QGD: Orthodox Defense — The cxd5 Exchange
After 1.d4 d5 2.c4 e6 3.Nc3 Nf6 4.Nf3 Be7, you reach one of the classical battlegrounds of chess: the Queen's Gambit Declined. When White trades pawns with 5.cxd5 exd5, the centre clears and the fight becomes about piece activity and control of the e4-square. You, as Black, have weathered the early storm — your position is sound, your development is on track, and the engine calls this dead level (+0.17 for White, meaning you are neither better nor worse). Below, we'll walk through the main continuations, the statistics from 170,625 real games, and the one White inaccuracy you can punish right away. Then test yourself against the drill.

The pawn on d5 gives Black a solid foothold in the centre. Your key ideas are straightforward: develop your pieces naturally (Nc6, 0-0, Bg4 or Bf5), keep the pawn chain intact, and challenge White's attempt to seize space. The symmetrical pawn structure after 5...exd5 means small advantages come from piece placement and the half-open e-file. White's queen often goes to c2 to support the c3-knight and press the d5-pawn, while Black's light-squared bishop looks for an active diagonal. The engine evaluation (+0.17) confirms what masters have known for over a century: this is a fair fight. Your job is to complete development without creating weaknesses, then outplay your opponent in the middlegame.
The Engine's Top Choice: 6.Qc2
The computer's preferred continuation is 6.Qc2, which prepares rapid queenside castling or supports a later Bf4/Bg5 without blocking the c1-bishop. The engine's full line runs 6.Qc2 Nc6 a3 Bg4 — both sides finish development and the game remains balanced. In practice, Qc2 is the least common among White's main options (just 2,921 games), but it scores the worst for White at 44.2%. That doesn't mean it's bad — rather, Black players have handled it well because the position is straightforward. If you see 6.Qc2, simply continue with ...Nc6 and develop your bishop actively on g4. The engine's plan for White (a3, then Bg4) shows that White respects your bishop's activity and wants to prevent ...Nb4.
White's Most Popular Moves — What the Numbers Say
From the diagram, White has five serious options. Here's how Black scores against each one based on 170,625 Lichess games (White win / draw / Black win):- 6.Bg5 (50,614 games): White 48.7%, Draw 4.6%, Black 46.7%. The classical pin on the knight. Black can break it with ...0-0 and ...Be6 or play ...h6 and ...g5 if feeling ambitious. Black scores almost evenly.- 6.Bf4 (43,753 games): White 50.0%, Draw 4.8%, Black 45.2%. White's sharpest scoring choice. Black's most reliable answer is ...c6, ...Bd6, or ...Nc6 — don't panic, just develop.- 6.e3 (41,909 games): White 45.8%, Draw 4.7%, Black 49.5%. The quietest move, and Black's best-scoring response at nearly half the points. You should be happy to see this — it gives White a cramped setup.- 6.g3 (16,616 games): White 47.6%, Draw 4.6%, Black 47.8%. This is an inaccuracy that loses about 0.7 pawns of advantage. Black gains a comfortable edge after ...Bf5 or ...Bg4, exploiting the weakened dark squares.- 6.h3 (4,150 games): White 49.1%, Draw 4.7%, Black 46.2%. A prophylactic move preparing g3 or Bf4. Solid but passive.
The Mistake to Punish: 6.g3
According to the engine, 6.g3 is a clear inaccuracy — it throws away White's opening advantage and gives Black a ~0.7-pawn edge. White's idea is to fianchetto the bishop on g2, but the pawn on g3 weakens the f3-square and does nothing to control the centre. Black can respond with 6...Bf5 or 6...Bg4, pressuring the knight on f3 and eyeing the queenside. In practice, Black scores 47.8% from this position, which is respectable. If your opponent plays 6.g3, don't hesitate — put your bishop on an active square and enjoy the extra space. The engine says White should have played 6.Bf4 instead.
