Should I lay down KK here preflop?

Villain is LP. VP$IP 42 percent, but PFR% is only 2%. PF Aggro is .86, I have 103 hands on him.

Hmm. Looks for sure like he's got AA. Let me do the math real quick. You've got $89... So, by my math, you've got 64$ left and there is 91$ in the pot... nevermind, easy fold. Dump it.

Although I'm not an advocate of the AA guessing game(especially at this level), considering the stats and pre-flop action, it's OK to dump it.
