give up on the turn?

Party 5+1, about 5 minutes before the first break. UTG+1 has been fairly loose so far...most of his stack is from skillfully flopping trips a couple times. He's at 40%VPIP through 40 hands. I'm nearly certain that if I bet the turn, he's going to push. A flush is an entirely possible holding, but I haven't seen him play enough to guess as to its probability. What should my plan be here?

If he is as loose as you say, I have difficulty getting away from this. I fire my pot sized bet. If he comes over the top, I likely call. There are too many hands that a loosey may do that with, for me to give-up a BB special. If he was tight and came over the top, then I might consider giving it up. I don't slow down on the turn though. Heads up, you are likely ahead. Multi-way I would worry more about the flush.
