Start with the move order, then use the plans, variations, traps, and training workflow below to turn London System into a repertoire you can review with active recall and spaced repetition in ChessFlare.
The London System starts with 1.d4 d5 2.Bf4 or 1.d4 Nf6 2.Bf4. It is a practical system opening for White and belongs in a repertoire when you want positions that are solid, repeatable, and plan-based.
If you searched for london system chess opening, the short answer is this: White builds around d4, Bf4, e3, Nf3, c3, and Bd3, then adjusts to Black's pawn structure instead of memorizing a forcing main line. The real improvement comes when you connect the first moves to the plans, the common counters, and a repeatable training workflow instead of only reading a move list.
Quick answer: what is the London System?
The London System is an opening for White. Its starting move order is 1.d4 d5 2.Bf4 or 1.d4 Nf6 2.Bf4, but the name alone is not enough to play it well. You need to know the pawn structure, the typical piece squares, the main variations, and the mistakes that appear in real games.
It is best for players who want a stable White repertoire with recurring setups and less early theory. The main thing to avoid is autopilot moves, ignoring ...c5 and ...Qb6, and forcing the same setup against every Black structure.
Pros and cons
Strength
Risk
Clear first move order: 1.d4 d5 2.Bf4 or 1.d4 Nf6 2.Bf4
Move-order details still matter
Recurring plans you can train with active recall
Memorized moves fail when the structure changes
Useful for building a focused White repertoire
Opponents can choose side lines if you do not prepare them
Easy to review as separate opening trainer branches
Passive or automatic play gives away the opening's value
How to reach the starting position
The core move order is 1.d4 d5 2.Bf4 or 1.d4 Nf6 2.Bf4. Add it to your repertoire as the root branch first, then create child branches for the most common replies. This keeps the opening searchable, trainable, and easier to maintain when your repertoire grows.
Do not start by memorizing twenty moves. Start with the first critical decision, then add the variation where the plan changes. That is how you turn an opening article into something you can actually play.
Main plans for White
Develop Bf4 early and support the center with e3 and c3 when appropriate.
Watch for Black's ...c5 and ...Qb6 counterplay.
Use Ne5, h3, and kingside pressure only when the structure supports it.
Adjust against fianchetto and early ...c5 setups rather than playing by habit.
These plans matter more than the name of the variation. When you review the opening, ask what pawn break you want, which piece is badly placed, and what your opponent is threatening next.
The standard setup with stable development and clear plans.
London vs ...Nf6 and ...g6
1.d4 Nf6 2.Bf4 g6
Black fianchettoes, so White must decide how much central space to claim.
London vs ...c5
1.d4 d5 2.Bf4 c5
One of Black's most important counters; White must handle central tension correctly.
London vs ...Qb6
1.d4 d5 2.Bf4 Nf6 3.e3 c5 4.c3 Qb6
A practical test of White's b2 pawn and move-order discipline.
Jobava-style ideas
1.d4 Nf6 2.Nc3 d5 3.Bf4
A related aggressive setup, but it should be trained as a separate branch.
How to play against the London System
Against the London, Black should challenge the center, use ...c5, watch b2 pressure, and avoid letting White get the full setup without questions.
This matters because players do not only need the first moves. They also need to know how to counter the opening, where the trap appears, and whether the structure fits their level.
Common traps and tactical ideas
The London looks simple, but many players lose time by moving the bishop twice, pushing e4 too early, or missing tactics on b2 and h7.
Traps are useful only when they teach the structure. Add them as short ChessFlare training branches, then mark the key position where the tactic appears. That way you remember the trigger, not just the final tactic.
Common mistakes
Playing the same seven moves against every Black setup.
Ignoring central tension after ...c5.
Treating the London as a way to avoid thinking.
If one of these mistakes appears in your games, add that exact position to your repertoire review. Opening study works better when the page, the drill, and your real mistakes share the same position.
Use these pages to connect neighboring structures, defenses, transpositions, and tactical families instead of studying every opening as an isolated article.
Final verdict
The London System is worth learning if you want solid, repeatable, and plan-based positions and you are ready to train the critical branches instead of stopping after the first move order. Start with the quick answer, add the main variations, then drill the positions until you can recall the plan without looking at the article.
