I've been involved in only one but I did have the winning hand of AAAA10 vs AAAJJ. Requirements art the time were aces full of 10's or better beaten by quads or better, both hole cards had to play. This location now has two separate BBJP's. Aces full of kings or better beaten. Three aces can't be on board for it now as it was in my case. And a quads over quads. I was in the casino a few years ago when that one got hit for nearly $400,000. I was on a "good" (if you know what I mean) UTH game at the time.
