Queen's Indian Defense

The Queen's Indian Defense (1.d4 Nf6 2.c4 e6 3.Nf3 b6) is a solid and flexible defense where Black fianchettoes the queen's bishop to control the e4 square. It's the main alternative to the Nimzo-Indian.

About the Queen's Indian Defense

The Queen's Indian arises when White avoids 3.Nc3, preventing the Nimzo-Indian. Black responds with 3...b6, developing the bishop to b7 to control the light squares, especially e4. The main lines include the Classical (4.g3), the Petrosian System (4.a3), and the Kasparov-Indian (4.Nc3 Bb7 5.Bg5). The QID leads to strategic, positional battles and has been a staple of top-level chess.
