Doing some of the 'ol 2NL multi tabling, and I faced this really weird spot on the river.

I'm CO, full ring. UTG and UTG+2 limp. I've got JJ, and I reraise to 6x to iso one of the limpers/charge stupid hands.

The SB flats, UTG folds, UTG+2 calls. Pot = 22BB's.

Flop is pretty favorable.

This is the functional nuts, since QQ is probably reraising me. Checks around to me, and I decide to size larger to charge flush and straight draws. I bet 11BB's. The SB snap folds and the limper calls.

The turn is a little bad: 8s. Brings in the straight draw, so when he checks over to me I check back for pot control. He's definitely calling with probably any queen, QJ, Q7, Q8, 77, 88, and flush draws. I think that most of these hands are not limping pre. Then of course I'm probably going to be facing a reraise from 9T, which is going to be a difficult position.

River digs another hole for me. It's an off suit 10. Any 9 now hits the straight. All of a sudden he over shoves all-in. The pot is around 55BB's, and he pushes in 110 BB's.

I couldn't bring myself to call. In hindsight, I know that a lot of fish like randomly shoving with hands that they slow played- usually sets. I think he has a lot of 77/88/TT that think they can just shove. Based off the play, I think he's too bad to do this with missed flush draws. I think that if it wasn't just one card to a straight, I would call. It felt like he was either slow playing a set or shoving the straight, and I think for the pot odds, he's showing up here with the straight much more often: largely because I think he'll realize that one card brings in a straight and will be much more conservative.

The fold is certainly exploitative, because strange OOP shoves at these ranks usually always have it. Was kind of a disgusting spot, and while usually when I'm multi tabling, I'm happy to sigh call, this one felt like I could fold. Thoughts?

Flop bigger bet and turn bet improve only 10-9 and 10-6 is not part from his range except if he is whale..If you check back you give free card and you dont want 9,10 or d is ~25% for that cards who completes flushdraw one card str8 and dont improve your FH so bet turn all day ..fold otr..

11BB into a 22BB pot on a very wet board isn't big. I'd probably go 16-17BB.

Checking back turn is lighting money on fire. It's really bad.

On each street respectively, bet(more), bet(never check in this spot), shove.
