Well I can't speak as an expert, but if it's folded to me on the button I'm raising any two 9 or higher, pocket pair or A. Maybe decent suited kings.

Actually if you have HEPFAP, there's a section on shorthanded that gives a guide on how to reraise w/ about 35% of your hands (and what to reraise with) if you're HU with someone who raises any two. You may as well just use that (I don't have it with me or else I'd share)
