Queen's Indian Defence

The Queen's Indian defence is an important defence to 1.d4. It features a fianchetto of Black's QB.

It starts as follows:
1.d4 Nf6
2.c4 e6
3.Nf3 b6
and now 4e3, 4Nc3 and 4g3 are all possible. So is 4.a3, which prepares 5.Nc3 by preventing Black's 5...Bb4. This is the most usual line:

4.g3 Bb7 (4...Ba6 is also played here)
5.Bg2 Be7
6.0-0 0-0
7.Nc3 Ne4
8.Qc2 Nxc3
9.Qxc3
