1.d4 Nf6 2.c4 e6 3.Nf3 b6.The Queen's Indian Defense is a Black opening against 1.d4 where White has played Nf3 early. That matters because White has avoided some Nimzo-Indian pins, and Black answers with ...b6, preparing a queenside fianchetto.
This is a hypermodern opening. Black does not occupy the whole center with pawns. Black develops pieces toward the center, watches e4, and tries to make White's pawn center commit before attacking it.
Train the Queen's Indian if you want a solid but active Black repertoire against queen-pawn players who avoid the Nimzo-Indian.
The bishop on b7
...Bb7, Black puts long-range pressure on the center.The simplest Queen's Indian plan is ...Bb7. The bishop looks down the long diagonal and helps Black fight for e4. White often fianchettoes with g3, builds the center, and tries to use the extra space.
Black's job is to stay flexible. Sometimes the game calls for ...Be7 and castling. Sometimes Black plays ...Bb4+, ...Ne4, or central breaks. The opening rewards remembering structures more than forcing variations.
The ...Ba6 idea
...Ba6 setup challenges White's development and dark-square control.Black can also play ...Ba6, especially against White's kingside fianchetto. The idea is to make White spend time defending or developing the bishop on f1.
This branch is a good reminder that the Queen's Indian is not only a quiet system. Black's pieces can become active early if White develops casually.
