made trips on turn lead out and opponet shoves $50nl

[demon102]

Villian is 85/17/3.2 over 35 hands, at the point of this hand I prolly only had like 10 hands on him so stats dont matter to much. I know I made a small river bet here and I dont even know why I did that. I feel like the way he played it was super strong, it could just be some other random trips here and if so I should call. He shoved pretty quick after my bet so I started thinking he could def. have a fullhouse. Now Im just not sure what to think since Im adjusting back to playing fr agiain. So what do u do....
