If I do bet the turn, what am I doing to a checkraise? I would probably 3-barrel TT and even 77 here as I'm not worried about getting value bluffed off those hands (whereas with JJ I'm worried TT might), but with JJ I'm not sure how to respond to a turn CR though I'm guessing I have to fold.

Do we like a turn check? Can I raise this river?
