Okay but you need to look more closely at the line 1.d4 d5 2.c4 dxc4 3.e4 b5 4.a4 c6 5.axb5 cxb5 6.Nc3 a6 7.Nxb5 axb5.
Refutation of the Greedy Queen's Gambit Accepted

Yes, all this has been well known for many, many years--so long that no new theory appears in this line as no masters play it. And the actual equalizing line after 3.e4 is .....e5.
I tried to give you a hint. YouShisno knows what I am talking about, but your response was "no new theory" and "no masters play it"? I guess you don't take a hint.

There are many more games in this line. After 8...Bb7 white scores 56% in database.chessbase.com. Above 2500 white scores 50%.

What really baffles me is that game ended in a draw. White was winning. Then again, I don't play a lot of long OTB games where I have to calculate everything.
Everyone has hear that the Queen's Gambit is not really a gambit because White wins back the pawn. There have been times where I've struggled to win it back but I'm going to show you all how to regain the pawn or have a winning position
