I think you need to raise more on the flop, it will give you a much clearer picture of what you're dealing with if he calls. Very often, this is some sort of ridiculous bluff that bad players will do, and they'll just fold to your raise. However, given the action, the turn lead from this type of player means he as something, either a flush that he doesn't want to scare you away from, or a 5 and he's scared of the flush. Either way you're beat. I frequently find myself calling down these tiny bets to see what the hell he is doing this with.

I also like the turn raise suggestion, as you'll be able to fold on the river with much more confidence (Is that the right thinking Big Jim?).

You're definitely beat by the river.
