Yup, raising or reraising trying to "isolate" the raiser heads up. It doesn't really refer to strong hands that you'll 3-bet with anyway, the phrase is reserved for seemingly marginal holdings. You need to have a reason that this situation is a lot better heads-up than 3 or 4 handed. Some such reasons include [] he's a maniac and if you make a pair you can get several more bets in as a big favorite [] you know what he's got or he's real predictable letting you outplay him seriously later [] the natur of your hand is such that it loses a lot of ground against more than one opponent.

Everyone folds, the button calls, the assertive SB raises (he probably doesn't have a pair), and you have 66 in the BB. You should 3-bet to isolate the SB.
