I've recently started to pay more attention to villains' reactions on cbets (fold, call, and raise cbets).

Now, if villain folds 50% or more, it's straight-forward.
But how do you handle these types of villains (OOP and in position):
a) raises cbets often (30%, 50%, or even 70%)
b) calls cbets very often (50%+)

Are there any general strategies against these guys or does this depend a lot on other reads? I seem to make my biggest mistakes in HU situations against these types.
