Don't think I ever fold KK preflop at these stakes tbh. There are too many people willing to get it in with AK, QQ, JJ, 10-10. Plenty more combos we are ahead of here then behind to. Just a cooler if he woke up with bullets.
No this never a fold. 100bb vs 1 player I would never fold. You can start thinking about it when you get deeper, there is more action like cold 4bet and 5bet etc infront or if the positions might suggest and any of the previous is true.
This is the age old micro stakes question and unless we're approaching >200bb stacks and/or some freak nit territories the answer is as always a resounding - no.
