King's Indian: 5.Nf3 c5

Before the first move

The King's Indian Defense is a hypermodern battleground where Black allows White to build a massive pawn center, only to strike back at it later. In this specific line, Black uses an early c5 to challenge your central control immediately, leading to sharp, strategic tensions where every tempo counts.

1. d4White · your move

Push your pawn to d4. This move claims the center and opens paths for your queen and dark-squared bishop, setting the stage for a classical approach to the opening.

1... Nf6Black

Black replies with Nf6, the most popular way to meet d4. By avoiding an immediate d5, Black maintains flexibility. You might also see the Englund Gambit with e5 or the solid Horwitz Defense with e6 at this early stage.

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

2. c4White · your move

Advance your pawn to c4. This is the standard follow-up to d4, gaining more space and preparing to develop your knight behind the pawn to support your central dominance.

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 chooses g6, signaling the intent to enter a King's Indian or Grunfeld structure. Other tries like the Mexican Defense with Nc6 or the Queen's Indian with b6 offer very different pawn structures for you to face.

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

Bring your knight to c3. This move develops a piece toward the center and prepares the e4 push, which would give you a full classical pawn center.

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

Black completes the fianchetto with Bg7. This is the soul of the defense. At this point, you could also consider the Grunfeld with d5 or the more direct c5, but the bishop move is the most consistent.

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. e4White · your move

Push your pawn to e4. You have successfully established a powerful three-pawn center. This move claims space and prepares for your kingside development.

Other paths here: Bf4 (King's Indian: 4.Bf4) · Bg5 (King's Indian: 4.Bg5) · g3 (King's Indian: 4.g3) · Nf3 (King's Indian: 4.Nf3)

4... d6Black

Black plays d6, a necessary stabilizing move. Without it, White's e-pawn would be a constant threat to advance. While castling immediately is possible, d6 is the standard way to keep the center under control.

Other paths here: O-O (King's Indian: 4.e4 O-O)

5. Nf3White · your move

Develop your knight to f3. This natural move reinforces d4 and e5 while preparing for kingside castling. You are completing your development with a very harmonious position.

Other paths here: Bg5 (King's Indian Defense: Accelerated Averbakh Variation) · Nge2 (King's Indian Defense: Kramer Variation) · Bd3 (King's Indian: 4.e4 d6 5.Bd3) · h3 (King's Indian Defense: Makogonov Variation)

5... c5Black

Black strikes with c5, an aggressive alternative to the main line of castling. You must now decide whether to push d5, capture on c5, or simply develop and keep the tension in the center.

Other paths here: Bg4 (King's Indian: 5.Nf3 Bg4) · Nbd7 (King's Indian: 5.Nf3 Nbd7) · O-O (King's Indian: 5.Nf3 O-O)

Where you stand

The position is highly tactical. White usually pushes d5 to gain a space advantage, leading to Benoni-style structures where White attacks on the queenside while Black seeks counterplay on the kingside. Both sides must balance their central control with the need for rapid piece activity and king safety.

• d4-d5 Push d5 to gain space and lock the center.
• f1-e2 Develop the bishop to e2 before castling.
• e8-g8 Castle kingside to secure the black king.
• c8-g4 Pin the knight to undermine the d4 pawn.
