Queen's Pawn Game: Stonewall Attack with c5 — Playing as White
You've set up the Stonewall Attack with 1.d4 d5 2.e3 Nf6 3.Bd3, and now Black has challenged your centre with 3...c5. You play 4.c4, entering a position that feels like a reversed Queen's Gambit. Stockfish evaluates this at -0.23, a tiny edge for Black — essentially dead level. With 44.5% White wins and 52.3% Black wins across over 6,300 games, the statistics show Black scores slightly better in practice, but there's plenty of play left. Let's see how to handle the critical moment ahead.

After 4.c4, Black has several options, but the engine's top reply is 4...cxd4 (1,859 games in the database). This immediately opens the centre and turns the game into something close to a Queen's Gambit Declined with colours reversed. White's best response is 5.cxd4, meeting the capture with a capture of your own. That leads to 5...exd4 6.e5 dxe5, and Black's knight on f6 must move. You get a space advantage and the bishop pair — a solid setup. The key idea: don't hesitate to give back the pawn to open lines for your pieces. Your light-squared bishop on d3 becomes very active after the centre clears.
What the Statistics Tell Us
The 6,339-game database reveals a clear hierarchy of Black's replies and how you should prepare for each. The most popular move, 4...cxd4, sees White scoring only 43.4% — that's below your overall average of 44.5%, meaning Black handles this reply well. The second-most common is 4...e6 (1,588 games), where White scores a much healthier 47.1% — a reason to be happy if Black builds a solid pawn chain instead of capturing. 4...Nc6 (1,574 games) gives White just 42.8%, while 4...dxc4 (726 games) yields 45.0%. The rarest reasonable move, 4...g6, is a disaster for White at only 36.8% — watch out for this fianchetto setup, which seems to trouble Stonewall players.
The Mistake to Punish: 4...Bg4
One move stands out as a genuine inaccuracy: 4...Bg4. Played in 317 games, this pin of the f3-knight (yet to develop) looks natural but costs Black about half a pawn according to the engine. The best reply is simply 5.cxd5, threatening to win a pawn since the queen protects the d5-pawn and the bishop on g4 is loose. If Black recaptures with 5...Qxd5, you play 6.f3, forcing the bishop to move and gaining a tempo. If instead Black tries 5...Bxf3 6.gxf3, you get the bishop pair and ruined Black's kingside pawns — a fine trade. When you see 4...Bg4 in the drill, punish it immediately.
Your Typical Middlegame Plans
No matter which reply Black chooses, a few themes recur. Your light-squared bishop on d3 points at Black's kingside, often combining with a quick e3-e4 break to open the centre. Your knight can go to f3 (or e2 if the f3-square is taken), and your queen sometimes goes to c2 or b3 to press on the c4- or d5-squares. If Black plays dxc4, you recapture Bxc4 and enjoy a strong bishop pair targeting the kingside. The Stonewall structure (pawns on d4, e3, f4) is flexible here — don't feel locked into it. Many of the best lines involve giving up the d4-pawn to get active piece play.

Frequently asked questions
Is the Stonewall Attack c4 gambit sound for White?
Yes, it's perfectly sound. The engine evaluates 4.c4 at -0.23, essentially dead equal. White's 44.5% win rate in the database is a little below Black's 52.3%, but that's typical for many open positions where Black has equalised. You're not sacrificing anything — just playing a reversed Queen's Gambit.
What is the best move for White after 4...cxd4?
The engine recommends 5.cxd4, keeping the centre open. After 5...exd4 6.e5, Black's knight on f6 must move, and you get active play. This scores 43.4% for White in practice, which is acceptable for a dead-level position.
How should I respond if Black plays 4...Bg4?
That's a mistake you can punish. Play 5.cxd5 immediately, threatening to win a pawn. If Black captures the d5-pawn with the queen, you play f3 to chase the bishop. If Black takes on f3, recapture with the g-pawn and enjoy your bishop pair against Black's broken kingside.
Why does 4...g6 score so poorly for White (36.8%)?
The fianchetto setup is tricky for Stonewall players because Black's bishop on g7 pressures the long diagonal while White's centre is somewhat inflexible. In the drill, you'll need to find active counterplay — often with an early e4 push or a queenside expansion — to avoid being squeezed.
