Opening Repertoire

I got a question, what is a good repertoire for me. I really enjoy the french for 1 e4, I'm not really sure what to play vs 1 d4. I also enjoy Queen's gambit for white, but I enjoy mostly all openings for white, so openings for white would be helpful too. I'm like 1400-1500 USCF at the moment.

so please let me know what you guys think.

To play d5 against d4 is very common. White will then generally play either c4 or e3, and I respond with e6. It has worked well for me.

French can be played against d4 too, then you can decide to choose between slav-semislav, dutch etc.

If you feel comfortable with the light square pawn chain, I would suggest the Stonewall against d4. This allows you to reply e6 against anything white tries, and the pawn are similar. Since you adopt the Stonewall as black, you might as well try it as white.

Queen's gambit declined 1 d4 d5 2 c4 e6, Nimzo-Indian Defense 1 d4 Nf6 2 c4 e6 3 Nc3 Bb4, Queen's Indian Defence 1 d4 Nf6 2 c4 e6 3 Nf3 b6, Bogoljubov Indian Defense 1 d4 Nf6 2 c4 e6 3 Nf3 Bb4+, Dutch Defence 1 d4 e6 2 c4 f5
All have the move ...e6 like the French.

Do not try the dutch just because it includes e6. It is a fierce attacking opening, that doesn't have the same style with the French(except the Winawer). A Queen's indian or a Semi-Slav would be the best (and if your opponent allows the Nimzo, then definitely play it). So I recommend a move order like 1. d4 Nf6 2.c4 e6 and if 3. Nc3 Bb4 (Nimzo) or if 3.Nf3 b6 (QID). If you prefer the semi-slav, then just 1. d4 d5 2.c4 c6 3.Nc3 Nf6 Nf3 e6

Both Botvinnik and Bronstein used to play French and Dutch. The sequence 1 d4 e6 happened in their world championship match, letting white chose between Franch and Dutch. Carlsen played the Dutch Defence regularly.

just play e6 to d4 and play a nimzo if they play c4 and if they play 2 e4 then your back in the french you love

Carlsen can play everything with ease, and still he prefers slow positional openings. You can't show as an example the world champion because he has a full repertoire

Hi, my suggestion is: choose an your own repertoire and do not change it. Universal players exist but if you study well your openings then you cannot be crushed in opening and you can go to middlegame or even endgame with a certain security.
