Hero call?

Villain here is taggy and I have some history with him but this is the 10th hand in the session. Overall he is very solid and capable of making moves on certain boards thinking I have a weak range, etc. Flop I think is a very easy raise kind of board for him which involves air because, in my opinion, he doesn't have any pair here unless it's 77-99. I think he just calls with other pairs/sets, but I doubt he has a low SC pre because "most don't call those pre from my experience". He could be different, but I didn't think so. So yeah I b/c raise for value imo, call turn because I don't think that card changes anything unless he had 87 which he could def. be semibluffing with. River he bets semifast and I really think I have him...how bad is my thinking?

How often does villain 3 barrel with air?

100%

but to be honest he does it a lot when he thinks I have a weak range.

If he's three barreling a lot I think I'm looking to trap with stronger hands. I'm not sure how I like playing marginal hands like this. If he has a wide range there's still a very good chance he has a better piece of the board than you do.

The more I look at this hand it looks like he CRed with a 3 or a 5 possibly with an ace or a 6 as the other card. I think I'm folding turn.
