King's Indian: 4.g3

Before the first move

The King's Indian Defense is a hypermodern battleground where Black allows White to build a massive center, planning to strike back later. By choosing the Fianchetto Variation with 4.g3, White aims for a solid, long-term positional squeeze, mirroring Black's bishop to neutralize the power of the g7-square.

1. d4White · your move

Push your pawn to d4. This move stakes an immediate claim in the center and opens paths for your queen and dark-squared bishop. It is the foundation for many strategic systems where you control the pace of the game.

1... Nf6Black

Black replies with Nf6, the most popular and flexible defense. By developing the knight, Black controls e4 and d5 without committing any pawns yet. Other choices like e6 (the Horwitz Defense) or d5 (the Queen's Gambit Declined) lead to very different structures.

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 move, known as the Queen's Gambit style of play, increases your influence over the d5-square and prepares to develop your knight behind the pawn. It signals that you are building a broad, classical center.

2... g6Black

Black plays g6, signaling an intent to play the King's Indian Defense. This hypermodern approach allows White to take the center now with the hope of destroying it later. Alternatives like e6 or c5 would lead to the Queen's Indian or Benoni structures respectively.

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 puts pressure on the d5 and e4 squares and prepares to support a further central advance. It is a natural developing move that keeps Black guessing whether you will play e4 or g3.

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 plays Bg7, completing the fianchetto. This is the defining move of the King's Indian. White now has a major choice: the aggressive Four Pawns Attack with f4, the Classical Variation with Nf3 and e4, or the solid Fianchetto Variation we are exploring.

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. g3White · your move

Push your pawn to g3. You are preparing to place your own bishop on g2. This 'Fianchetto Variation' is one of the most reliable ways to face the King's Indian, as your bishop on g2 blunts the power of Black's bishop on g7.

Other paths here: Bf4 (King's Indian: 4.Bf4) · Bg5 (King's Indian: 4.Bg5) · Nf3 (King's Indian: 4.Nf3) · e4 (King's Indian Defense: Normal Variation)

Where you stand

The game has reached the starting point of the Fianchetto Variation. White will develop the bishop to g2 and castle kingside, seeking a stable advantage. Black usually castles and then chooses between the central strikes d6 and e5 or the more forcing d5, which would lead to a Grünfeld-style structure. Both sides have clear, long-term strategic goals.

• f1-g2 Place the bishop on the long diagonal
• g1-f3 Develop the knight and prepare castling
• e8-g8 Secure the king behind the fianchetto
• d7-d6 Prepare the e5 central pawn strike
• c1-e3 Develop the dark bishop to control d4
