Iopq, you said you'd often check the turn after betting flop, because you're afraid you'll valuetown yourself. I agree with your argument, especially with MPMK/MPBK, although I'm not sure it weighs enough when we're OOP.
Is your plan to c/c or c/f?

If you're c/c-ing I assume you c/f river. I have a feeling I'm getting exploitated very often in that case (but that might not be true, just seems so), because people seem to bet both turn and river very often when I'm giving away initiative here.
Are you confident that the times you do get to showdown using your line nets you more than the 'simple' b/f-ing turn? (simple in easy decisions)

If you do c/c turn, c/f river....are you having a range for c/c turn, c/c river?
