Hand 1 depends on how much you like getting all in as a slight dog in exchange for an overaggro image. If you're really worried about never getting it in behind then play it slow, more like hand 2
Hand 2 depends entirely on villain. if he's bad and shipping it w AK or something ridiculous. Otherwise I'm torn. I probably fold more than 1/2 the time if villain is decent but it depends on flow of the game. 33 is a likely holding for him.
