Anti-London System: Complete Guide
What is the Anti-London System?
The Anti-London is a complete Black answer to the London System, the 1. d4 and 2. Bf4 setup that has become the most common queen-pawn opening at club level. Instead of drifting into a slow, symmetrical game on White’s terms, Black hits the base of the center at once with 1. d4 d5 2. Bf4 c5, then follows with ...Nc6 and ...Qb6. Because White’s dark-squared bishop has already left c1 for f4, the b2 pawn is loose and the queen on b6 leans on it from the first moves. It is a system, not a memory test: the same ...c5, ...Nc6, ...Qb6 and ...Nh5 ideas recur against everything White tries, so below 1600 it turns a quiet, comfortable White opening into a fight where Black is the one asking questions.
How to reach it
Every line starts 1. d4 d5 2. Bf4 c5, meeting the London bishop with an immediate strike on d4. From there White’s third move splits sharply at club level: close to half play the solid 3. e3, about one in five support the center with 3. c3, roughly one in six develop 3. Nf3, and around one in eight grab the pawn with 3. dxc5. The knight jump 3. Nc3 and the rare 3. e4 gambit round out the field. This trainer gives one coherent recipe against each: the ...Nc6, ...Qb6 and ...Bf5 wall against quiet play, the ...Nh5 bishop hunt to trade off White’s good bishop, the ...e5 fork when the knight recaptures on d4, and a queen trade or a clean pawn grab when White surrenders the center.
Pros & cons
Strengths
- One repeatable plan, ...c5, ...Nc6, ...Qb6 and the ...Nh5 bishop hunt, works against nearly every London move order, so study time goes into ideas instead of theory.
- You take the initiative from move two: ...c5 hits d4 and ...Qb6 immediately pressures the b2 pawn the London bishop left undefended.
- Built-in free wins: when White recaptures on d4 with the knight, ...e5 forks the knight and the f4 bishop; when White jumps a knight to b5, ...Qa5+ pins and wins it.
- The bishop hunt with ...Nh5 trades off White’s prized London bishop for a knight and hands Black the bishop pair.
- A concrete answer to the greedy tries: the pawn-grabbing 3. dxc5 is rounded up cleanly, and 3. Qxd5 or 3. e4 gambits are refuted by force.
Drawbacks
- The ...c5 counter is a chosen weapon, not White’s problem to force; you have to know it and play it on purpose rather than drift into a symmetrical setup.
- When you grab the b2 pawn with the queen you must come straight home; getting greedy with the a1 rook can trap the queen in the corner.
- Some lines leave White with an isolated d-pawn where you play for a small, patient edge rather than a knockout.
- The sharpest tries, the knight-recapture forks and the ...Qa5+ pins, reward accurate move orders, so the free wins have to be memorized in the right sequence.
Main variations
The c5 Wall against 3. e3
1. d4 d5 2. Bf4 c5 3. e3 Nc6 4. Nf3 Nf6 5. Nd2 Bf5 6. c3 Qb6
White’s most common choice is the solid 3. e3. Black builds the standard wall with ...Nc6, ...Nf6 and ...Bf5, then plants the queen on b6 to lean on b2. The position is balanced and easy to play, White’s bishop on f4 bites on granite, and Black already has the more natural plan of ...c4 or a central break.
The Bishop Hunt with ...Nh5
1. d4 d5 2. Bf4 c5 3. e3 Nc6 4. Nf3 Nf6 5. c3 Nh5 6. Bg3 Nxg3 7. hxg3 Qb6
The signature idea of the whole system: ...Nh5 chases the London bishop, and after Bg3 the trade ...Nxg3 hands Black the bishop pair and doubles White’s g-pawns. If White tries to keep the bishop with Bg5, ...h6, ...g5 and ...g4 chase it down anyway. This is the fun, farmable heart of the Anti-London.
Free Pawns and Forks against 3. Nf3
1. d4 d5 2. Bf4 c5 3. Nf3 cxd4 4. Nxd4 Nd7 5. e3 e5
When White recaptures on d4 with the knight and then plays the natural-looking 5. e3, Black strikes with 5...e5, forking the knight on d4 and the bishop on f4. White cannot save both pieces and drops material by force. It is the cleanest free win in the course and the game the trainer opens with.
The dxc5 Center Grab
1. d4 d5 2. Bf4 c5 3. dxc5 Nc6 4. e3 e5 5. Bg3 Bxc5
If White grabs the pawn with 3. dxc5, Black does not hurry to take it back. ...Nc6 and ...e5 build a broad center, ...Bxc5 regains the pawn with tempo, and Black emerges with more space and easier development. When White clings to the extra pawn with a3 and b4, the course shows how to round it up anyway.
The Queen Trade against 3. c3
1. d4 d5 2. Bf4 c5 3. c3 Qb6 4. Qb3 Qxb3 5. axb3 cxd4
Against 3. c3 Black hits b2 at once with ...Qb6. White’s only real defense is to offer the queen trade with Qb3, and after ...Qxb3 axb3 White is left with doubled b-pawns and an open a-file for Black. It is a pleasant endgame edge with no risk, ideal when you want a clean, low-theory game.
Playing against the Anti-London System
Facing the Anti-London with White, the mistake is to play on autopilot: the London bishop on f4 leaves b2 loose, so a quick ...Qb6 always pokes at it, and drifting lets Black seize the initiative for free. Do not grab the c5 pawn and try to hold it, because Black regains it with ...Nc6, ...e5 and ...Bxc5 while gaining time on your pieces. When you recapture on d4 with the knight, watch for the ...e5 fork before you play a routine e3. The soundest tries keep the bishop safe from the ...Nh5 hunt, meet ...Qb6 with Qb3 or b3 rather than losing b2, and aim for the small structural pluses of an Exchange or Nbd2 setup instead of forcing matters.
Plans
For White
Keep the London solid and do not let the f4 bishop become a target. Support the center with e3 and c3, answer ...Qb6 with Qb3 or b3 so the b2 pawn is never simply lost, and when a knight sits on d4 remember that a careless e3 walks into ...e5. If you want the pawn from 3. dxc5, be ready to give it back for development rather than clinging to it. Aim for a quiet structural edge, an Exchange on d5 or a Nbd2 setup, not a forcing fight where Black’s ...c5 and ...Qb6 have the initiative.
For Black
Play the system, not a memorized tree. Meet 2. Bf4 with ...c5, develop ...Nc6 and put the queen on b6 to pressure b2. Hunt the London bishop with ...Nh5 when it lands on f4, and take the free wins when they appear: ...e5 forks the knight and bishop after Nxd4, and ...Qa5+ pins and wins a knight that jumps to b5. Against 3. dxc5 build the center with ...e5 and ...Bxc5, and against 3. c3 trade queens on b3 for a comfortable endgame. When you grab the b2 pawn, retreat the queen and stay a healthy pawn up.
History
The London System, White’s 1. d4 and 2. Bf4 setup, grew from a 1922 London tournament into one of the most popular openings in modern club and online play, prized for reaching the same comfortable position against almost anything. Black’s answer with an early ...c5 is the practical response that databases of millions of games point to: strike the base of White’s center before the e3 and c3 pyramid is complete, and use the fact that the c1-bishop has left home to hit b2. It sits in the Queen’s Pawn family under ECO code D02, closely related to the Queen’s Gambit and Slav structures, and has become the standard club recipe for players who want to meet the London head on rather than mirror it.
Frequently asked questions
- What is the best way to play against the London System as Black?
- The most active answer is an early ...c5. After 1. d4 d5 2. Bf4 c5 Black hits the base of White’s center at once, develops ...Nc6 and ...Qb6 to pressure the b2 pawn the London bishop left loose, and reaches the same active plans against nearly every White setup.
- Is the Anti-London good for beginners?
- Yes. It is a system, so you learn a handful of ideas, ...c5, ...Nc6, ...Qb6 and the ...Nh5 bishop hunt, instead of long forcing lines, and the same plans work against almost everything White plays. It also has clear free-win traps that are satisfying to land below 1600.
- Does 2...c5 really refute the London?
- It does not refute a sound opening, but it fully equalizes and takes the initiative. ...c5 pressures d4, ...Qb6 targets the loose b2 pawn, and White’s comfortable autopilot setup becomes a real fight in which Black often has the easier game at club level.
- What are the main free wins in the Anti-London?
- Two recur often. When White recaptures on d4 with the knight and plays e3, ...e5 forks the knight and the f4 bishop and wins material. When a white knight jumps to b5, ...Qa5+ pins and wins it. The greedy 3. Qxd5 and 3. e4 gambit tries are also refuted by force.
