Villain looks like a reg.

I find this spot very tough and need some help with how to proceed here. My range is quite capped and should also be perceived as such which makes this a perfect spot for villain to overbet and overbluff. Now, I wonder, would you expect an unknown villain on anon to really overbet shove here for value or will he be making normal size bets for value and shove as a bluff?

I understand the vulnerability of my range, that's why I should also have 88/99 on the river as well. But still, I believe I am going to be overfolding on the river by quite a margin if I only call my sets there.and I hate the feeling of being exploited to the point where villain can auto shove any 2 on the river on such low board.

How would you approach the whole hand?

Do you ever barrel turn?

What's your river calling range?

What do you think villain is doing this with for value and what he should be doing this with for value?

Do you think it's a solid strategy in villain's place to overbet shove here any 2 that don't beat overpair on anon tables against field?

I believe TT is one of the better bluffcatchers, better than KK-AA where those two hands block overcard bluffs.

The more you write about dealing with this type of boards in similar spot, the happier you'll make me.

Cheers!
