Hey. I just downloaded the free version of Pio too see if I could get something interesting out of it. In the first tree I built (actually was already preset, I just added some bet sizes) I already don't understand some results. For example:

Why would I want to check/fold a flush draw vs 55% pot bet, or why is that a good strategy from a game theory perspective? Am I missing something from the settings or what? Sorry if its a newbie question, first time using this program
