I liked pokey's response. But, igore any player that says you should always fold this. Limping is okay if you also sometimes limp with your big hands. And the good players might just a call a good hand they would usually raise with. Of course limping here depends greatly how the table is. Is everyone playing tight? Do people not raise PF enough. Have you limped with a big hand before.
With all that said. Most of the time you should fold. But, if as you can see table conditions permit. Limping is not a bad play either. And even still raising would be good sometimes as well. Know your table and you will succeed more with these types of hands. Just don't make a habit of limping too often so the good players don't punish you for it.
