If I'm reading the stats correctly, villain has only 7% PFR and near non-existant aggression. Reraising what was already a huge raise from hero doesn't seem like the type of thing he would do without a very good hand. Unless he's just completely gone on tilt, I don't see A2 being anywhere near his range. I'd put him on AA-TT, AK, and maybe AQ. Also, the fact that it was a minraise suggests that he wants a call. If he was bluffing with garbage, wouldn't he raise enough to have a reasonable chance of getting hero to fold?
