»Opening don't matter. They don't matter at all. You can play a3 on move one, Ra2 on move two and if you're 1500 playing against 1500 it's irrelevant.«
That's not promoting opening principles at all.
clearly a hyperbole, though.
Of course it is. But he undermines the concept of opening principles in the same time with this hyperbole.
He was not promoting opening principles in that video. He was saying that opening study at that level is a waste of time. Again...he is right. You can play 1.a4 and win at that level.
No. He did say openings didn't matter, he didn't say opening study didn't matter. You seemingly didn't get that distinction after all.
I think you guys are overanalyzing finegold's comment. It's not like he took the time and effort to prepare a lesson on why openings don't matter. He was distracted and streaming, and trying to find the little distinctions just seems off to me.
I think what he meant was just that learning theory is not a great use of time.
Opening principles is not the same as opening theory.
