This event and the alleged dump have been discussed many times over the years here and on onepocket.org. The overwhelming consensus has been that a dump did take place. Why, with these latest threads, several are now vehemently denying it, I have no idea.

In the above link a poster named Lucky_Lew66 says:
"what was so bad about that match,they were both gentlemen and didnt break anything ,when you know they wanted to, hey for $50 K straight in gets to looking tough i am sure, that was a big prize fund for them at that time, they didnt do anything embarrassing in my opinion, nothing that Golfers,bowlers,Tennis players, havent done when playing for big cash."
To which Sjm responded:
"To my knowledge, this is the first defense ever offered for the participants in the twenty two years since it happened, and I expect it will the last.
The players, themselves, were caught having made sidebets on Mike LeBron and the Mirage, reportedly, refused to pay on some of them, and no Las Vegas casino has ever made pool a bettable event again in their sports book. Those who participated in this dump disgraced our sport. Whether disgracing one's sport is embarrassing or not is possibly debatable, but the lack of integrity here is not.
Jay Helfert, tournament referee at that event has posted about how, even though he could see the dump in front of his very eyes, the rules did not give him the power to do anything about it."
Sjm also posted a link to a onepocket.org thread on the subject:

This is indeed an old, sad subject that most would like to forget.
