They don't make it easy
Casino card rooms, particularly ones that have nearby competition gain more customers when the jackpot size gets large. Therefore, they tend to make it fairly difficult to score one. At my local card room, Ameristar Kansas City, the jackpot has recently been changed to Jacks full or better. The catch is, not only do you have to use both hole cards, you actually have to use one of your cards to complete the big part of the full house, therefore, If you have a pocket pair on an A,A,A board, it would not count. Between this, playing both cards, qualifying pots size, you start to wonder if there are requirements for which way the wind is blowing. They sure don't make it easy.
