I bet $2 on that flop because it's pretty drawy and I want maximum fold equity. The turn card wasn't particulary good because it completes a few straights and puts a flush draw on the board that a tricky player might chose to bluff with outs. The c/c c/r line usually represents a pretty amount of strength. I think I would have checked behind on this turn, confident on calling a bet on the river, because he would stab with a pretty wide range considering your description.

BTW: I fold here, because you can be pretty sure to play for stacks on the river and I'm not too confident about the value of your hand on this coordinated board and the huge amount of suited connectors that villain has in his calling range and his traditionally strong line (which doesn't necessarily mean anything).
