In fact, what i'm looking for its a black opening that would allow positional games, so i dont know if you have recommendation, i'm ranked 1700 on lichess
Best black opening

I suppose you like fianchettos since you play the english and reti ? Did you consider playing sorta the reverse English or accelerated dragon the maroczy may be a problem though there's always the 1...e5 lines with g6 IM Poucin mentioned in my thread on sister openings
Not all lines of the English involve fianchettoing the Bishop.
1.c4 e5 2.Nc3 Nf6 3.Nf3 Nc6 4.d4
Same line but 4.e3
1.c4 c5 2.Nf3 Nf6 3.d4 (anti-Benoni)
There are of course others.

I'm partial to the Caro-Kann as black. It's a solid positional opening, yet inherently asymmetrical. It gives black excellent opportunities to play for a win, even if white wants a draw. For theory, I can recommend the books by Schandorff and Houska. Either one would serve you well.
Against d4 I play a wider variety of openings, since I haven't yet discovered one that feels perfect for me. Most commonly I play some sort of Nimzo or Bogo-Indian. Sielecki's book has worked for me.

He's looking for an imbalance though. Just the opposite of what 1...e5 and 1...c6 openings do.
Given his criteria, he'd be better off playing either the Sicilian or French against 1.e4.

I think this all totally depends on your personal playing style, and of course what moves your opponent plays.

It depends what is best for YOU. What you find comfortable etc. I love the Caro-Kann, it leads to really interesting positions that I enjoy. But it's not the most aggressive opening. You get to attack in a lot of variations though, as white tries to hold onto the weaknesses he creates because he has a spatial advantage.
Hello everyone!I'm back up from playing chess these holidays, and I really want to learn black opening which allows counterattacks and make dynamical counterbalance. With White, I enjoy to play the English opening and the Reti, but I don't know any theoretical things about black opening. In the First book of John Watson, he describes that there are 2 plans for black: 1)playing for finding equality 2)trying to create an unbalance in order to
Find counterparts. I would like to find openings for the 2) and if you have a book or references that explain the theory, that would be cool.
