why wouldn't a noob learn openings? I mean you don't need to learn them tbh. Just play and you stumble into openings, there are limited possibilities.
the short answer, noobs(<1000) dont play the moves people study, therefore it is a waste of time. You can really just do puzzles and play and that goes pretty far. when people say "learn openings", what they mean (or at least should) is when do you learn variations in depth(beyond a 10 min video). the answer to that is when your opponents start knowing moves AND that gives them an advantage over you. imo if your still ok out the opening, tactics and endgames are more worth it. for me this happened at ~1300-1400. and even then, you dont have to go out like 15-20 moves, just like 10-12. imo of you arent losing out the opening, then you know enough.
