The Queen's Gambit Declined (QGD) is a chess opening
Chess opening
A chess opening is the group of initial moves of a chess game. Recognized sequences of opening moves are referred to as openings as initiated by White or defenses, as created in reply by Black. There are many dozens of different openings, and hundreds of named variants. The Oxford Companion to...

Queen's Gambit

:
1. d4 d5
2. c4

Instead of 2...dxc4, Black instead plays one of various defenses. A common response by Black is:
2... e6


This is known as the Orthodox Line of the Queen's Gambit Declined. When the opening Queen's Gambit Declined is mentioned, it is usually assumed to be referring to the Orthodox Line.

The Orthodox Line can be reached by a number of different move orders, such as 1.d4 e6 2.c4 d5; 1.d4 Nf6 2.c4 e6 3.Nf3 d5; 1.c4 e6 2.Nc3 d5 3.d4; 1.Nf3 d5 2.c4 e6 3.d4; and so on.

 sacrifice, Black erects a solid position; the pawns on d5 and e6 give Black a foothold in the center. The Orthodox Line of the Queen's Gambit Declined has the reputation of being one of Black's most reliable defenses to 1.d4. In this situation, White will try to exploit the passivity of Black's light-squared bishop, and Black will try to release it, trade it, or prove that, while passive, the bishop has a useful defensive role.

An eventual ...dxc4 by Black will surrender the center to White, and Black will usually not do this unless he can extract a concession, usually in the form of gaining a tempo, by capturing on c4 only after White has played Bd3 first. In the Orthodox Line, the 'fight for the tempo' revolves around White's efforts to play all other useful developing moves prior to playing Bd3.

Other lines

In its broadest sense, the Queen's Gambit Declined is any variation of the Queen's Gambit in which Black declines to capture White's pawn on c4. Variations other than the Orthodox Line have their own names and are usually treated separately.

  • The Orthodox Defense: 4.Bg5 Be7 5.e3 0-0 6.Nf3 Nbd7 7.Rc1 c6 and now White has two main moves: 8.Bd3 and 8.Qc2. After 8.Bd3 dxc4 9.Bxc4 Black has surrendered the center and stands somewhat cramped, but has succeeded in making White lose a tempo by playing Bd3 before Bxc4. White will try to use his advantage in space to attack, whereas Black will try to keep White at bay while striking back at the center. Capablanca's main idea here was the freeing maneuver 9...Nd5 10.Bxe7 Qxe7 11.0-0 Nxc3 12.Rxc3 e5 13.dxe5 Nxe5 14.Nxe5 Qxe5 15.f4 Qe7, which has led to a number of exchanges in the center, though Black must exercise care even in the wake of this simplification. This line was once so frequently played that it has a separate code (D69) in ECO, though the lack of active counter play for Black has made the main line of the Orthodox a backwater in modern practice.

The Exchange Variation

1.d4 d5 2.c4 e6 3.Nc3 Nf6 4.cxd5 exd5 and White has a pawn majority in the center, Black has a pawn majority on the queenside. This pawn structure gives White the opportunity to either advance his pawns in the center by means of Nge2, f2–f3, followed by e2–e4, or play for a minority attack by means of the plan Rb1, followed by b2–b4–b5, then bxc6 in order to create a weak pawn at c6. While Black can play ...cxb5, or recapture on c6 with a piece, each of these possibilities are even less desirable than the backward pawn

White pawns or pieces to occupy the central squares in exchange for long-term pawn structure weaknesses. An instance of Vienna variation played at the highest level was Fine vs Euwe, AVRO 1938.
