.....not enough money for you to fold

easy call here. he could have a set as easily as a draw.

he called pf with either a pp or two suited cards. this one is a short-stacked idiot.

snap call

I think Villain has A9 or princess peach trapped in his castle.

I'm in the easy call camp. I can see this being a bunch of suited 7/x of hearts combos, A/7hh, possible 9,7 or either draw. You should be good most of the time.

Should this be closer to PSB on the flop?

call...if he coolered you then fuck him
