I will raise a little bigger (4xBB is my standard raise so I tend to do 5-7) with JJs depending on the number of limpers already. I do vary my raises enough to get away with this.

What I'm really hoping for is for someone to raise first so I can reraise and isolate. In early position on an aggressive table I may even limp in the hopes that someone will raise and I can reraise them. If no one raises then at least I haven't invested much into this pot. So if overcards come out I'll just check fold.

It's a strong enough hand to feel confident in and therefore you make them look bigger than they are.
