Shove the river?
Well I guess it depends if we think he can fold his overpairs because at this point he only has PP in his range 33+. Only pb is that I think ppl tend to call a lot when there is a missed FD and I think he would call a shove here. In his shoes I would hate my life if I had to call with less than AA here though
Villain is relatively unknown only 60 hands. So far he played 20/13, 3B 1/29

Hero ??
I would shove on any diamond, heart, K and possibly Q. Not sure on total blank.
or 
is a shove, but I'm not really sure I'm shoving anything else. Maybe 6 is a good card, we can rep some gutshots. I'm not really sure we can shove Q or K for value. His value 3betting range is something like JJ+,AQ most likely and he continues only with few bluffs that hit something after our flop c/r. Q definitely gives us a better bluffcatcher, not really sure about K, it think it's close if we assume he's not folding AK on the flop and turn.
) and there are no more cards to come. Problem is as everyone says he just isn't going to fold so as it's zoom and no-one is paying attention cos they are frantically clicking buttons I'd just let him have it and be really tilted if he somehow has A6 of diamonds.
