Thanks for your reply, I am going through the Starting Out: QGA book and selecting lines/chapters that I intend to play, I will go with the immediate exd4 which is more concrete.  Wink

I wish Rizzitano's book How to beat d4 was more readable. The lack of explanations makes the lines hard to remember and it has a hardcore tree format.

No problem.  Smiley

I figured that was what you wanted to say, but I couldn't resist cracking a joke.

I don't have a lot of experience with these 3.e4 QGA lines, but what little I have is on the White side. Quite apart from any objective verdict, my feeling was that the ...Bb4+ lines were relatively easy to play for White, with only a small amount of theory you really had to remember. It's possible to play those positions decently for White even if you have forgotten the theory.

While 4...exd4 felt a lot trickier: I've tried both the long main line with Qxb7 and the alternative 7.Bb5!?, but only managed draws with both. Avrukh in the second incarnation of his 1.d4  repertoire claims that 7.Bb5 has been completely defanged (by some engine or corr games)-So that leaves the main line 3...e5 4.Nf3 exd4 5.Bc4 Nc6 6.0-0 Be6 7.Bxe6 fxe6 8.Qb3 etc. Avrukh claims White ends up better, but even if that's correct it involves remembering or finding a lot of very accurate moves. Black has a weakened pawn structure, but on the plus side he has the half-open f- and b-files and chances of a kingside attack if White plays too slowly. I think Black players could do very well with this if they specialize. Of course it does require Black to also be happy with a complex/unbalanced middlegame arising.

Of course Black players also have different playing styles and preferences. A solid, technical player as Black may well do better with 4...Bb4+, which often leads to one or two pairs of minor pieces being exchanged and more well-known pawn structures arising.

I don't know what the hell was going through my mind (a cold draft?) I edited the OP, now it makes sense!  Cheesy

There are two responses that I am considering, one is the immediate 3. ...e5 and the other is to first give a check with 3. ...Bb4+ and then maybe play e5. The engines prefer the immediate e5.

Can't jump over the pawn.

This is just like the Accelerated Trompowsky: 1. Bg5!, flexibly waiting with the d-pawn to see if it belongs on d4 or d3.

I wonder how you got engines to even consider 3...Bb4+.

No wonder engines prefer 3...e5.

Which do you think is best from a practical OTB standpoint, assuming the opponent is not expecting the QGA and is not booked up? And why?
