This is where pre-flop stats are very imporant. If someone has reasonable TAG stats, they are usually calling your 3-bet with only AK and good pairs. On a low flop, they are not folding most of their range (overpairs).

Actually, this is where having some idea of villain's read on you is very important.

Does villain know you are a thinking player? Does villain know you are 2+2? Does villain see you as nitty or more "creative".

Most players play very straight-forward in 3bet pots. If they have KK+ or they flop a monster, they want to stack off. Otherwise, they don't.

The exceptions are few - LAGs and 2+2'ers. Particularly 2+2'ers playing each other.

If he thinks you're in the first group, and you'll only double barrel/push with KK+ then he's folding TT/JJ/QQ. OTOH, if he thinks you'd double with TJ/AQ/AK/QQ/JJ then his calling range is going to be much wider.
