I would have re-raised the minimum pre-flop just to make the others nervous (CL sits down in SB and re-raises a busy pot).
Amiller might have a hand but surely Boutthat isn't going all in if he's got you beat. I mean, what's he trying to protect? If he's got AJ or JJ he's surely going to call and keep you in the pot. If he's got AK, he's surely got to re-raise pre-flop and so the only hand that scares me is AQ.
As Doyle says, I'm not going to second guess myself here, especially when a beat doesn't leave me crippled so for me it's an instacall.
I presume, by the fact that you've posted that he did have you beat. That's poker!
