I think it depends how beginners learn openings. Learning without understanding is useless. If beginners are interested in openings I advice them to learn a basic opening repertoire, 5 to 6 moves, not more, but also some to check some whole games with the system.
I explain them the difference between 1.d4 and 1.e4. Usually I show how to play against some common mistakes in the system they like (QGA / Damiano Dfence), and show opening principles using some interesting games, from Max Euwe’s books or from the classical Logical Chess.
Aftermthey decide which system they want to play, I give some suggestions of opening repertoires, usually from Chessable.
But I have to say that most beginners are not very interested in training. The few people who really want to improve I show how to analyse own games and give further recommendations on books (tactics, endgames).
In my experience people who invest in training will improve faster, even if they train only 20 minutes daily.
… DO YOUR DAMN RESEARCH! Why is it that you refuse to do that????? ...
I do not take instructions from you because, for now, it seems to me to be sufficient to call attention to such things as your numerous posts and the number of times that you have reported specific results from your own research.
