The opponent is unknown. He's playing 4 tables of zoom, so must be a reg.

So I was thinking about turn:
Do you think I should barrel to extract value from Tx, QJ, some combos of 89 or 87? Is it likely that he can bluff reraise me with one of these hands? Or is it an easy fold if get reraised?

River:
If I barrel the turn and the river is blank, is an average reg going to pay me one more street with worse hand? Or just check/fold?
