The '''Queen's Gambit''' is the [[chess opening]] that starts with the moves:<ref>{{Cite web|title=Queens Gambit - The Chess Website|url=https://www.thechesswebsite.com/queens-gambit/|access-date=2021-01-30|language=en-US}}</ref>

It is one of the oldest openings and is still commonly played today. It is traditionally described as a ''[[gambit]]'' because White appears to sacrifice the c-pawn; however, this could be considered a misnomer as Black cannot retain the pawn without incurring a disadvantage.<ref>{{Cite web|title=Queen's Gambit|url=https://chesspathways.com/chess-openings/queens-pawn-opening/queens-gambit/|access-date=2021-01-30|website=Chess Pathways|language=en-US}}</ref><ref name="mco14">{{citation|last=De Firmian|first=Nick|author-link=Nick de Firmian|title=Modern Chess Openings|edition=14th|year=1999|publisher=David McKay|page=387}}</ref>

==History==
The Queen's Gambit is one of the oldest known openings in chess. It was mentioned in the [[Göttingen manuscript]] of 1490 and was later analyzed by [[Gioachino Greco]] in the 17th century.<ref name="mco14" /> In the 18th century, it was recommended by [[Philipp Stamma]] of Aleppo and is sometimes known as the '''Aleppo Gambit''' in his honor.<ref>{{Cite book |title=The Works of Damiano, Ruy-Lopez, and Salvio on the Game of Chess |last=Sarratt |first=J. H. |publisher=T. Boosey, (the New York Public Library) (Digitized) |date=27 Jan 2006 |isbn=9781145601765 }}</ref>  During the early period of modern chess, queen pawn openings were not in fashion, and the Queen's Gambit did not become commonplace until the [[Vienna 1873 chess tournament|1873 tournament in Vienna]].<ref name="mco12">{{citation|last=Korn|first=Walter|title=Modern Chess Openings|edition=12th|year=1982|publisher=David McKay|page=263}}</ref>

As [[Wilhelm Steinitz]] and [[Siegbert Tarrasch]] developed [[chess theory]] and increased the appreciation of {{chessgloss|positional play}}, the Queen's Gambit grew more popular,<ref name="mco12" /> reaching its zenith in the 1920s and 1930s, and it was played in all but 2 of 34 games in the [[World Chess Championship 1927|1927 World Championship]] match between [[José Raúl Capablanca]] and [[Alexander Alekhine]].

After the resumption of international chess activity following [[World War II]], it was less frequently seen as many players moved away from symmetrical openings, tending to use an [[Indian Defence]] to combat queen pawn openings; however, it is still frequently played.

==Overview==
With 2.c4, White threatens to exchange a wing pawn (the c-pawn) for a center pawn (Black's d-pawn) in order to dominate the {{chessgloss|center}} with e2–e4. Black cannot hold the pawn, for example: 1.d4 d5 2.c4 dxc4 3.e3 b5{{chesspunc|?}} (Black tries to guard their pawn but should pursue {{chessgloss|development}} with 3...Nf6 or 3...e5) 4.a4 c6? 5.axb5 cxb5{{chesspunc|??}} 6.Qf3{{chesspunc|!}} winning a piece.

The Queen's Gambit is divided into two major categories based on Black's response: the [[Queen's Gambit Accepted]] (QGA) and the [[Queen's Gambit Declined]] (QGD). In the QGA, Black plays 2...dxc4, temporarily giving up the center to obtain freer development. In the QGD, Black usually plays to hold d5. Frequently Black will be cramped, but Black aims to exchange pieces and use {{chessgloss|pawn breaks}} at c5 and e5 to free Black's game.

== Variations ==
Technically, any Black response other than 2...dxc4 (or another line with an early ...dxc4 that transposes into the QGA) is a Queen's Gambit Declined, but the Slav, Albin Countergambit, and Chigorin Defense are generally treated separately. There are so many QGD lines after 2...e6 that many of them are distinctive enough to warrant separate treatment.  The Orthodox Defense and the [[Tarrasch Defense]] are two important examples.  (See [[Queen's Gambit Declined]] for more.)

After 1.d4 d5 2.c4:
* 2...e6 – [[Queen's Gambit Declined]] or QGD (''[[Encyclopaedia of Chess Openings|ECO]]'' D30–D69). This is the main line, with many variations.
* 2...dxc4 – [[Queen's Gambit Accepted]] or QGA (D20–D29). Less popular than the Queen's Gambit Declined, it nevertheless has a solid reputation.
* 2...c6 – [[Slav Defense]] (D10–D19). This is a solid response, although many variations are very tactical. If Black plays both ...c6 and ...e6 (in either order), the opening takes characteristics of both the Slav and the Orthodox Defense and is classified as a [[Semi-Slav Defense]].
* 2...e5 – [[Albin Countergambit]] (D08–D09), a sharp attempt by Black to gain the [[Initiative (chess)|initiative]]. It is uncommon in top-level chess but can be a dangerous weapon in club play.
* 2...Nc6 – [[Chigorin Defense]] (D07) The Chigorin Defense takes the game away from the normal positional channels of the QGD and has been favored by [[Alexander Morozevich]] at the top level; it appears to be {{chessgloss|playable}} for Black.
* 2...Bf5{{chesspunc|!?}} – [[Baltic Defense]] (D06), an offbeat but playable line.
* 2...c5 – [[Symmetrical Defense]] (D06). This is rarely played; although it has not been definitely refuted, the play seems to favor White.
* 2...Nf6{{chesspunc|?!}} – [[Marshall Defense]] (D06), named after [[Frank Marshall (chess player)|Frank Marshall]], who first devised the move, he briefly played it in the 1920s before abandoning it. 
* 2...g6?! – Alekhine idea<ref>{{cite book |last1=Benjamin |first1=Joel |author-link1=Joel Benjamin |last2=Schiller |first2=Eric |author-link2=Eric Schiller |title=Unorthodox Openings |publisher=[[Macmillan Publishers (United States)|Macmillan Publishing Company]] |year=1987 |page=97 |quote=Queen's Gambit Declined: Alekhine Idea '''1 d4 d5 2 c4 g6'''|isbn=0-02-016590-0}}</ref> (D06). White can gain the advantage by 3.cxd5 Qxd5 (3...Nf6 4.Qa4 {{chesspunc|+/−}}) 4.Nc3 Qa5 5.Nf3 Bg7 6.Bd2 c6 7.e4 Qb6 8.Bc4{{chesspunc|!}} Bxd4 9.Nxd4 Qxd4 10.Qb3 Qg7 11.0-0 +/− ([[Nikolay Minev|Minev]]).<ref>{{cite book |editor-last=Matanović |editor-first=Aleksandar |editor-link=Aleksandar Matanović |title=Encyclopaedia of Chess Openings |publisher=[[Chess Informant]] |location=Yugoslavia |volume=D |edition=2nd |year=1987 |page=44 |isbn=86-7297-008-X |title-link=Encyclopaedia of Chess Openings }}</ref>

If White chooses to [[fianchetto]] the {{chessgloss|king's bishop}}, the game transposes into the [[Catalan Opening]].
