Can I extract more from this flush?

If you slightly overbet the flop the pots 15 going into the turn. Bet 15 on the turn and then the pots 45 going into the river. Bet 45 on the river. This line nets you and extra 21 dollars.

If you think villain can't fold a set pushing the river is a decent option to. It looks like he's in check call mode make him pay. The overbet only needs to get called 1/3 of the time that a pot sized bet get calls to be more profitable so it might be worth a try.

Underbet sucks he'll just call it.
