Common problematic situation

[DrSavage]

Let's say we are SB and raise KT, tough lag in BB calls. Flop is something like 278 and he calls a bet. Turn is a 9. What is the best line from this point?
This is the board on which continuation turn bet will get raised a lot, by pairs draws and assorted garbage alike. If I check I am also basically guaranteed to see a bet. I'm usually lost in these scenarios with a hand that has some showdown value, a decent draw but is guaranteed to face agression.
