[Seven of Six]

I am hoping the gurus here can help me out. I play at a site that offers a bad beat jackpot and here are the rules:

Valid for real money Texas Hold’Em games played at Bad Beat Jackpot tables with limits $0.50 / $1 and higher.

The losing hand must be ‘Four of a Kind’, Jacks or better. Both hole cards must be utilized in the winning and losing hands.

Four or more players must be dealt into the hand.
Players sitting out the hand do not qualify for the jackpot.

What is the probability of this hitting? What do you think about the winning hand needed. If you were to set up a bad beat jackpot that could be realistically hit, what you have the qualifying hand be.

My thoughts for the hand would be ACES full of Jacks beat.

What do you think?

Thanks in advance
