A few C-betting situations

This board is a good place to cbet when in position. An ideal flop would replace the J with an 8, but it still works quite well. I do make my cbet here a bit smaller than normal due to the fact that this villian has shown he will call a raise with Ax or Kx from the blind, then c/c any pair. Yet he folds to most cbets.

I just came off of losing a big hand prior to this, and made a bad cbet OOP possibly steaming a little. Just have to make sure to let go in spots like this as I did.

It should be quite obvious that this is a spot to not cbet. (probably not even a good spot for a PFR)

This is a spot that I don't cbet due to the villian. He plays a 45/10 game and folds less than 30% to cbets. I'm ready to just give up here. Remember that all good or bad moves can be the opposite with a different type of opponent.
