NL50 & 100, KK becoming a routine fold to all-in preflop vs. unknown?

[Gobias Ind.]

I don't inquire about higher limits b/c I assume those games are played on levels beyond my comprehension at this point in time.


I feel like my KK is running into AA a ton lately preflop and I'm really starting to question whether its a leak to be calling off preflop for full(ish) stacks w/ KK. I asked this question a year ago and the response was to undoubtedly get it in preflop at NL50 & 100.

Do you still feel this way? Do you often find yourself folding KK to a 3bet shove vs. unknown?
