A6, Turnplay

[Trix]

I openraise on the button in a 5 or 6 handed game.
I´ve been running good and getting good cards, so they probably think I raise too often and bet too often, though I´ve shows down some winners.

BB who is like 50/10, but pretty lag calls. He can semibluff CR the turn multiway and stuff like that. Overplays too. He can slowplay too, so he isn´t easy to read.

Flop T92r, He check-calls.
Turn 8, same suit as the deuce.

I´d like to know how often I´m ahead here.(Just estimate some %)
If I should check or bet and what to do if he check-raises and if there are any rivers you dont call if you check it through.
