Well, just developing and expanding in the center should be enough for a slight edge. I believe that Na3 wins the pawn back as well, with an advantage.
queen's gambit accepted
It is the worst move in that position. This is blocking the e pawn. Simply just play Na5, and you will have better position. Other solution could be d5 (you cant play it right now) but that would block your bishop, when it captures to c4. Ok, after Na5 black still has Qd5, but that cant be good.

With the bishop being in front of the pawn it seems like a poor move to me. Yet phren showed to top level players using it. Also b5 trying to save the pawn seems poor. Is this move used by top level players and why would they give up so much control over the center in trying to save that pawn gambit
macer75: No, Queen's Gambit is the moves 1. d4 d5 2. c4, where white offers the C-pawn in exchange for black having a reduced presence in the middle. If black takes the C-pawn with 2...dxc4, the opening becomes the Queen's Gambit Accepted.

Thanks for the explanation SgtDoodles. But I knew what Queen's Gambit is. I was just making a bad attempt at a joke. :)

What's everybody talking about? I thought queens gambit was when you sacrificed your queen?
Then what is the King's Gambit Accepted?

There are always counter-examples. GM Anatoly Vaisser recommends 4.Nd2 (IM Angus Dunnington also used to play this) in this line and prefers 7.Nce5 to 7.Qb3. Vaisser is former French champion and former World Senior champion. He has defeated guys like Tal, Polugaevsky, Ivkov, Larsen, Anand, Short, Psakhis, Van Wely and dozens of other GMs.

Chessbase database has 8 games with 7...Bd5. One win (a 2206 player beat a 2333 player in 2011 at Dresden in 21 moves), one loss, and 6 draws. White scored with 8.Qa4 (Fritz 13 and Rybka 4 give a slight advantage to White after this move). Other responses were Nxc6, dxc5, and Bd2.
Also, IM Sam Collins (2002 Irish champion) improved on 9.Nd4 (the Braun-Thomaa game) and played 9.Qb5, drawing with Thomas Luther in 20 moves in this same variation at the 2008 European Union Ch.
After 3...Be6, GM Sam Shankland likes 4.Nf3, but he did lose to Levon Altounian in the 2010 US Ch after 4.Nf3 Nf6 5.Nc3 h6.
in the qga line ,after 1.d4 d5 2.c4 dxc4 3.e3...
why cant black support the pawn with the bishop.
what can white play against this.
