The Queen's Indian Defense arises after 1.d4 Nf6 2.c4 e6 3.Nf3 b6 and falls under ECO code E12. A well-established and relatively modern system, the Queen's Indian sees Black rapidly activate the queenside bishop, which can be fianchettoed to b7 to fight for control of the long diagonal or deployed to a6 to challenge White's c-pawn directly. The opening has been a regular feature in the repertoires of many elite players, including former world champions Anatoly Karpov and Viswanathan Anand. With 2.2 million Lichess games across all rating levels, it is a well-established opening choice.

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.
