White has several sensible options here, and the statistics reveal clear patterns. By far the most common move is 4.Nc3, seen in over 2.4 million games, where White scores 51.8%. Next is 4.Bg5 (1.18 million games, White scores 50.5%), the classic QGD pin. 4.e3 (880,000 games) gives White only 49.6% — the worst score of the main moves — while 4.g3 (794,000 games) actually gives White the best results at 54.6%. The sharp 4.cxd5 (346,000 games) and the quieter 4.Bf4 (237,000 games) round out the field. Your job as Black isn't to memorise a forced line against each one, but to understand the typical plans each move allows.
The Critical Continuation: 4.g3
The engine's top choice is 4.g3, preparing to fianchetto the bishop on g2. The idea is to complete development with Bg2 and then put pressure on the centre. If White plays the engine's preferred sequence — 4.g3 dxc4 5.Bg2 Bb4+ — you get a Catalan-style position where Black has grabbed a pawn but must return it at the right moment. The engine evaluation of +0.34 reflects White's comfortable development, but Black's structure remains solid and there's plenty of play. Statistically, White scores 54.6% after 4.g3, so it's a challenging line you should be prepared to face.
The Big Mistake: 4.Bf4
Among the common moves, 4.Bf4 stands out as a clear inaccuracy. According to the engine, it loses roughly 0.8 pawns compared to the best move 4.g3. While the bishop looks natural on f4, it can become a target and White ends up with a slightly misplaced piece. In over 237,000 games White still scores 50.4% after 4.Bf4 — not a disaster by any means — but if your opponent plays this, you can be confident that you are already out of the opening with a small edge. Punishing it requires precise play, and the drill below will show you how.
How Black Should Think in This Position
The Queen's Gambit Declined is about solid development and patience. As Black, your pawn chain on d5 and e6 gives you a firm foothold in the centre. Your plan is usually to develop the kingside, castle short, and eventually challenge White's centre with ...c5 or ...e5. Watch out for the Bg5 pin (the second most popular move) — you'll typically respond with ...Be7 and ...Nbd7 before dealing with it. The statistics show that Black wins 44.5% of games from this position, which is a healthy percentage for the second player. Trust the structure, don't rush, and your chances are real.
