It seems clear in the article
Here is how it is printed in the article:
$20,000 guaranteed added ten-ball event:
Entry: $70 entry/$30 green fee (plus $20 tour card if not a GSBT 2008 current member)
Field: limited to 256 players
Equipment: 9 foot Gold Crowns
Rules: race to 9W/9L, double elimination, rack for each other, winner breaks, finals race to eleven (win by two)
As a player I understand that the room is taking the beating on the $20,000 that they are
adding however they hope to recoup some of that on food, drinks, and most likely there will be a spectator charge. (We will not argue whether the room owner makes his money back at this time please

).
I also understand as a player that I am paying $100 total to enter plus a $20 dollar tour card if needed. I personally don't care who gets the green fee but I feel that the tournament director will keep that for running the event, advertisement/flyer/mailing costs. And I understand that the $30 is a fee so therefore it does not go in the prize fund.
As far as the added money from the room owner being guaranteed I don't think it will be an issue as the room owner seems to be a big pool fan and played in the last event that Shannon had there. If you want to ease your mind you ought to come to the event on August 16-17 and visit a nice room with a really great layout that I think will be spectator friendly once bleachers are in place. I understand how it is hard to trust getting paid after many players have been burned in the past so it is up to each player to decide if they want to take a "gamble" and play.
I respect Grady's way of advertising his tournaments as $10,000 guaranteed fund
with 70 players, however I think it is harder to persuade players to come to a tournament where they know that the payout depends on how many players are there. In the case of Shannon's event (as long as you aren't skeptical of getting paid) you know that there will be $20,000 in the event no matter how many players. I feel this is just a matter of preference in advertising styles.
If you are concerned about getting paid I urge you to contact Shannon and get his side of the story before we get a nationwide panic of an event that is 4 months away. No need to start a boycott yet guys and gals. I truly hope it is a very successful event for the players, room owner, and the tour!!
