Ok so this hand came up at the local Horseshoe yesterday. 1/3 NL. I raise to 11 from EP with JJ. Tight, very aggressive villain makes it 30 from MP. I call, flop comes AJ3 all hearts. I check, he bets 50. I figure he's either got...AA, KK with Kh, or AK with Kh. Maybe even AQ with Qh tho whether he'd reraise me with AQo is questionable. Anyways I raise to 125, he immediately shoves. He then declares that he has three Aces. I ask him if he really does. He says yes, shows me them. I fold of course. I had about 90 more and I think he thought I was on a draw and didn't want to gamble with me.

I was thinking about folding anyways because I really thought he had AA. He saved me the trouble though thankfully. I was wondering if someone could help me figure my equity against his range to see if a fold would have been a decent play had I not seen his cards? Thanks.
