I've started playing the QGA recently too and I really like it. It seems like quite a no-nonsene approach and some of the lines can be pretty imbalanced and interesting. The 3. e4 lines are fun to play against and in the 3. Nf3 4. e3 lines you can often force an isolani which leads to an interesting game.
The only thing is you've gotta be willing to play a wide variety of postions as White can play either some pretty sharp lines with 3. e4 or very quiet ones e.g. in the 3. Nf3 4.e3 lines where he takes on c5 and trades queens :P
For the past six months I've been looking at various defenses to the Queen's Gambit - Nimzo, Ragozin, QGD, Chigorin, Slav, etc. I play against Stockfish and find that I commonly get wrapped up and squeezed to death.
A number of times in books or articles about opennings I've run across comments like "this usually transposes from the Queen's Gambit Accepted or this transposes to the Queen's Gambit Accepted."
Most texts describe the QGA as insipid, dull and unintersting so I've pretty much ignored it. But I started playing with it the last few days and I'm finding it a real breath of fresh air. Black strikes back at the center immediately and the pieces pretty much come out to "where they are supposed to." It's easy to develop, castle and get a game going with the computer before getting knocked out in the final round.
I don't believe the QGA gives Black an advantage necessarily but all disadvantages aren't created equal. White has a bit more space but doesn't really get a lead in development. He also commonly gets an isolated center pawn which can be good or bad as time goes by. That's part of what defines White's space advantage.
My question really is about if I'm just seeing it this way because I'm playing against a computer and trying to prevent myself from losing right away?
What sort of experience do folks have playing for or against the QGA.
