if a "2. They fold too much." decided to 4-bet, then you gotta start thinking KK+. You also need to relate these categories to their pre-flop ranges - a 9-2 nit is never a "3. They don't fold enough" cos they always have QQ+/AK....
a 26-24 is unlikely to "2. They fold too much"

and if you're asking about 3-betting, you should also ask which category you fit into. And then think about 3-betting ranges and 4-betting. Position is so closely related to 3-betting action that separating the two is asking for trouble.
