1. d4 d5 2. c4 dxc4

The Queen's Gambit Accepted, often abbreviated to QGA, is the third most common response to the Queen's Pawn Gambit. It is characterised by the moves:

1. d4 d5
2. c4 dxc4

It comprises ECO codes D20-D29. Superficially, white has sacrificed a pawn to allow rapid development; however, the position often becomes quite complex.

Irregular Responses

ECO Code D20 contains all irregular variations. Specifically, it includes every response from white apart from 3. Nc3, the main line.

The noteworthy openings in D20 are:

• Linares Variation (3. e4 c5)
• Schwartz Defense (3.e4 f5)

Also occasionally seen is 3. e3, with a discovered attack on black's pawn. What usually follows is an opening of the position; 4.Bxc4 exd4 5.exd4; the result, while never studied deeply, is considered quite complex. To avoid this, black may opt to transpose to the Queen's Gambit Declined with 3... e6.

Regular Responses

Among the responses to 3. Nc3, there are:

• Queen's Gambit Accepted, Main Line, 3... Nf6 (D23-29)
• Alekhine Defense, 3... a6 (D22)
• Ericson Variation, 3... b5 (D21)

D21 also contains other responses from black; however, none of them are of any note.
