Hello,
villain is an unknown reg looking guy, after 15 hands he was 20/13 w 0 wtsd
That's not much to go buy, but he might be scared easily 
Anyways I was thinking that his 3b calling range MP vs CO is something like 99-JJ, AQs, maybe AJs(AK is mpore often a 4bet OOP, no?). My percieved range should be very strong so he should be able to fold his Aces
I am not sure about this one though
Hi BotiaKiraly
That's too small of a sample to make bold assumptions 
Given the board texture it doesn't make sense for us to bluff much so there could be a good chance that they make a hero fold and lay down AQ/AJ.
But the better question is why bet the turn to begin with? Or did you make a plan to bluff 3-streets?
I like 3-barreling with little equity when we have a bit more info on the player.
Why? Because a 3-barrel with little equity requires a lot more FE than a 3-barrel with equity.
And on top of that you are targeting a stronger range. Why stronger? Because it's a 3-bet pot and you want him to fold TP.
