It's pretty simple, really. If you've got a player who's calling down with sub-par hands on a regular basis (ie a calling station), then value bet your marginal hands, and avoid bluffing
Usually you would only value bet your strong hands vs a player who won't call with marginal hands since he'll only call you if he has you beat, but if you've got someone who'll call with crap, then you can value bet a wider range of hands.
As for bluffing, I'll loosely paraphrase Brunson: "it takes an idiot to bluff a calling station". No point in bluffing someone who can't let go of middle or bottom pair.
