How bad is this?

[Louis88]

This is a situation that always confuses me. I usually bet and fold to a raise on the turn, but feel like if I do that too much, they will start picking me off with bluffs. What about the river, c/c or c/f UI? SSHE talks about this situation only briefly. Are there any good reads on this subject out there? (When an overcard falls on the flop.)
