[Closed] TT overpair in 3-bet pot

I may question preflop play, but can't really decide is the 4betting/folding an option here. Thoughts?
Flop & turn is fine. River bet is strange, he may put you on draw and he may have some 9x hands in his range, and unless he's really aggro I think it's often going to be a vbet as you called the flop, and he may have waited for you to bet turn to c/r you. When you checked back he just made a 1/2 pot bet to allow you call with marginal holdings. If board was rainbow I would trust this my story even more.
But I may be cpmpletely wrong with my path here.

Well pre flop i didn't want to 4 bet as I would be turning my hand into a bluff as villians 5bet range is probably QQ+ and AK+ as i had not been 4-betting him a lot. I would rather 4-bet here with Ax or Kx. Im not too sure but I think calling is ok considering the amount of bluffs he has in his range. On the river here it does kinda look like a failed check raise with an overpair or set but it could possibly be a bluff with air to make me fold Ak or Aq I guess.

You say he is loose so I think the call is correct if you have seen him bluff sometimes.

Personally I would take a r/f fold flop line because there are a huge numbers of cards I don't want to see coming and he's not gonna push AQ+, KQ into me that often if ever. But here the turn isn't that bad and he made the river call cheap enough. I would expect most of the times to see them barrel like crazy that's why I suggest the r/f line. Maybe it's just something that works on Rush or is just working atm and that will change.

Hope it helps!

you can play it that way and take safe calldown mode
Against player who has 3-bet me a lot I´d also happy to 4-bet and call shove or play my overpair aggressively postflop
Meaning I´d raise small on the flop and hope he shoves with worse hands, since TT against his range is just too good and I don´t want to see overcards where he is likely barreling again and I don´t know what to do with my tens
