4 systems, gaining more space and preparing to develop your knight behind the pawn to exert maximum control over d5.

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

Black plays g6, signaling the King's Indian or Grunfeld structures. Black could also choose e6, leading toward the Nimzo-Indian or Queen's Indian, or even the Mexican Defense with Nc6, but g6 is the most ambitious choice.

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

3. Nc3White · your move

Develop your knight to c3. This move reinforces your control over the d5 and e4 squares, preparing to complete your central dominance with a future e4 push.

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... c6Black

Black replies c6, a subtle variation within the King's Indian complex. While Bg7 is the standard move, c6 prepares to blunt the power of White's knight. You'll also frequently see d6 or d5 in this exact position.

Other paths here: d5 (Grünfeld Defense) · Bg7 (King's Indian: 3.Nc3 Bg7) · c5 (King's Indian: 3.Nc3 c5) · d6 (King's Indian: 3.Nc3 d6)

Where you stand

The position is rich with tension. White will likely push e4 to establish a full pawn center, while Black focuses on finishing development with Bg7 and castling. The battle will revolve around whether White can use their space advantage before Black can successfully undermine the center with d5 or e5.

• e2-e4 Establish a full classical pawn center
• f8-g7 Fianchetto the bishop to pressure d4
• g1-f3 Develop the knight and prepare castling
• e8-g8 Secure the king after bishop development
• d7-d5 Challenge the center supported by c6
