1.d4 Nf6 2.Nf3 g6 opens the Indian Defence: 1.d4 Nf6 2.Nf3... g6, ECO A48. White holds back the c-pawn and Black holds back the d-pawn — a mutual waiting game that keeps every major Indian Defense alive. The first side to commit a pawn dictates the structure.
Strategic Overview
This is a flexible position because both sides are deliberately uncommitted. White hasn't played c4, which means the King's Indian and Grünfeld are still latent rather than active. Black hasn't played ...d5 or ...d6, which means the choice between Grünfeld (active center) and King's Indian (fianchetto with delayed center) is still open. White's main options are 3.c4 (transposing into mainstream Indian Defense theory), 3.g3 (a quieter setup heading for a King's Indian Attack-style game), and 3.Bf4 or 3.Bg5 (Anti-Indian systems that try to disrupt Black's plans before they crystallize). The interesting feature of this position is that both sides can use it to dodge their opponent's preparation. A Black player who doesn't want to face the Bayonet Attack or Mar del Plata Variations of the King's Indian can use this move order to steer toward something else. A White player who doesn't want to memorize Grünfeld theory can play 3.g3 and head for a quieter game. The middlegame character depends entirely on which transposition both sides agree to. There's no single strategic theme — the opening is a launching pad for many different middlegame structures.
Key Ideas
The recurring motifs below distinguish a confident handler of this opening from a beginner:
- Mutual waiting game preserves all options — Neither side has committed to the structure that defines mainstream Indian Defense theory. Both sides are dodging preparation by keeping pawn moves flexible.
- 3.c4 returns to mainstream theory — If White plays c4, the game transposes into normal King's Indian, Grünfeld, or related Indian Defense lines. This is the principled but most theoretical path.
- 3.g3 heads for a quieter game — Fianchetto setups without c4 give White a flexible structure resembling a King's Indian Attack. The game becomes slower and more strategic than mainstream Indian theory.
- Anti-Indian setups with Bf4 or Bg5 — Developing the queen's bishop early lets White avoid Indian theory entirely. The resulting positions are more positional and less concrete than mainstream lines.

Common Mistakes
- Neglecting development — It can feel productive to make extra pawn moves early, but falling behind in piece development is what loses most amateur games — especially in open positions where active pieces find squares fast.
- Letting White own the centre — Hypermodern openings concede central space on purpose, but only if you strike back in time. Delay the counter-blow and you end up squeezed.
