This whole debate is really hard to adress simply due to the enormous discrepancy in different opponents' play in these spots. For example, otherwise tight, good players may give you far less trouble then the otherwise fishy calling station that gives way too much action, for obvoius reasons.

I will say this however, when somebody is sitting on my right and open completes, it's pretty much an auto-raise unless my hand is hopeless. At the risk of sounding too arrogant, anybody who thinks they can consistently limp/call trash and then play in a raised pot against me OOP in this spot and still get the best of it... is wrong, dead wrong.
