Queen's Gambit Declined
The gold standard of 1.d4 defences: decline the gambit, build a fortress, and outplay the opponent later.

Black declines the gambit and builds the rock-solid Orthodox structure, holding the d5-point and preparing to free the game with …c5.
The idea
When White offers the Queen’s Gambit with 2.c4, Black can simply decline it. The Queen’s Gambit Declined props up the d5-pawn with …e6, accepting a slightly passive light-squared bishop in return for one of the soundest, most reliable structures in all of chess. It has been the choice of world champions in title matches for a century precisely because it is so hard to break down.
Main line explained
After 1.d4 d5 2.c4 e6 3.Nc3 Nf6 4.Bg5 White pins the knight and piles pressure on d5. Black develops solidly with 4…Be7, breaking the pin’s sting, and castles: 5.e3 O-O reaches the classical Orthodox setup. 6.Nf3 completes development and 6…h6 politely questions the g5-bishop, gaining a small kingside foothold and clarifying White’s intentions before Black chooses a freeing plan.
Plans for both sides
White: White enjoys more central space and a natural plan: complete development, and either execute the "minority attack" (b4–b5 to create a weakness on Black’s queenside) or push in the centre with e3–e4 once fully mobilised. The pin on f6 and pressure on d5 give White the easier position to play.
Black: Black aims to free the game. The key breaks are …c5 (challenging d4) and, after …dxc4 at the right moment, …b5 or …c5 to activate the pieces; developing the problem bishop via …b6 and …Bb7, or the …Nbd7–f8–g6 regrouping, are thematic. Equality is very achievable with accurate play.
A common trap to avoid
Do not release the central tension too early with …dxc4. Capturing on c4 before White has committed hands over the centre for free and simply gives White a mobile pawn majority and a tempo (Bxc4). In the QGD, patience is a weapon: keep the pawn on d5 until capturing actually achieves something concrete.
Who it suits
Solid, classical players who want a lifelong, low-maintenance answer to 1.d4 and enjoy grinding out equal-to-better endgames rather than gambling in sharp theory.
In this line you play Black. The board above shows the position reached after 6...h6.
