Generic opening for black



Everything that Fireline said.
Also, the Queen's Gambit is not an opening that you can play every game as White anyway... Black needs to comply
You've definitely chosen the wrong way to go about this. You should reconsider.
Should you go down the opening principles route, which I think you should, you can start here www.chess.com/article/view/the-principles-of-the-opening.
If you go the 1.e6 route then you will end up going for a French or queens gambit declined depending on if white plays 1.e4 or 1.d4. If he plays 1.e4, then you'll want to aim for the d5 square- knight on f6, bishop on e7, pawn on d5, Queen knight on d7 and your queen bishop can try to play on b7 or sit at home on c8 for a bit. Sometimes you may want to play c6. The idea is to gain control of the d5 square and then look to play either c5 or e5 to break the position open for you.
There are other systems and openings for sure but you will have a very tough time learning and knowing what set up works best against whites set up. Because you are giving what a free hand initially to develop how he wants, you'll come across a lot of different white set ups. But that may be a good thing for your development anyhow, even if you feel frustrated at times.
Hi all, I'm new to the forum ☺
I'm picking chess up again after 20+ years. This time, I'm determined to do it properly. As white I am studying all the possible variations as deep as I can for queens gambit.
However, I know this will take a huge amount of time and I am going to devote 12 months to it.
However, this means I will be lacking in my development for openings for black.
What is the best single generic black opening that I can use now, to at least give me a foothold in most games?
Obviously I know I eventually will have to study as black as hard as I am doing for white, but I need to start somewhere ☺
