Queen's Indian DefenseEdit

4. g3Edit

With this move, White decides to challenge the h1-a8 diagonal immediately and fianchetto his own light-squared bishop to counter black's.

Black can now play:

  • 4...Bb7, a standard developing move. White can then respond with Bg2 and Nc3.
  • 4...Ba6, attacking the c-pawn. This is a bit of a nuisance for white, who cannot comfortably defend the pawn with the natural e2-e3 because the bishop is already committed to g2.
  • 4...Bb4+, echoing the Bogo-Indian and Nimzo-Indian defences. White can interpose with the bishop or knight.
