Queen's Indian Defense: Classical Variation
Overview
Queen's Indian Defense: Classical Variation is a specific line in the Indian Defenses family (ECO E17), arising from a recognised theoretical position.
The Indian Defenses group covers Indian defences — hypermodern lines where Black challenges the centre with pieces rather than pawns.
It begins with 11 plies and takes 1. d4 Nf6 2. c4 e6 3. Nf3 b6 4. g3 Bb7 5. Bg2 Be7 6. O-O to reach the canonical position.
The line refines Queen's Indian Defense: Traditional Variation, which traces back to the root opening Indian Defense: Anti-Nimzo-Indian.
The line splits into 5 documented sub-systems: Polugaevsky Gambit, Taimanov Gambit, Traditional Variation, and others.
