Getting greedy with a vulnerable hand?

[DawnToDusk]

This hand came up and I thought that my line on the turn was thin. Heres what I was reasoning. I figured I could raise here to drive out UTG to protect my vulnerable hand as he has been calling with any two cards preflop. Was afraid that he could have Qh or Kh. Or I could try to go for a call and win one or two more bets. One if he called and folded river after not making a hand. Two if he called the river as well. This doesn't even take into account the CO though, which is another problem. I think its a lil shady. Should I of just raised the turn and protected my hand? I think thats the best line to take, but wanted to double check to see what you guys thought.

Think just calling here is a +EV move?

Well at least your blatantly honest. [img]/images/graemlins/smile.gif[/img]

I kind of figured this was the response I would get. Is there ever a time where one might forgo rasing when they have a flush on the turn? Or on the flop for that matter? Im worried about times when a 4 flush will kill mine if I have a small(er) flush.

if either player has a bigger heart than you, you need to charge them the max. you will also probably get UTG to cold call anyways if he has an A. and CO might 3bet because the fact that he wanst scared of the ace suggests that he probably has 2 pair or something. people suck at poker, espeically at such a low limit, just raise and let them insert more money into your pockets. no need to get fancy.
