@Inyustisia: So you are giving, just as one recommendation, the following (correct me where I am wrong):
When I am Black:
French (against 1.e4) and QGD (against 1.d4)
-OR-
Caro-Kann (against 1.e4) and Slav (against 1.d4)
Is that correct?
When I am White:
I'm lost at this point...
i have no idea where it might be coming from, but it seems that you are making some confusion regarding "repertoire for white" and "repertoire for black".
when you are white you have a choice of opening with d4, c4, e4, Nf3, whatever. let's say you pick e4.
you made the first big choice, then it's black's big choice whether he wants to play the french, the caro, the sicilian, the pirc, e5 or whatever (defences for black against e4). he can't play the slav, the qgd, the nimzo, the king's indian as these aren't replies to e4.
let's say he picks the french. then you can play the advance variation, the exchange, the tarrasch, nc3... if you pick nc3, then black can choose the winawer, the rubinstein, the classical... and so the players keep making choices until the theory is over.
