London System
Overview
London System is a named branch in the Flank Openings group of chess theory, classified under ECO A48.

The line arises from 8 plies — specifically the moves 1. d4 Nf6 2. Nf3 g6 3. Bf4 Bg7 4. e3 d6.
In the opening tree, this line branches off from London System, part of the broader Queen's Pawn Game system.

Together the deeper variations number 4 across the full subtree.
Use the board to walk through every move, check how the position has scored on Lichess, or take it head-to-head against Stockfish.
