Theory post: KK Preflop in BB versus SB

[Malachii]

You're in the BB with K [img]/images/graemlins/spade.gif[/img]K [img]/images/graemlins/diamond.gif[/img]... action is folded around to the SB who raises to 4x the BB.

Do you call or reraise if the SB is an aggressive player who will raise your BB frequently with a wider range of hands?
Do you call or reraise if the SB is a more passive player preflop who will reraise with a narrower range of hands?

I'll post my thoughts later but I wanted to hear what other had to say first.
