How to Play the Queen's Pawn Game: Accelerated London System, Steinitz Countergambit, and 

By playing 3.e4, you're offering a pawn to open lines and seize space in the centre. The idea is straightforward: if Black captures on e4, you can reply d5 — blocking Black's light-squared bishop and gaining a strong central pawn chain. Your bishop on f4 already eyes the queenside, and your pieces will develop quickly. The engine evaluates this position at -0.28, a small edge for Black. That means you're marginally worse, but the position is far from losing — it's dynamic and imbalanced. You're betting that your activity and attacking chances outweigh the missing pawn. If Black doesn't know how to handle the sudden aggression, you can easily take over the game.

Stockfish's top choice for Black is 3...dxe4, accepting the gambit. This move has been played in 6,864 games — over half the database. The engine's suggested continuation is dxe4 d5 g6 Nc3. After you recapture with d5, you block Black's bishop, and your knight on c3 will target the e4 pawn. From this line, White scores 48.1% — a slight dip below your overall average, but still fully playable. The key here is not to rush. Develop naturally, put pressure on the centre, and look for chances against Black's kingside once they commit to ...g6 and ...Bg7. The pawn sacrifice gives you long-term piece play.

Many Black players avoid the gambit, and that's where your winning chances jump. Here are the three most common inaccuracies and mistakes in this position: 3...e6 is an inaccuracy that loses roughly 0.8 pawns of advantage. It's been played in 1,897 games, and White scores a solid 49.3% from there. 3...cxd4 is also an inaccuracy, losing about 0.6 pawns — played 1,883 times, with White scoring 51.0%. The real gift is 3...c4, which is a full mistake costing about 2.2 pawns. In those 126 games, White wins 54.0% of the time. Whenever Black doesn't capture on e4, you should grab the centre and develop with tempo. Your pawn on e4 gives you space, and Black's passive setup will be hard to untangle.

Across all 13,505 games from this position, the results are remarkably balanced: White wins 49.4%, draws 3.2%, and Black wins 47.5%. That draw rate is extremely low — this isn't a quiet, manoeuvring line. The Accelerated London with 3.e4 leads to decisive games where both sides have chances. Other common Black replies include 3...Nc6 (1,872 games, White scores 49.0%) and 3...Nf6 (466 games, White scores 56.7% — your best statistical result). When Black plays ...Nf6, they're ignoring the centre tension, and you can often come out ahead with accurate play. The overall picture is clear: learn the key ideas after 3...dxe4, stay alert for Black's mistakes, and you'll score well above the 50% mark.
