This is a discussion on Three betting light vs three betting heavy? within the online poker forums, in the Cash Games section; What is the difference between three betting light vs three betting heavy?
That depends on the villain you are facing. Generally speaking you want to 3bet light (bluffheavier) vs people who have a high Vpip and/ or a high Fold to 3bet percentage and tight (valueheavier) vs villains who don't.
As for a general strategy vs a vacuum I would always balance my 3bet/4bet range with bluffs, as if you don't you're opponents will have an easy time reading you're hands.
