Overview

London System, with Bd3 is a specific line in the Flank Openings family (ECO A48), 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 Nf6 2. Nf3 g6 3. Bf4 Bg7 4. e3 d6 5. Bd3, after 9 plies of opening development.

The line refines London System, which traces back to the root opening Queen's Pawn Game.
