Queen's Gambit Declined: The cxd5 Line – How to Play as Black

You have a pawn on d5 facing White's pawn on d4 — a classic symmetrical centre. Your light-squared bishop is free to develop, your queen's knight can go to c6 or d7, and your king is safe behind a solid pawn chain. White's main idea is to pressure your centre while developing quickly, but you are not cramped. The structure is balanced: White has more space on the queenside, you have a solid foothold in the centre. No weak squares, no backward pawns. Your job is to complete development and watch for White trying to gain a tempo with Bf4 or Nc3. This is a position where understanding typical plans matters more than memorising long forced lines.

Stockfish's favourite move for White at depth 16 is Nc3 — developing the knight and eyeing both the centre and the d5 pawn. The suggested follow-up is Nc3 c6 Bf4 Nf6. This is a natural, principled plan. Your response with c6 solidifies the d5 pawn and prepares ...Bf5 or ...Be6 later. Then ...Nf6 develops and fights for control of e4. Notice that White plays Bf4 before e3 — this is a common modern approach to avoid blocking the bishop. If White plays Nc3 against you, you are in the main line. Stay calm, develop your pieces, and you are fully equal.

With over three million games to draw from, we can see which moves White tries most and how they score. Nc3 leads the pack by a huge margin — nearly two million games — and White scores 49.4%. That's barely above average. Nf3 is the second most popular at 48.7% for White, and e3 actually scores slightly worse at 47.1%. Interestingly, Bf4 (which the engine recommends after Nc3) sees White scoring 49.5% when played as a first move too. The key takeaway: no move gives White a significant statistical edge. That confirms the engine's verdict — this is a level position where good play, not the opening choice, decides the game.

One move in particular stands out as a mistake. White playing g3 early in this position is classified as an inaccuracy — it loses roughly 0.5 pawns of advantage. Stockfish strongly prefers Nc3 instead. The problem with g3 is that it weakens the kingside dark squares and does nothing to contest the centre. If White plays g3 against you, they are effectively giving you a small but real edge. Develop quickly, occupy the centre, and you will have a comfortable position. In the database g3 appears only 35,093 times out of over three million games — strong players rarely touch it. Knowing that g3 is a mistake gives you confidence to face it when it appears.
