I see your point penguin and would have agreed with it for a long time.

However this was in part a mix it up play against a player I will probably be playing a lot of hands with over the next bonus. My standard play would be to bet out and if the flush had hit I would have been in trouble.

For what it's worth I won the hand. I did not see his cards as Sun poker is helpfully crashing every time I open the hand history tab. I assume it was JJ or something.
