The Indian Game Mainlines arises after 1.d4 Nf6 and falls under ECO code A45. With 1...Nf6, Black develops a piece and gains control of e4 without yet committing any pawn to the centre, making it the most flexible answer to 1. d4. This leaves open the possibility of a classical pawn challenge later, or a hypermodern strategy in which Black controls the centre from a distance with pieces, allowing White to build a pawn centre only to undermine it with well-timed pawn thrusts. White retains broad freedom to develop pieces or expand further in the centre, and the resulting positions offer extensive transpositional potential. White's main continuation is 2. c4, grabbing additional space and securing influence over d5, after which a knight can be developed behind the pawn chain with the aim of eventually playing e4. Black may directly contest the centre with 2...d5, 2...c5 (Benoni), or 2...e5 (Budapest), but more commonly advances pawns only as needed to develop the bishops through 2...e6, 2...g6, 2...d6, or 2...b6. With 231.8 million Lichess games across all rating levels, it is one of the most popular openings.

Main Lines and Variations

- Indian Defence: 1.d4 Nf6 2.c4 b6

Each of these lines leads to distinct types of positions and requires its own understanding of the resulting pawn structures and piece placements.
Common Mistakes to Avoid
- Allowing White to build an overwhelming center: Hypermodern openings allow White space in the center, but you need to strike back at the right moment. Delaying the counterattack too long can leave you without active play.
