Call the preflop reraise and play some poker. I would put in a big CR on a raggedy flop and probably go broke if I ran into AA. But I really hate the small 3-bet preflop. I don't think the stacks are deep enough to put in a serious 3-bet (around $18-20) and still have room to get away from your hand. As you played it, it's tough, but I think I'd call here. I remember my first $100 pot (at 50NL) was when I had KK all in preflop. I was so sure I was up agaisnt AA, but turns out he had QQ. So without a read, I'd have a tough time folding here. IMO losing 90BB with KK all in preflop is not a leak, and if it is, it isn't a major one. But getting back to my original point, I like calling the $3 reraise preflop. It allows you to stack lesser hands, and at the same time you still lose your stack to AA.
