I really think I should have raised the turn. At the time I thought that by just calling I could keep the other two players in the hand on draws and make more on the river if either of them caught. But now I think I would have made a lot more with a raise on the turn. Comments?

Raise the turn and OESD or flush draws will still come along and if they do hit they'll most likely raise the river and you can reraise.

Yeah, raise the turn for the reasons you gave.
LOL at UTG.
