Cbet can be classed as a bluff but it's more an information gatherer!
I you get flat called off a Cbet you need stats on the villian to be able to Cbet turn!
If you know he will call it down with any pair any kicker then a CBet on turn has no value (unless you have hit).
If you know he will strt/flushdraw with T9etc and you have AK then a cbet has to be done otherwise you give him too much value.
Without info on the player I don't think you can get enough call stations to fold.
I can remember when I first started playing.
My logic was "I've already put money into this pot and I want it back! You are just betting to scare me off!"
It took me a while to understand why a villian holding AK on a 3Q8 7 Q board was calling me a Donkey when I called his Bets when holding T3off!
If you flip this and say Villian is holding AQ then I'm paying him off with T3!
