I open UTG, SB and BB call. C-bet 50%, both call. Turn, I barrel for 2/3pot. BB is a tight reg, do we just let it go?

Yesterday I had such a strange random experience, that it took me a while to recover, not because of the size of the pot, but because of what has happened. So I guess you know this shitty feeling when some one hits quads against your full on the river, or goes all-in pf with KK vs your AA and you lose. It sucks, but that is explainable. What happened to me was completely different. Please look at the hand (it is 1-2$) and share your thoughts. So the guy here is playing for a while on the table and is up like 2-3 buy-ins. He opens button, I 3-bet, I bet half pot flop, he calls. I bet half pot turn looking for hands like TJJK or TJKK, he calls. River I do a bet of 50$ and he clicks me bet 100$. I am calling out of curiosity already and because the hand doesn't make to much sense. And here is the hand. Really felt like I was scammed.

Sticky short stack db pot on the flop, we call. Turn, facing the shorty all-in, do we call or jam?

Table starting at PLO200. FLOP: First of all solver often XB these kinda boards, but since people dont XR nearly as much as they should i think we can get away by over cbetting. TURN: My usual size for turn when the nuts dosent change as we just saw a call on the flop is to pot. Would obv not be super happy if got XR but can easily call and evaluate river. River: Now for the sake of the post. We heavyli block the folds, but will never win if we XB. How would you guys approach this river, and what is your thoughts. I think going something like b10 to simply fold out similar hands + random board pair might be the better option if we decide to bet. A similar hand in the solver XB 29%, b50 15% and pot 56%. Not sure i like the pot option in this line.

Here's the situation: I RFI the Button with KJ776 Double-Suited and call a 3Bet from the Auto-Straddle (Opponent has loose preflop stats but we don't have too many post flop reads yet) We go to a flop at an SPR of 2 Flop comes T76 Rainbow and Opponent Checks to me. I make it half-pot with Middle Set and Call when Opponent goes all in. I still like betting the flop, and I don't think I can fold to the jam afterwards. I wouldn't mind some second opinions though :) Opponent ended up having Top Set
