I'm a TAG. If I'm in the BB in a 3 handed game and the Button raises, I'm 3-betting a metric [censored]-ton of hands.

So, you're beating decent range of his holdings. But, like I said, it depends on how the TAG has been playing/running. You can't let yourself get pushed around 3-handed... you need to call down with A-high somewhat frequently.
