First, AA doesn't play well with multiple partners...it doesn't like threesomes. So open bigger like $0.35 or so to try to get heads up.

2nd, I've noticed that people at these limits love to slowplay sets, trips and other big hands. His PF range that you gave him has all of these in it.

Third, the check, check, shove line is screaming that he's got a big hand or trying to bluff you out.
My thinking is that he's been sitting on trips from the flop or completed his shitty flush. I'd fold.
