Does he have trips or is he just acting like it?

[jsnipes28]

I had kind of been running over the table taking down a lot of pots preflop or on the flop. I am pretty sure he thinks i have some type of AK, KQ, KJ type hand here. This is WA/WB so i figured 3 betting the turn would be bad. Chances are he doesn't have a nine and is just repping it because he thinks i am unlikely to hold one given the way i have been playing. I haven't seen him do anything crazy so he could very well easily have one, but i have my doubts. How's this line, anything you do different? Not sure if this is important but i hesitated for a while before calling the turn trying to decide between calling/raising.(And please no fold preflop one-liners as that is not what i am looking for here)
