Hontas is very tight from utg don't 4bets and folds a lot
His bets are on the small side .... do you think I should call the riv ?
His AG freq are increasing but my sample is not that big
I'm not really sure if he's vbeting KJ and KT because this are the hands that I beat (don't like this 9 on the turn also )

He's not very likely to be v.betting KJ or KT in this spot.
That being said, his line is weighted heavily towards value range.
Fold and move on.

i dont mind c/r'ing turn esp if he fires a fair amount since he bet so small and can actually continue vs a small c/r with hands u beat. obv easy fold if he 3bets turn (and id note he bet small in that spot strong so u might bluff vs a larger bet in future)
if he doesnt bet turns much then yeah u can c/c with a plan for the river

48/65ish looks pretty valuetownish so if he is that tight then u can fold - obv more freq he bets rivers, or if u note he overvalues and vbets real thin then call
