Queen's Gambit Declined: Tarrasch Defense, Pseudo-Tarrasch – Playing Black After 4...Bxc5
After 1.d4 d5 2.c4 e6 3.Nf3 c5 4.dxc5 Bxc5, you've reached the Pseudo-Tarrasch line of the Queen's Gambit Declined. You've traded a centre pawn for rapid development, and your bishop on c5 already eyes White's kingside. Stockfish evaluates this position at +0.28 — a small edge for White, meaning you are slightly worse out of the opening according to the engine. But the database tells a different story: across nearly 100,000 games, Black scores 46% wins and White only 49.1%, with the rest drawn. That's practically level. The real fight starts now, and knowing a few details gives you excellent practical chances.

The defining feature of this position is the pawn on d5. White's most popular move by far is 5.cxd5 (over 50,000 games), immediately testing whether you can recapture comfortably. After 5...exd5, the centre clears and the game becomes an IQP (isolated queen's pawn) structure — Black has an isolated pawn on d5, but excellent piece activity to compensate. Your bishop pair, especially the one on c5, becomes a real weapon. The engine's top continuation is 5.cxd5 exd5 6.Qc2 Bb6, where you retreat the bishop to a safe square while keeping pressure on the centre. Don't panic about the isolated pawn: in club-level play, the activity you get often outweighs the structural weakness.
The Critical Moment: White's Best Reply
The engine's best move in this position is 5.cxd5, and knowing how to respond is essential. After 5...exd5, you reach a classic IQP position. White's follow-up 6.Qc2 is precise — the queen attacks the c5 bishop, which is why 6...Bb6 is the engine's recommendation. This retreat looks modest, but it keeps your bishop on a strong diagonal (aiming at f2) and forces White to finish development before gaining space. The resulting middlegame sees Black playing for piece activity and attacking chances against White's king, while White will try to prove the d5 pawn is a long-term weakness. Your job: develop quickly, castle kingside, and look for opportunities to play ...d4 or ...Bg4 to create pressure.
What the Numbers Say: Nearly Even
The statistics from over 97,000 games are surprisingly balanced for a position the engine calls slightly favourable for White. Here's how White's main options score in practice: after 5.cxd5, White scores 49.5% — essentially nothing. After 5.Nc3 (18,434 games) White scores 49.0%, and after 5.e3 (13,965 games) White scores 49.8%. Even the 'inferior' move 5.Bg5 scores 47.6% for White across 2,535 games, which is only slightly below the other lines. What does this tell you? The position is razor-sharp and the engine's tiny +0.28 edge doesn't translate to easy results for White in real games. As Black you can play this line confidently knowing your practical chances are excellent.
A Mistake to Watch For
The database flags 5.Bg5 as an inaccuracy, losing about 0.8 pawns in evaluation compared to the best move 5.cxd5. This is important because 5.Bg5 looks natural — it pins the knight on f6 (when it arrives) and develops a bishop. But in this specific position, it's a mistake. After 5.Bg5, Black can continue developing with moves like ...Nf6 and ...0-0, and the pin on the knight turns out to be less dangerous than it appears. White's queen's knight remains undeveloped, and Black's bishop pair and central presence give comfortable equality. If your opponent plays 5.Bg5, you should be happy — you've dodged the more challenging lines.
