A shortstack, a call, and I have an overpair

[thac]

Villain is 21/13 over 600 hands, they're all datamined so I'm not sure how he plays, but he's on quite a few tables.

Is this always a call/shove? I'm 100% certain I'm ahead of the shortstack, I'm not sure if villain will 3-bet 99-JJ against this shortstack.

Villain called relatively quickly, but I don't know what he does with any of his hands so it's not really applicable.

So, I'm torn between shoving and folding.. I can't see calling here ever being good due to the wetness of the board, but I think he isolates (because I would) with a draw.

What's our line SSNL?
