The Queen's Indian Defence: 1.d4 Nf6 2.c4... 4.g3 arises after 1.d4 Nf6 2.c4 e6 3.Nf3 b6 4.g3 and falls under ECO code E15. By playing 4.g3, White prepares to fianchetto the light-squared bishop, directly contesting the h1-a8 diagonal where Black's own bishop aims to exert influence. While the Modern Main Line has since emerged as an important alternative, this classical fianchetto approach remains a principled way for White to fight for control of the long diagonal. With 911,505 Lichess games across all rating levels, it is a well-established opening choice.
