The hardest thing about most openings is that you have to react. Your opponent chooses a defence, you try to remember the right answer, and one slip in the move-order can drop you into a position you have never seen. The London System removes that anxiety almost entirely. You decide, before the game starts, where every one of your pieces is going — d4, Bf4, e3, Bd3, c3, Nbd2, castle — and you play that setup against nearly everything Black tries. This article is about how to make that setup do more than merely survive.
This is a tutorial: the ideas and the plans you need at the board. For the encyclopedia reference — the move-orders, the ECO codes, the history — see the entry on the London System. Here we care about why the moves are played, and where the “just develop” advice stops being enough.
The idea
The London is a system opening. Instead of a forcing line, it is a formation: the dark-squared bishop comes out to f4 before you play e3, so it never gets buried behind its own pawns — the mistake that ruins the Queen’s Gambit Declined bishop. Behind it you build a small triangle of pawns on c3, d4 and e3, put the other bishop on the active d3-square aiming at Black’s king, and castle short.
Because you are not trying to refute Black’s opening, you rarely get an advantage out of the opening by force. What you get is a sound, familiar middlegame in which you know the plans and your opponent, very often, is improvising. At club level that is worth more than any half-point of theory. At the top level, players from Gata Kamsky to Magnus Carlsen and Gukesh Dommaraju use exactly that logic — the London as a way to reach a real game while dodging an afternoon of memorised preparation.
The setup, move by move
A typical move-order against 1…d5 runs 1.d4 d5 2.Nf3 Nf6 3.Bf4 e6 4.e3 c5 5.c3 Nc6 6.Nbd2 Bd6 7.Bg3 0-0 8.Bd3. Notice three details that separate a good London from a lifeless one:
- Bishop out on move three. Playing Bf4 before e3 is the whole point. Reverse the order and you have a passive Colle, not a London.
- Meet …Nh5 with Bg3, and recapture with the h-pawn. Black’s most annoying idea is to trade your good bishop. When …Nh5 comes, retreat to g3; if he takes, hxg3 opens the h-file straight at his king — a gift, not a concession. A quiet early h3 often prepares exactly this.
- Bishop to d3, not e2. The light-squared bishop belongs on the b1-h7 diagonal, pointing at h7, because that is where your attack will come from.
Black’s main tries
There are only a few set-ups you must actually understand.
The classical …d5 with …c5 and …Qb6. This is the critical test. Black strikes at the base of your triangle with …c5 and then adds …Qb6, hitting both d4 and the b2-pawn. Do not panic and play passively. The standard answers are Qb3 (offering to trade queens and defuse the attack), Qc1 or Qc2 keeping pieces on, or — if you have looked at it — allowing …Qxb2 and trapping the greedy queen with Nd2-c4-a3 ideas. This is the one line where “play your setup” is not enough; spend your study time here.
The King’s Indian …g6. When Black fianchettoes, you are comfortable. His bishop bites on your d4-granite, your f4-bishop is unopposed, and a plan of h3, Be2 or Bd3, 0-0 and later Ne5 gives an easy game.
The …Bf5 neutraliser. A well-schooled Black develops his own light-squared bishop to f5 before you can trade it, matching your best minor piece. Meet it with c4 and Qb3, pressuring b7 and d5 and asking his bishop to justify leaving the queenside.
Key plans
Whatever Black chooses, three plans recur — and knowing which one the position calls for is the real skill of a London player.
The first is the knight to e5. This is the opening’s signature outpost. Manoeuvre Nbd2-f3 or play the direct Ne5, and back it up with f4 if Black tries to challenge it. From e5 the knight supports a kingside attack and cramps Black’s whole position. Often the follow-up is f4, Rf3 and Rh3, swinging the rook to the h-file.
The second is the kingside pawn storm. When Black castles into a fianchetto, the thematic plan is h4 and h5, opening a file against his king while your bishops on f4 and d3 point the same way. Because your centre is solid and closed, Black cannot easily strike back in the middle while you attack on the wing — the strategic licence that makes the storm sound.
The third is the quiet queenside squeeze, the Capablanca-style London. Trade the central pawns, plant the knight on e5, and press on the half-open c-file, converting small structural advantages in an endgame. Not every London is an attack; some are won by simply having the better pieces.
How to start playing it
You can play your first London game today. Learn the seven setup moves, promise yourself the bishop comes to f4 before e3, and put the light bishop on d3. Then, over your next handful of games, study only the three switch-off moments: the …Qb6 hit on b2, the trade of your f4-bishop, and the choice between the Ne5 plan and the h4-h5 attack. That is a fraction of the theory a sharp 1.e4 opening demands, and it is why the London is the fastest sound opening to learn well.
Its reputation was once “solid but toothless.” That is a half-truth: the London is solid, and it is toothless only in the hands of a player who reaches the setup and then stops thinking. Reach the setup and keep thinking — pick the right one of the three plans — and it is one of the most practical winning weapons in chess.
