The Bishops Bounty: Queens Gambit (Accepted) D20

Queen's Gambit Accepted Resources

Wikipedia Page
The Queen's Gambit Accepted (or QGA) is a chess opening characterised by the moves:
1. d4 d5
2. c4 dxc4

The Queen's Gambit Accepted is the third most popular option on Black's second move, after 2...e6 (the Queen's Gambit Declined) and 2...c6 (the Slav Defense).

The Queen's Gambit is not considered a true gambit, in contrast to the King's Gambit, because the pawn is either regained, or can only be held unprofitably by Black. Black usually allows the pawn to be recaptured, and uses the time expended to play against White's center.
