Everyday I use pio, I keep seeings spots where the blockers I generally would assume make sense are really not the ones that PIO uses. I really want to understand what the logic is here so I can get better and understand why it wants to take certain combinations as bluffs, or folds or whatever the case is when in my mind clearly another seems like a better option.

Are there any good videos on this or any other ways of understanding why pio does what it does if I'm not so enlightened that i can do it on my own.
