I'm putting the guy on a slowplayed two pair or a set (maybe, maybe AJ). Unfortunately there is someone behind me and I don't know what he has--hopefully not a flush draw.
So do you call? (or fold)

No

Easy fold, you really don't wanna call this raise with an oesd and maybe two tainted outs and the possibility that the guy behind will push.

Get out while it's cheap.
