Getting 8:1 with two overcards I think I'd like to continue. So I think raising to drive out the SB and get it heads up with the thief is a good idea.

The great thing about this board is that you can be pretty sure the thief doesn't have a 2 (he raised preflop), but he can't be so sure about you (you were posting blind). I think it's likely that if he calls and checks the turn, you might take it down with a bet.

If he 3-bets you on the flop, you've got a problem. Against an unknown I'd probably call and fold the turn UI.
