I think you need to try openings out for yourself. Don't be fooled into thinking the winning statistics here at the Game Explorer or in any other DB have to apply to you and your opponents, because they don't. Offhand the QGA is a good place to start IMHO there's much less theory to it than in the QGD which has 2 major branches - the orthodox lines beginning with 2...e6 and Slav/Semi-Slav lines beginning with 2...c6, and each branch has several major openings with lots more major variations.
There are different variations of the QGA but IMHO they have more in common with each other than all the major lines in the QGD.
For lots more info type Queens Gambit Accepted into a search engine and I noticed several (at least) YouTube videos about it

I have been looking at a lot of lines in the QGD lately (Tartakower, Lasker defense, orthodox defense, cambridge springs, etc...) and I was wondering what people think about them. Which line is your favorite? which gives black the best winning chances?
Also does anyone play the Queen's Gambit Accepted? I was looking at that too it seems like it could be an interesting surpise.
