I was thinking about making a thread just like this, guess you got there before me
Playing the same stakes and going for supernova as well.
hand #1, difficult spot, really don't know. Maybe bet a little less on the river and fold to a raise, depends on how your image of Villain is.
hand #2 I think it's a pretty easy call, don't think he ever have a good hand, and if he have something like KQ** you still have the equity to call the all in.
Good luck and subscribed!
