I think im just shoving river. You have to call if he bets and he may call an all in with hands that you beat but check behind if checked to. I think your flop and turn bet really screams at least 2 pair, but his stats dont come off to me as being a very competent player so i wouldnt give him much credit here. It looks like he may have had a T and then picked up the flush draw on the turn, but he really could have anything here.

Those are large bets with bottom two multi-way and a relatively dry board. I probably bet $1.50 on the flop and ~2/3 pot on the turn. River is tough. Hard to see what you beat that calls a shove. He's a shorty, but is he really felting JT here? If he had the only draw out there, 97, then the str8 got there on the river. I c/c river, even though you're probably beat if he shoves. JsTs/Ts9s are possibilities I guess, but they're not calling a shove, so give them a chance to bluff.
