The central tension after 4...d5 is what the Four Knights d3 is all about. White's pawn on c4 stares at your d5 pawn, and Black's e5 pawn faces White's f3 knight. Neither side wants to release the tension without a good reason. Your main idea as Black is straightforward: develop naturally, keep the centre fluid, and be ready to recapture on d5 with a knight if White takes. The open lines that result favour active piece play, and with the king not yet committed on either side, the game can turn sharp very quickly. If White plays timidly, you can seize space in the centre or on the kingside.
The Engine's Vote: Take with the Pawn
FACTS tell us that White's best move here is cxd5, which has been played over 42,000 times — by far the most popular choice. After cxd5 Nxd5 e4 Nf6, White scores 50.9%, barely above half. That tiny edge comes from the space White gains with e4, but Black's knight retreats to f6 with a solid, flexible position. Your plan after this line is simple: complete development, castle, and prepare to counter in the centre. The position remains rich for both sides.
White's Most Common Mistakes
Because this position is so balanced, even small errors can cost White dearly. The database reveals three moves that hurt White significantly. Bg5 is an inaccuracy, losing about 0.6 pawns. It misplaces the bishop early and lets Black chase it or trade on favourable terms. g3 is a full mistake, costing roughly 1.1 pawns — it weakens the kingside dark squares without any immediate benefit. b3 is worse still, losing about 2.1 pawns; it's too slow and allows Black to seize the centre. For you as Black, the message is clear: play solidly and these inaccuracies will hand you an edge. In the drill you'll practise punishing exactly these kinds of over-ambitious or passive moves.
What the Statistics Reveal About Your Chances
The Lichess database of 53,528 games tells a great story for Black. White's win rate across all lines is 49.3%, Black's is 46.3%, and draws are a rare 4.4%. Those numbers mean this opening leads to decisive games — with only 4.4% draws, nearly every game produces a winner. More importantly, look at what happens when White avoids the best move cxd5. Against Bg5, White scores only 45.4%; against g3, 45.6%; against b3, just 39.0%; against e4, a measly 38.8%. Every single sub-optimal move drops White's results below 50%. Your job is to recognise when White has deviated and seize the initiative.

Frequently asked questions
Is the English Four Knights d3 good for Black as a surprise weapon?
Absolutely. With a +0.05 evaluation it's dead level, meaning you are not fighting for equality — you start there. The position is less theoretical than many e4 openings, and the statistics show Black scores 46.3% overall, which is excellent for a sound, offbeat choice.
What is Black's plan after cxd5 Nxd5 e4 Nf6?
Black's knight retreats to f6, and you should continue with natural development: castle, complete your piece setup, and look for central counterplay. Your main idea is to remain flexible and pressure the centre — White's space advantage from e4 is modest, and Black's solid position gives plenty of room to manoeuvre.
How should Black punish White playing g3 in this position?
White's g3 is a mistake worth about 1.1 pawns. Black should respond actively — seize central space and exploit the weakened kingside dark squares. The key is to keep up the pressure; White has spent a tempo on a passive move and you should make them pay. White scores only 45.6% after g3.
Why does b3 lose so badly for White here?
White's b3 drops roughly 2.1 pawns because it does nothing for development or the centre. Black should answer vigorously — seize the centre, gain a lead in development, and exploit White's passivity. The statistics back this up: White scores just 39.0% after b3, the worst result of any common reply.
