[Cry Me A River]

I'm locking this thread because it is completely useless without READS.

Yes, there are times you can fold KK preflop. I've done it twice lifetime. Both times with bulletproof reads. Otherwise ARRR-IN baby unless you're slowing it down to keep villain in the hand (trapping).

If villains are only ever pushing over you with AA you have bigger problems than folding KK. Either exercise some table selection or work on your preflop aggression, particularly opening up your 3-betting range in good spots.
