I'm not fond of the flop 3-bet without reads. I won't be surprised to see AA or TT just as often as T8 and A8. I prefer calling and reevaluating the turn. If he's passive, he probably will do a crappy job of getting money into the pot on the turn/river with a better hand. Conversely, if he has a worst hand, he will probably overplay it, as bad players like to do medium strength hands.
