Modern Defense: Averbakh System
Overview
Modern Defense: Averbakh System is a specific line in the Flank Openings family (ECO A42), arising from a recognised theoretical position.
The Flank Openings group covers flank openings — systems that delay the central pawn break and instead develop pieces and pawns on the wings.
Play reaches this position via 1. d4 g6 2. c4 Bg7 3. Nc3 d6 4. e4, after 7 plies of opening development.
The line refines Modern Defense, which traces back to the root opening Queen's Pawn Game.
The line splits into 2 documented sub-systems: Modern Defense: Kotov Variation, Modern Defense: Randspringer Variation.
