Is it viable to fold KK preflop against a super TAG with AA?

[Caerbannog1]

Villan 1 is 8/8/~/32
Villan 2 is 19/19/36

I know only a few hands so its a tough decision, at the end of the they could only be doing it with QQ, KK, AK, AA. Am I correct to play here? This is the biggest flaw in my game, so please only post with advice if you are a constant and experienced winner.
