Playing Black in the Queen's Gambit Declined: Tarrasch Defense, Pseudo-Tarrasch: g3

By grabbing the pawn on c4, you immediately put White's setup to the test. White has just played g3, intending to fianchetto the light-squared bishop and keep a strong centre. But 4...dxc4 says: if you want that pawn back, you'll have to spend time capturing it, and meanwhile Black will develop quickly and challenge the d4-pawn with ...c5. The engine's best reply, Bg2 (played in 6,440 games), is a calm developing move that keeps White's options open — it doesn't rush to regain the pawn. That tells you something: White doesn't have a way to punish your pawn grab. Your job is now to complete development, target the d4-pawn, and not let White's bishop pair become intimidating.

Stockfish's top choice is 5.Bg2, preparing to recapture the pawn with the bishop if you ever play ...b5 or simply developing with pressure along the long diagonal. The engine's suggested follow-up is 5...Nc6 6.Nbd2 cxd4, giving back the c4-pawn in order to eliminate White's d4-pawn. This is a clean, principled line where both sides have finished development early and the position simplifies into an equal middlegame. If White plays the more popular Bg2 (6,440 games, scoring 55.5%), you should aim for quick development and that central exchange. White's score inflates slightly because lower-rated players often mishandle Black's side, not because the position favours White.

The numbers reveal one clear danger: the move 5.dxc5 has been played 387 times, and White scores just 41.1% with it — the lowest of any major option. The engine confirms this is an inaccuracy costing about 0.8 pawns. If White captures on c5, you should be happy: the d4-square is gone, your bishop on c8 can develop freely, and you can recapture the c4-pawn with ...Bxc5 or prepare ...b5. White's second-most-popular choice, 5.Qa4+ (2,974 games, White scores 50.7%), checks your king but after 5...Bd7 (or 5...Nc6) White has nothing better than to retreat or recapture on c4. Your winning chances stay solid.

After the dust settles on the c4- and d4-pawns, Black usually ends up with an isolated queen's pawn (IQP) on d5 — or no central pawns at all if White recaptures on d4 with a piece. Neither structure is bad for you. With an IQP you get active piece play and central space; without it you have a clean, easy-to-play position. The g3 fianchetto means White's king is slightly exposed if the centre opens up, so keep an eye on long-diagonal tactics. Black's plan is straightforward: finish development (Nf6, Be7, O-O, Bd7 or Be6), put a rook on c8, and see if White overpressures. The engine says this is dead level — trust the position and your development, not flashy tactics.
