One of the Queen's Pawn Side Defences, the
Queen's Indian is Black's major response to 3.Kt-KB3,
and as such is regarded as a sister defence to the
Nimzo-Indian (where White's 3.Kt-QB3
is met by a 3..B-Kt5 pin). |
After setting an Indian KKt, Black pushes
3..P-QKt3(b6) (move 3b,
left), preparing to fianchetto his
Queen's Bishop in order to strike back at White's
K4(e4) square and so prevent an enlarged White pawn centre.
Developed by the "hypermodern" school, it was
regarded as safe and solid for most of the 20th Century until White's
adoption of new ideas in recent years to try and exploit his apparent
spatial advantage in better ways.

In the main "classical" line White adopts a king's-side fianchetto (the
general best response to a Black Q-side Indian bishop), but the
alternative sharp and aggressive Petrosian System
has equal popularity. |
