Queen's Gambit Declined

The Queen's Gambit Declined (1.d4 d5 2.c4 e6) is Black's classical, rock-solid answer to the Queen's Gambit. Black refuses the c4-pawn and keeps a firm pawn on d5, accepting a temporarily passive light-squared bishop in exchange for a very sound position.

Origins

The QGD has a long history and became particularly common in the early 20th century. In the 1927 world championship match between Alexander Alekhine and José Raúl Capablanca, 32 of the 34 games began with the Queen's Gambit Declined. Among its many named lines, the Tarrasch Defense is named after Siegbert Tarrasch and the Ragozin Defense after the Soviet master Viacheslav Ragozin. The Cambridge Springs line takes its name from the 1904 tournament in Pennsylvania. It is still played at world championship level: Viswanathan Anand won the final game of the 2010 match with the Lasker Variation.

The idea

With 2...e6 Black supports d5 and prepares ...Nf6, ...Be7 and castling. The problem is the c8-bishop, which is shut in behind the e6-pawn. Much of Black's play is about freeing it, with ...b6 and ...Bb7, with ...dxc4 and ...c5, or with ...e5. White tries to exploit the passivity of that bishop. A famous plan is the minority attack in the Exchange Variation, where White advances b4–b5 to create a weakness on c6.

Main lines

• Orthodox Defense: 4.Bg5 Be7 5.e3 O-O 6.Nf3 Nbd7, the classic main line of the Modern Variation.
• Exchange Variation cxd5 exd5: the minority attack or a central pawn advance.
• Harrwitz Attack 4.Bf4 (5.Bf4 in some move orders): an alternative to Bg5 that limits Black's chances to exchange with ...Ne4.
• Ragozin Defense ...Bb4: a more active setup, related to the Nimzo-Indian.
• Tarrasch Defense 3...c5: Black accepts an isolated d-pawn for free piece play. The Semi-Tarrasch avoids the isolated pawn.
• Counter-attacks after 2.c4: the Albin Countergambit 2...e5 and the Chigorin Defense 2...Nc6. Both are strictly speaking separate openings.

Strengths and weaknesses

Strengths

• One of the most solid defences in chess. Black rarely gets into immediate trouble.
• Clear, well-understood plans that teach classical strategy.
• Played in world championship matches from Alekhine–Capablanca in 1927 to Anand–Topalov in 2010.

Weaknesses

• Black is passive for a while, and winning chances are limited against a careful opponent.
• The c8-bishop can remain a problem if Black misses the right freeing break.
• It needs positional patience; players who want early tactics find it dull.

Who should play it

The QGD suits positional players who want a reliable defence against 1.d4 and are happy to wait for chances. It is good against aggressive players who overpress, because Black's position has very few weaknesses. It is less suited to players who must win with Black, since a well-prepared opponent can choose the Exchange Variation, whose long-term features favour White. For a more active alternative, consider the Slav or the Nimzo-Indian.

The numbers

On Lichess White wins 51–52% below 2200 and Black 44%. Above 2200 it is 49.5% against 42%. In master games over the board, draws dominate at 47%, White wins 33.5% and Black 19%.
