2NL 6max - KQs in the SB vs UTG+1 TAGG

opp is 19/19/4AF/83%cbet over 25 hands

Guess pre could be a fold here OOP? BB is passive and 0%3b so I am not worried about a squeeze here. His range 66+,A8s+,KJs+,QJs,KQo,AT+

Flop could also be a fold but I got a hunch from his timing and bet sizing so I decided to call, with a plan to check most turns and fold if he fired again. (Mind that this site has a 1/2 pot and 3/4 pot button, so he had to enter his 2/3 bet manually). I think he probably does not cbet his hands that have potential (seen him check a flop where he was PFR with two overs and a gutshot), so he would maybe not cbet KQ,KJ and FD's.

Turn comes the Q and I hesitated to bet out, then hesitated to raise his small barrel. Decided against because if this is indeed weakness, I would most likely not get value when I raise, and if it is a suck in bet, then I am crushed.

The Tc on the river is probably the worst card in the deck. c/f standard?
