How to Play the French Defense: Exchange Variation with 4.c4
Most French Defense players expect you to exchange on d5 and then defend a passive pawn chain. In the Exchange Variation: Qxd5 line, you do the opposite — you give back the pawn immediately with 4.c4 and chase the black queen around the board while building a powerful centre. The statistics across nearly 181,000 games show this is a reliable weapon: White scores over 55% from this position, and the engine gives your position a clear advantage. The key is knowing which queen moves are harmless and which one you should actually prepare for. Use the interactive drill below to practise meeting each reply until you can play 4.c4 with confidence.

When Black plays 3...Qxd5, they are asking you to defend your e-pawn or retreat. Instead, 4.c4 attacks the queen and fights for central space at the same time. You are offering Black a choice: retreat the queen to a square where it will be vulnerable to your pieces, or check you from a flank — but those checks come at a cost. Statistically, White wins 55.7% of the time from here, draws only 3.8%, and loses 40.5%. That means in practical play, you win more than you lose by a solid margin, and the 4.c4 advance is the reason why. You are fighting for full-centre control while developing with tempo.
The Engine's Best Move: Qd8
Stockfish evaluates this position at +0.76, a clear plus for White. That means you are clearly better here — and the engine's top choice for Black is Qd8, returning the queen to its home square. After Qd8, the recommended line runs Nf3 c5 Nc3. Notice what happens: Black concedes the centre with ...c5, trying to challenge your d4-pawn, but you have already developed two knights and control the key squares. Your plan is simple — finish development, keep the d4-pawn secure, and enjoy the extra space. Black scores just 45.5% from this position (combined wins and draws), so you can expect to outplay them in the middlegame.
Punish Black's Impatient Queen Moves
Many Black players cannot resist checking your king. Two common mistakes stand out in the database: Qe4+ (42,334 games) and Qa5+ (25,513 games). Both are inaccuracies. Qe4+ loses about 0.6 pawns of advantage compared to Qd8, while Qa5+ is even worse, losing around 0.8 pawns. Why? After Qe4+ you simply block with Be3 or Nc3, and Black's queen has to move again, costing tempo. Against Qa5+, Nc3 or Bd2 followed by Nf3 leaves Black's queen awkwardly placed on a5. White scores 58.7% against Qa5+ — your best winning percentage of any major reply. If your opponent plays one of these checks, stay calm, block with a developing move, and let them waste time.
What About the Other Replies?
You will also see Bb4+ (20,271 games) and the quieter Qd7 (4,543 games) or Qd6 (1,994 games). Against Bb4+, White scores 53.2% — solid but unspectacular. The check is annoying, but after Bd2 or Nc3 you neutralise it and keep your centre. Against Qd7 and Qd6, your winning percentage jumps to 59.1% and 59.2% respectively, because Black places the queen on passive squares where it blocks their own pieces. In every case, your follow-up is the same: Nc3, Nf3, and Be3 or Bd3, building a harmonious setup with a powerful d4-pawn and active pieces.
