He didn't reraise preflop so no AA, most likely 8x, and if he indeed has A8 that would just suck but I would get it in although not too happy about it ofcourse. Does he raise his draws? If so he might have a worse flush. I also noticed his stack is 500BB, that combined with these crazy stats makes for a guy who will go for thin value expecting to be paid off by people who are riled by his constant aggression, so you have a very good chance to be ahead here imo.
