You open 7s6s in CO, BB defends
100x deep
Js Ts 5h flop
Check, cbet, call
Turn Tc

I feel I'm losing this pot way more often than I should be. I tend to not cbet turn too often thinking I don't have much fold equity and sucks to b/f to a check-raise when he has a bunch he can check-raise bluff with. But that leads to me folding to his river lead like always. 

What's your plan here? How does it change if you have A7ss? 97ss?
