Basically...if you have to ask "should I fold KK pre", the answer is no.
I agree with this.
But as you get more confident in reads you might actually pick spots where it's correct to do so, instead of just being a nit who routinely folds monsters to any sort of aggression.
I'm not the kind of player that actively tries finding spots to make huge laydowns. In my career ( > 1 million hands) I can likely count on one hand the amount of times I've intentionally folded KK pre.

I agree with the second part too, although I'd prefer to avoid talking about 'reads' and instead talk about weighting hand ranges. Like people make the argument that "they could always have AK, KK, QQ so that's why you can never fold KK preflop". Well if those were weighted equally, that's correct. If it's weighted something like 90% AA, 5% QQ, 5% AK... we have ~24% equity vs that range. It's very rare, but *NOT DIFFICULT* to come up with a situation where this would apply.

Yes I understand I omitted KK from the above range but that's only because I'm lazy. If we have KK, there will be one possible card combo remaining for the other KK (as opposed to 6 for any other pair). And if the context of this dicussion is even going to be relevant, we'll have to figure that each combo of AA will be more likely than each combo of KK, followed by QQ and AK or AK and QQ.

Basically, this is one of those things where there's far too much debate and thought put into it for far too little return.
