beat opening for 700 rating


Hi as a beginner best to learn openings where you take the middle of the boards and develop pieces as that's what's needed to learn.
E4, e5
D4, d4 etc

Or be different but principled.
Me: as white = 1. c4, opponent says what?
Me as Black: 1. e4, c5
1. d4, e5 or g6
1. c4, c5
Any other opening I prefer c5 and get the accelerated dragon or Maroczy bind because they sound cool.
Enjoy a 65% win rate percentage while hearing “beginners should follow opening principles”.

Chess Opening Recommendations…
You might give the Vienna Game & Gambit a try. After 1.e4 e5, by introducing 2.Nc3 prior to 3.f4 it is considered an improved version of the King's Gambit. The point being to first establish increased control of the center by protecting e4 and adding a second defender of the central square d5. All of this in anticipation of initiating an attack on the kingside beginning with the move 3.f4. The opening is very popular at the amateur level, and playable even by advanced players..

For beginner-intermediate players I also suggest to check out GothamChess (IM Levy Rozman) on YouTube for recommendations and quick tutorials on openings....

For more opening suggestions check out the chess openings tier lists videos by GM Hikaru Nakamura and IM Levy Rozman...
https://www.youtube.com/results?search_query=chess+opening+tier+list
In the tier lists chess openings are categorized and rated in terms of their appropriateness vis-a-vis player skill level - i.e., beginner vs intermediate vs GM’s, etc. Note that in some of the videos (particularly the one for beginner openings) they frequently refer to some openings as "garbage" or "bad" (an unfortunate choice of terms). However, these qualifiers are meant to convey how appropriate the specific opening is for the level of player being discussed, in terms of, for example, how much so-called "theory" (i.e., documented variations) the opening encompasses, or how much emphasis the opening places on positional versus tactical skills in order to play it well.
So, an opening they refer to as "garbage" for a beginner may in fact be appropriate for higher rated players who typically know more of the theory for particular openings and have a more highly developed understanding of positional concepts. For each of the openings discussed be sure, also, to pay attention to whether the evaluation is from White’s or Black’s perspective.
Finally, several articles on suggested openings and other chess topics that may be of interest to the improving chess amateur in my blog....

Best for beginners and world champions alike: defend 1 e4 e5 and 1 d4 d5 as black and open 1 e4 as white.
Basic three move Colle followed by C4 for white or the London System for white and French or Pirc for black.

I have played right into the fried liver as black and my opponent didn’t do the *forced* Knight to g5 and they play the pawn to c3 on the knight move or they might play pawn to d3 on the very knight move.

My main recommendation would be the Colle-Zukertort:
It doesn't have much theory - the Colle Zukertort relies on the player's understanding of its attacking plans and ideas. Usually you will aim to play Ne5, f4, lift the rook over to h3 and together with the queen and the two bishops, you crack open Black's kingside and deliver a simple checkmate. The more you play it, the better you will understand it. Here's a video to get you started: https://www.youtube.com/watch?v=UIL2jF26gjg
It's very good because as a 700 you shouldn't prioritise opening theory, instead you should focus more on your middlegames, tactics, and positional understanding. Pair that with this solid opening weapon, and you should be able to improve your rating.
