NL 25, AA played wrong?

[Big Rob Jr.]

I'm only playing at this level because I needed to earn points to get to Silverstar level, I've been playing SNG's since my first deposit two weeks ago. I have alot of live cash game experience, not much online. I have no reads on villian in HJ, this was his first hand, CO had went all in on the previous two hands and lost, and I don't have a read on player behind me (price paid for six-tabling).

Final Pot: $25.85

Should I have just called MP3's AI instead of pushing myself? I really didn't want to play Aces in a four way pot, but I feel as if I might have left money on the table as played. I'll post results later.
