Do not worry about openings. Just play by general principles. Stick to the same opening and gradually build up experience from playing. You can look up the opening after you have played a game. Each time you change openings you lose more. 1...e5, Caro-Kann, Sicilian are all top notch. Pick one and stick to it.
I mean I've been struggling a lot lately. Used to be a caro player and switched to Najdorf. Been tryna play Najdorf and kind of Sicilian Defense in its entirety these days. The ton of theory they involve is really mind shattering! Is anyone aware of any chess books or in that matter any chess resource/method to efficiently and effectively learn openings and build a repertoire? Also how to learn openings without focusing much on memorization and more on understanding? Any help is highly appreciated! Peace.
Little Background:
I might as well be around fide 1650-1700 elo(my peak). Have drawn a 1877 elo OTB, few months ago. In my amateur phase, I used to play e5 as black against e4. Had a lot of success with the system. Then I dropped e5 and switched to c6(caro) just for the sake of learning positional and strategic play as I used to very bad positionally. Been playin caro for around a year now and have built a rock strong intuition in every structure it possesses. Then my friend came into the scene and suggested me to switch from the ever comfy caro to something with more initiative, activity and chances. So as my goal of being a better positional player was achieved, and I wanted to switch to active play, the only system that remained was c5 (Sicilian). And personally I like Najdorf. Somehow the positions that occur in it, come natural to my intuitive prowess. I just need proper guidance to carry forward it's legacy.
