@ $10NL I can honestly say that an all-in is just as possibly AK or JJ as it is AA. Never fold KK to an all-in at these stakes unless you have tracker and know 100% for sure that this is AA. The fact that you posted this hand tells me that you weren't 100% and that means never fold KK at 10NL. I have seen all-ins preflop even at 25NL that are AK and even QQ.
