Stats are key. That is if you want to bluff, you should have a decent sample of hands on the opponent. High % of folding on the turn and river will give you more reason to bluff. High % Won at Showdown is also a good thing in this situation. Be careful though, even if they're tight, if their betting has indicated a lot of strength then you shouldn't be bluffing them. E.g. they raised preflop and their pfr is 1% or they bet at the flop and their aggr frequency is very low.

That advice comes from someone who almost never bluffs past the flop, so I doubt its very good. Just my thoughts off the top of my head. I'm a total hud-head, because I play 12 tables, but you can get better reads by actually paying attention to watching everyone play.
