The Indian Defence: 1.d4 Nf6 2.Nf3 arises after 1.d4 Nf6 2.Nf3 and falls under ECO code A46. This move keeps White's options open: they can first see how Black intends to play before deciding on a response. If, for example, White likes to play against the King's Indian defence with c4, but wants to avoid lines involving c4 and ...e6, they can lead with 2. Nf3 and answer 2...g6 with 3. c4 but 2...e6 with (e.g.) 3. Bg5. This position is also often reached via the move order 1.Nf3 Nf6 2.d4. Black now makes a decision as to which way they intend to develop their bishop(s). Then, White chooses which line they would like to play, generally from the options 3. c4, 3. g3 (preparing to fianchetto), 3. Bg5 or 3. Bf4, or 3. e3. 2...g6 is the most common move. Black prepares to fianchetto their kingside bishop and play in a King's Indian or Grünfeld style. White can transpose into a King's Indian with 3. c4, but other plans include 3. g3, the Przepiorka variation, 3. Bg5, the Torre attack, or 3. Bf4, the London system.

- Playing without a plan: Each position in the Indian Defence: 1.d4 Nf6 2.Nf3 demands a specific approach. Understand whether you should be attacking, defending, or maneuvering before making your move. Random moves lead to random results.
