Main Variations

The Ideal Move Order for White

Before looking at the variations, here is the typical development scheme for the London System:

d4 → Bf4 → e3 → Nf3 → Nbd2 → c3 → Bd3

The order may vary, but the principle is always the same: Bf4 must come out BEFORE e3, otherwise the bishop remains blocked.

Variation 1: The Main Line (against ...d5 ...c5)

This is the most common position. Black plays a classical structure with ...d5 and ...c5 to challenge the center.

Typical continuation:

d4 Nf6 Bf4 d5 e3 c5 c3 Nc6 Nbd2 e6 Ngf3 Bd6 Bg3 O-O Bd3

Why this position is strong for White:

• The Bd3 aims at h7, creating potential threats against Black's kingside
• Bg3 is well placed on the long diagonal, and if Black exchanges with ...Bxg3, hxg3 opens the h-file
• The knight on d2 can go to e4 to attack the Bd6
• After O-O, White can play Re1 and prepare e4

The key question for Black: what to do with the Bd6?

• If ...Bxg3, hxg3 gives White the h-file and a good structure
• If the bishop stays on d6, Ne4 will be annoying

Variation 2: Against the ...Bd6 System with Exchange

When Black plays ...Bd6 to copy White's structure, a strong idea is the exchange:

d4 Nf6 Bf4 d5 e3 e6 Nf3 c5 c3 Nc6 Nbd2 Bd6 Bxd6 Qxd6

After the exchange, White plays Bd3, O-O, and aims for the e4 push. Black has lost their dark-squared bishop, which weakens the dark squares around their king.

Variation 3: The Ne5 Plan

One of the most powerful ideas in the London System is the move Ne5, installing a dominant knight in the center:

d4 Nf6 Bf4 d5 e3 e6 Nd2 c5 c3 Nc6 Ngf3 Bd6 Bg3 O-O Bd3 Qe7 Ne5

The knight on e5 is extremely strong:

• It cannot be easily chased away (no Black pawn on f6)
• It controls key squares: c6, d7, f7
• It prepares f4 to reinforce central control
• If ...Nxe5, dxe5 pushes back the Nf6 and opens the d-file

Variation 4: Against ...Qb6 (attack on b2)

A frequent trap: Black plays ...Qb6 to attack b2. Don't panic!

d4 Nf6 Bf4 d5 e3 c5 Nf3 Nc6 c3 Qb6 Qb3 c4 Qc2

Why Qc2 is the right move:

• The queen on c2 aims at h7, combined with Bd3 it creates a dangerous battery
• Is the b2 pawn sacrificed? No! After ...Qxb2?? Nbd2, Black's queen is trapped
• White prepares Bd3, O-O, and a natural attack

Variation 5: Against the King's Indian (...g6 ...Bg7)

Against Black's fianchetto, White plays differently:

d4 Nf6 Bf4 g6 Nf3 Bg7 e3 d6 Be2 O-O O-O Nbd7 h3 c5

Specific ideas:

• Bh6: Exchange Black's good bishop (the Bg7 is their best piece!)
• d5: Close the center to neutralize the Bg7
• c4: Gain space on the queenside
• Be2 (instead of Bd3) is preferred here because there is no target on h7

Strategic Plans and Key Ideas

White's Main Plan: The Bd3 + Qc2 Battery

The most classic attacking plan in the London System is the Bd3 + Qc2 battery aiming at h7:

After Qc2, White directly threatens h7. Black must play ...g6 (weakening the dark squares) or ...h6 (creating a target). In both cases, White gets attacking chances.

The hxg3 Idea: Opening the h-File

When Black plays ...Bxg3, always recapture with hxg3 (not fxg3):

• The h-file opens for your rook
• The g3 and g2 pawns form a solid structure
• The h1 rook (or Rh1 after castling) enters the attack directly

This is one of the most dangerous positions in the London System for Black.

For Black: How to Counter the London?

Plan 1: Early ...c5

The ...c5 break is the best reaction. It challenges the d4 pawn and opens lines for counterplay.

Plan 2: ...Qb6 to target b2

As seen in Variation 4, ...Qb6 is a popular idea but White has Qc2 as a good response.

Plan 3: ...Bf5 to exchange bishops

If Black manages to exchange their bad light-squared bishop (via ...Bf5), the position equalizes easily. White must prevent this exchange with Nh4 or by retreating the Bg3.

Common Mistakes to Avoid

Mistake 1: Playing e3 BEFORE Bf4

Problem: If you play e3 before developing the bishop to f4, the bishop remains blocked behind your own pawns. You will no longer be able to play Bf4 and will lose the main plan of the London System.

Solution: Always play Bf4 before e3. The recommended order is: d4, Bf4, e3.

Mistake 2: Recapturing fxg3 instead of hxg3

Problem: When Black exchanges ...Bxg3, recapturing fxg3 weakens your pawn structure and opens no useful file.

Solution: Always recapture hxg3. This opens the h-file for your rook and creates attacking chances against Black's king.

Mistake 3: Letting Black exchange the light-squared bishops

Problem: If Black plays ...Bf5 and exchanges your Bd3, they eliminate your main attacking piece and the position flattens out.

Solution: Prevent ...Bf5 with Nh4 or Ne5. Keep the Bd3 on the board -- it is your best attacking piece.

Mistake 4: Ignoring ...c5

Problem: Black plays ...c5 and you do not react. If you allow ...cxd4 exd4, your d4 pawn can become isolated.

Solution: Play c3 to support the center. After ...cxd4 cxd4, your center remains solid and you have a semi-open c-file for your rook.
