1/2 3bet AK oop and hit OK flop

opp has a half stack, playing 24/8/1.3

Flop SEEMS decent, now how do you approach this hand in general, do you prefer FLATTING pre and WHY. on the flop I think betting isn't great because I think we're only getting called by hands that beat us like AA/KQ/AQ etc

I thought when he bet the flop he can have an underpair such as 1010 or JJ here and if I bet weak he'll have to call. I'm not sure if TJ is ever in his range so the river didnt seem that scary.

what do you think and how do you approach this one?

overall it seems like you are levelling yourself in general. Try playing a bit more straightforward and ditch some of the FPS

cbet flop $20 or at least raise him to $20 on flop.

Ok I don't really understand leveling, how am I doing it and what should I do differently.
in this spot I'm not trying to slow play, I don't really have an amazing hand here due to the board texture, i'm really only getting a little bit of value from hands like 1010/JJ etc I think.

If you make a small CR on this flop are you getting it in or folding?
can anyone make an arguement for just FLATTING pre?

what would you GENERALLY say about someone who is playing a decent amount of hands pre but NOT raising them like this guy who is 24/8 ?
