I check-raise the turn again since the only hand you are behind now is QQ or AQ and I doubt he caps AQ. Then again I don't know what hand he 3 bets you with on the flop unless he's being retarded with KK. Or the deck has 5 Aces.

If you can fold to a 3 bet after a check raise on the turn then check raise the turn. Otherwise bet-call the river. I would throw a tantrum if the river got checked through.
