1) Sit.
2) Sit.
3) Eh... I dunno. This depends on villain. Sometimes I'll raise him. He has less than a PSB here. With 4 aggro factor, I probably just get it all in & sit.
4) Don't like this line. If he checks to me on turn, I'm shoving it in there.
5) I'm definitely shoving here. WTF. It also depends on the turn card a lot. If it's a Q or like a T, then it's a different story than if it's a 2. Too general of a question for a specific answer.
6) Sit.

Well, you answered all of your questions yourself, and I think they are too general to begin with. Your question is based on what to do on turn. This depends on the villain you are playing against (His turn aggression, your reads on him, etc) as well as the turn card. Turn card is essential here. Most of the time even if it's a heart, he doesn't have a flush here.
