The London setup is a starting point
1.d4 d5 2.Bf4 Nf6 3.e3 e6 4.Nf3 c5 5.c3 Nc6 6.Nbd2.The London System usually places White's pawns on d4, e3, and c3, with the dark-squared bishop outside the chain on f4. Nf3, Nbd2, and Bd3 complete a compact setup that is easy to recognize across several move orders.
That familiar shape is useful, but it does not choose every move for you. Black can attack d4 with ...c5, pressure b2 with ...Qb6, copy the bishop with ...Bf5, or fianchetto with ...g6. Each choice changes White's next job. Train the position where the plan changes, rather than replaying the same setup regardless of Black's moves.
Develop the bishop before playing e3
White plays Bf4 early because e3 will close the c1-h6 diagonal. On f4, the bishop controls e5 and supports the central outpost that appears in many London positions. The rest of the setup then protects d4 and prepares quick kingside development.
Move order still matters. Playing Nf3 too early can allow ...Nh5, while delaying Nf3 may leave Qb3 available against a queen on b6. The course uses both orders. The board should tell you which piece belongs first.
The classical line builds around e5
When Black uses ...c5, ...Nc6, and ...Bd6, White can keep the f4-bishop with Bg3. Exchanging on g3 later may open the h-file, while taking on d6 too soon can help Black develop the queen. The bishop retreat keeps both options available.
The main plan is Ne5. If Black exchanges that knight with ...Bxe5, the d-pawn can recapture on e5, drive the f6-knight away, and open Qh5 against h7. The London System course uses this sequence as its interactive sample line because it connects the setup to a concrete attack.
Early ...Qb6 changes the move order
...Qb6, Black attacks b2 while increasing pressure on d4.An early queen on b6 attacks a pawn that the f4-bishop no longer protects. White should answer that threat before finishing the usual setup. Qb3 can meet the queen directly, and if Black gains space with ...c4, Qc2 keeps the queen safe while watching the center.
This branch is a good test of whether you understand the London or only remember its piece placement. Nf3, Bd3, and castling remain sensible goals, but b2 and the queen route come first. The course also includes the poisoned-pawn line where a greedy ...Qxb2 gives White time to chase the queen with Nc3, Nb5, and Rb1.
A mirrored bishop calls for c4
...Bf5, White has switched from c3 to c4.Black can copy Bf4 with ...Bf5. Building the standard c3 pyramid gives Black an easy version of the same structure, so White should challenge d5 with c4 instead. The position now resembles a Queen's Gambit more than a quiet London.
Qb3 adds pressure to b7 and d5. If the queens come off on b3, axb3 gives White an open a-file and a queenside pawn majority that can gain space with b4. The visual cue is simple: when both bishops stand outside their pawn chains, change the pawn structure before Black completes an effortless mirror.
The Indian setup requires a larger center
...g6 and ...Bg7, Nc3 and e4 give White a larger center.Black's kingside fianchetto changes the pressure on the dark squares. A routine Bd3 can run into ...g6, so White often develops that bishop to e2 or switches to Nc3 and e4. The latter setup uses the London bishop to support a broad center instead of a fixed pawn pyramid.
After Nc3 and e4, White may castle queenside and attack with f3 and h4. An immediate e5 can also become tactical if Black is careless with the queen and back rank. These sharper lines belong to the same family, but they must be trained separately from the classical London. The common feature is Bf4 before e3, not an obligation to place every other piece on one square.
What to train first
Begin with the interactive classical sample in the London System course. It teaches the basic setup, the Bg3 retreat, the e5 outpost, and the Qh5 attack in one line.
- Add the
...Qb6and poisoned-pawn lines when pressure on b2 disrupts your move order. - Study the mirror line when you keep reaching equal structures with no plan.
- Train the
...g6branches separately so Nc3, e4, and Be2 come to mind instead of an automatic Bd3. - Use the
...Bg4and...Nh5lines to learn when the f4-bishop should retreat, trade, or allow the h-file to open.
The London becomes easier to remember once each black setup has one visible cue and one answer. Keep the basic structure, then change the plan when the board gives you a reason.
