London System

Setup moves: 1.d4 d5 2.Nf3 Nf6 3.Bf4 e6 4.e3 Bd6 5.Bg3

The London System is a resilient, low-theory repertoire where White aims for a harmonious development with the dark-squared bishop outside the pawn chain. Typical pawn structure includes pawns on d4, e3, c3, and often h3 to secure the bishop.

  • Easy development and a safe king.
  • Works against a variety of setups including King's Indian and Queen's Gambit Declined.
  • Plans revolve around e4 breaks or kingside expansions with Ne5, f4, and Qf3.
