Summary
The Indian Game Mainlines arises after 1.d4 Nf6 2.c4 and falls under ECO code A50. 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.
- Black lets White build a broad pawn center on purpose, planning to undermine and eventually demolish it with piece pressure and pawn breaks.
- The move order keeps Black flexible: depending on White's setup, Black can steer into the Nimzo-Indian, King's Indian, Queen's Indian or Grunfeld.
- Each branch has its own flavor, from the Queen's Indian's solidity favored by Karpov to the counterattacking King's Indian beloved by Fischer and Kasparov.
History and Notable Players
It arises from the Queen's Pawn Systems (1...d5). Among the most prolific practitioners on the White side are Ivan Farago (1129 games), Aleksey Dreev (995 games), Svetozar Gligoric (884 games). On the Black side, notable exponents include Viktor Korchnoi (704 games), Wolfgang Uhlmann (569 games), Jan H Timman (559 games).
After 1.d4 Nf6 2.c4 the great Indian defenses branch out: Nimzowitsch championed his Nimzo-Indian from 1913, Grunfeld unveiled his counter in 1922, and the hypermoderns promoted them all in the 1920s. Full respectability came only in the late 1940s, when Soviet players proved the systems sound.
Named after: The 'Indian' label traces to Moheschunder Bannerjee, an Indian player whose fianchetto systems against John Cochrane inspired the name, recorded from 1884.
Notable players: Aron Nimzowitsch, Bobby Fischer, Garry Kasparov, Anatoly Karpov

Main Lines and Variations
After 1.d4 Nf6 2.c4, the main continuations include:
- Old Indian
- King's Indian
- Budapest Gambit
- Nimzo/QID
- Queen's Indian Accelerated
- Benoni Defense (2.c4 c5)
- Grünfeld
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.
