Playing the Queen's Gambit Declined: Tarrasch Defense, Pseudo-Tarrasch: cxd5 as Black

In the Pseudo-Tarrasch, Black challenges White's centre early with ...c5. By the time you reach this position after 4...exd5, you have already traded your e-pawn for White's c-pawn. The pawn structure is symmetrical — both sides have a d-pawn facing each other — but White has the move and a slight lead in development. Your main goal as Black is to complete development smoothly, keep the centre stable, and eventually target White's d4-pawn or create counterplay on the queenside. The engine's +0.36 evaluation tells you that White has a small plus, but nothing decisive. With accurate play you can neutralise that edge and steer the game toward an equal middlegame.

Stockfish recommends Bg5 as White's strongest continuation. The idea is to pin the knight on f6 (after ...Nf6) or force Black into a pin after ...Be7, Bxe7 Qxe7. This exchange removes Black's dark-squared bishop and slightly weakens the dark squares around your king. It also leaves Black with a queen on e7 that can be a target for later tactical ideas. This line scores a sharp 57.1% for White across nearly 11,000 games, so you need to be ready for it. The engine's best response for Black is to accept the trade: Bg5 Be7 Bxe7 Qxe7. After that, Black has completed development, the queen on e7 is active, and the position remains playable. Don't fear the bishop exchange — it's a normal part of this line.

With 237,408 games in the database, you have a huge sample to learn from. Here is how each of White's most popular moves scores, and what they mean for you as Black: - Nc3 (76,387 games, White scores 53.1%): The most common move. White develops a knight and keeps tension. Black's best reply is usually ...Nf6, with a solid game. - dxc5 (62,492 games, White scores 48.2%): White takes the c-pawn, giving you an isolated queen's pawn after ...Bxc5. This is one of White's lowest-scoring options — a good sign for you. - e3 (47,191 games, White scores 49.6%): A quiet, solid choice. Black can play ...Nf6 or ...cxd4. - g3 (24,770 games, White scores 58.3%): The fianchetto setup scores very well for White. Be careful here — White wants to control the long diagonal. - Bg5 (10,837 games, White scores 57.1%): The engine's top pick and a high-scoring move for White, as discussed above. - Bf4 (9,862 games, White scores 49.5%): Another reasonable Bishop move, but White doesn't score well from it. Notice that the moves where White scores below 50% — dxc5, e3, and Bf4 — are the ones where you as Black have the most to hope for. That 48.2% White score after dxc5 is especially encouraging.

While the FACTS for this specific position don't list a single top mistake, the statistics point to a clear danger: reacting passively. The highest-scoring White moves (g3 at 58.3% and Bg5 at 57.1%) are aggressive, developing moves that put pressure on Black. If you respond with a timid or slow move — something like ...Be6 too early, or pushing a pawn without reason — you allow White to increase that +0.36 advantage. The general principle here is to keep up in development: get your knights out (Nf6, Nc6), castle quickly, and don't let White dominate the centre. In the Bg5 line, the recommended sequence Bg5 Be7 Bxe7 Qxe7 is a good model: you exchange on your terms and bring your queen to a useful square.
