Villain is 70/14/1.7 wtsd 18%. Does seem to call CB almost all the time though.

Ok, hand is sort of standard (exept for firing second barrel). My questions are below.

3 folds, I raise to 10$ from smb with [Kh]. Villain in bb calls (surprise, surprise!)

Flop [6c][3s] - 20$. I bet 15$, He/she calls.
Turn - 50$. I bet 35$ (I hardly ever do this - see below), villain reraise to 80$, I fold.

I sometimes find it very tricky to be the raisor against these loose players (unless I've got the goods of course!). If they call every CB, then fires half pot on turn (and I fold) then what's my solution?

I guess I could raise less than my normal 14% to stick to the more premium hands (ie not raise A5s OTB, or just limp 33 in CO after one limper). Or should I fire again on turn (like in this hand)? After all this villain only has 18% went to showdown... Firing a second barrel could turn very expensive though (as it did here).
