The London System in One Lesson

Every board on this page is live. Move the pieces by tapping or dragging, click any move in the lines to see that position, and press ↺ to start again.

1.1 Why the London?

Most players who answer 1.d4 spend their study time on the Queen's Gambit. When you play 1.d4 and 2.♗f4 instead, much of that preparation is useless. Your opponent has to think for themselves from move two, while you play a setup you know by heart.

The London is not a trick. Strong grandmasters, including world champions, use it in top tournaments. It is solid, it is easy to learn, and it leads to positions with clear plans. That combination makes it ideal for a club or rated player who wants to save time on theory and spend it on middlegame skill.

1. One setup against almost everything. d4, ♗f4, e3, ♘f3, c3, ♗d3, ♘bd2 and castling — the same moves against ...d5, ...♘f6, ...e6 and many other replies.
2. Little forced theory. Mistakes in the first ten moves rarely lose the game, so you can play on understanding.
3. Real winning chances. The plans — a knight on e5, a kingside attack, the e4 break — give you something active to do in every game.

1.2 The Setup and the Move Order

The pieces always go to the same squares. Learn this picture first, then we will see how to reach it against each Black defence.

Move order matters. Play 2.♗f4 straight after 1.d4: if you play e3 first, the bishop can no longer reach f4. After ♗f4 the usual order is e3, ♘f3 and c3, then ♗d3 and ♘bd2. Against an early ...c5 the moves c3 and e3 come first, because they support the d4-pawn.

1.3 Three Plans

Almost every London game uses one, two or all three of these ideas:

1. The knight on e5. From e5 the knight attacks f7, c6 and d7 and supports a kingside attack. Often it is backed up by f2–f4, building a wall that Black cannot easily break.
2. The e3–e4 break. When Black's pieces are passive, pushing e4 opens the centre for your well-placed bishops.
3. Queenside pressure with ♕b3. After ...c5, Black's b7-pawn and the d5-pawn can become targets. The queen on b3 is the London player's favourite move against early queen sorties.
