Villian is unknown ( most likely lag but only 25 hands ).

Should I call this or fold? If fold, what pot odds / pocketpair would you call with?
If call, is this also a call agaisnt a fullstacked villain?

Is the c/r OK btw?

Reraise this all day long PF, calling OOP is ugly. As played, I'd fold to the shove against an unknown. If I'd flat called PF with JJ (bad again), I'd probably call here.
