Yeah, I reached 1600+ with pretty bad openings that I didn't even know well, and 1800+ with the same openings that I got a bit more experience in, but didn't really study theory on much.
The little theory I did study was useless since my opponents never played into it, funny enough.
And my level of "talent" is rather low - I just focus on tactics and strategy, which are the things that matter in chess, and lets players with completely no opening theory knowledge play at 2100+ level.
but, as far as I can tell, Dan Heisman was open to the idea of picking up a book on a particular opening even if one is not approaching at least 1800-2000.
And that was never, and is never, the question. Your logical fallacy is: strawman!
I was unaware that anyone had granted you the power to decide what questions may be discussed here.

I do not see zac_howland mentioned in post #1.
You do not see the question being asked either, apparently.
My understanding is that it is acceptable for related issues to be discussed.
