What do you do on the turn after you semi-bluff the flop? Let's say you get a flush draw (either in or out of position) and semi-bluff and get one caller. The turn doesn't hit. How do you base your decision on what to do on the turn? I assume position, reads, table image, and stack sizes all come into play. Do you have a standard approach, or if not, how do you change it up in this situation?

Edit: Just realized maybe the turn action should be broken down into three variables.
1. you are out of position and first to act
2. you are in position and villain checks
3. you are in position and facing a bet suggesting villain has something
