Queen's Gambit Accepted with 3. Nf3 According to wikipedia in the main line of the Queen's Gambit Accepted White's 3rd move is: 3.Nf3:



[FEN ""]
1. d4 d5 2. c4 dxc4 3. Nf3



Doesn't that pretty much turn the opening into a real gambit? Black can now hold on to the c-file pawn since the usual trap (with Qf3) is no longer possible and b4 can be safely played by Black to prop up the c-file pawn.

No he can not. White will regain the pawn and get huge advantage.
