Stars $1050 KK first level

[samsonh]

Villain is Staminga who I have played 400 or so hands with in 114s. He has shown me nothing spectacular in those SNGs but has a terrific record in MTTs. My gut is screaming AA. Am I stupid for pushing here? I could fold and still have plenty of chips. Does anyone fold here? This isn't meant to be a bad beat post, sorry if it comes off as one.
