Villian is generally a very straight forward player, not bluffing in a ton of spots that looked good with the bottom parts of his range.
He was playing 30/23/8, cbetting flop 54, turn 50, river 55.

I don't know how you break down the hand but generally in my head when this 8 pairs I really assume that his minimum value bet on the river is going to be KQ here and sometimes that is going to check back, it also was a decent sized bet. Also as far as bluffs, a fair amout of them seem like they would give up. I don't dominate any of Villians value range.

Should I just end up calling on river with an 8 and letting the rest go? Should I x/r Tx on the river? lol.
