Looks good to me. i'm guessing a low pocket pair hit his set. but anything's possible. 99 is another likely holding. don't know why they wouldn't fold that to your aggression though. maybe a slowplayed AA through JJ? I could see an A with a paired rag hanging on as well, hoping to river the ace.

36 is unlikely but anything's possible at party sng's. how fishy was the guy?
