I would simply call. The main problem with raising is that I cannot call a reraise, so it would make no sense for me to raise if I have no guarantee that everyone will fold. AJ is not a hand to build the pot with.

It gets better. With a hand like AJ suited on the button, I can even call a decent raise from the SB or the BB since I'll have position after the flop. If SB or BB raises an enormous amount, then I'll give credit that they're not just squeeze playing and fold. If SB or BB raises for me, I'd be happy if CO calls because I'm probably not in too good shape but I have great odds and position. If CO folds, then I'm still happy because I have position heads-up with AJ. If CO reraises, I'm STILL happy because I can now fold with no regrets. If nobody raises, I'm STILL happy because AJ suited isn't that great to begin with and it plays nice multiway.

No matter what happens, it can't go wrong. I'm limping.
