UGH :

He's an unknown nit I'd pretty much barrel any combo draw KK AQ too as he should raise a set. KTs is very much in his range here.

Problem is that I pretty much check fold 100% of my range on the river besides Tx that I don't have that much of, expecting a tight PF stats guy to check behind without a T and not bluff busted FD much, anything else I can do?

i think you may consider bet/folding since you lose so much value when you are ahead to check/folding and he could have a good amount of lower two pair combos as well, its a great card to bluff, and your river check makes you look a bit weak

obv im not advocating check/call or bet/call but i think you can make this an easier spot to play by making a river bet to try to maintain control of the hand on the river instead of ceding the action to him.

i think even betting something small, like $10, would get villain to call more often than not with a lot of his 2 pair hands instead of turning them into bluffs, and block a lot of his bluff shoves to your check

i could be retarded here, but im thinking its sort of like making a river block bet since it would be incredibly easy fold and you could feel more confident that he did indeed have you beat with a Tx

Yeah I like betting 15 here. If you do it with Tx aswell he can't really bluff raise you.
