6/12 live-betting into a PF raiser with less than top pair?

[mrcunningham]

9 handed, Saturday night, average of 4 to a flop, button is 35ish ethnic Chinese that speaks Chinese, if that makes any difference to any of you, who has been fairly quiet in his 30 minutes at the table so far.

I limp Ad5d UTG+2, button raises, Bb and I call,
F: T52d
BB check, I bet, button call, BB folds
T: 7
I bet, button calls
R: 6 (no possible flushes)
I bet…

Thoughts?
