OR 44/24 25 hands

pre: Should be ok

Flop: Should I Cbet? I think I am committed against this guy and he doubles up if he is holding an A, regardless of whether I b/c the flop or Calldown Turn and River. But how could I win most from his weaker hands? Bluffinducing or betting? Especially PPs will maybe call the Flop, but fold the Turn if there is another overcard.

Turn: Scarecard. Can I call here? His push does not make sense for me, but I am holding only a bluffcatcher...c or f
