Its not the question to fold or not fold here what Im wondering. Im curious about some advice playing this hand from the beginning. Was it better to bet on the flop or not bet on the turn and maybe call a bet if one was made against me?

Villain is a tight aggressive player who is not shy of a steal attempt now and then.
