Villain is 21/18 AF=3, 3B=10% (10 out of 104) CB=67% over 264 hands. He had never 3bet v UTG (0 out of 31 times).

What do you think here ? Would you consider folding ?

Well I block AA and KK so theres only 4 combos left of that, then there's another 9 combos of AK that I chop with. I also block the NFD, so I think AA/KK/AK are more likely also given his PF action, maybe he has KdQd, KdJd. So for calling his shove I need to be right here 30% of the time. If he does this w/ all AA, KK, AK combos and KdJd I have 38% equity and should call. The problem is that I doubt that he will squeeze w/ KQs,KJs every single time and I also doubt that he will shove AK OTT every time. Against AA,KK,AK I have 31% equity and a call is therefore marginally +EV.
