Solid and reliable — same setup against anything
The main line
1.d4 d5 2.Nf3 Nf6 3.Bf4 e6 4.e3 Bd6 5.Bg3 O-O 6.Bd3 Bxg3 7.hxg3 c5 8.c3 Nc6 9.Nbd2 Qc7
Strategic ideas
- Build the same setup (Nf3, d4, Bf4, e3, Bd3) regardless of Black's replies
- Place the bishop outside the pawn chain on f4 before playing e3
- Time the e4 central break when Black's pieces are committed
- Advance against queenside castlers with a direct kingside attack
- Use the London's predictability as a psychological advantage in blitz and rapid
Key themes
- Solid — The London's set-up is virtually unbreakable in the opening — White never faces an immediate crisis
- Positional — White builds up slowly and methodically, relying on piece coordination rather than forcing lines
- Flexible — The same setup works against virtually any Black response, requiring minimal preparation
Typical plans
White plays Nf3, d4, Bf4, e3, and Bd3 regardless of what Black does, building a reliable and theory-free setup. The long-term plan is to advance e4 at the right moment to seize central space and activate all pieces. Against queenside castlers, White can launch a direct kingside attack. The London's main strength is its predictability and resistance to preparation.
