Thanks for the response skp.

I probably shouldn't have posted under your post. I was replying from the perspective of OP not if I were UTG. I would want it Hu with UTG. Difficult to say if that's best achieved with a flop raise or turn raise - depends on Button's hand and tendencies. But since I don't know either, I'm usually raising the flop to get it hu with a likely badly dominated UTG hand.

If you just call the flop you're giving button 12.5:1. That's exactly the odds he needs I believe to chase any pair. If he has a pair that could make a runner runner straight or flush, and
1. he would call two on the turn once picking up that straight/flush draw or
2. utg doesn't bet the turn and he gets to see the river for 1 bet
- you're losing money letting him in on the flop (if my math is right).
