Sam, I disagree.
Following this story here is the best quote about the corruption of tennis and the ease of match fixing as it relates to pool.

"Well, if you were going to invent a sport which was purposely designed for match fixing. The sport you would invent would be called, 'tennis,'" says Richard Ings, former head of the anti-corruption program at the Association of Tennis Professionals (ATP). "Tennis as an individual sport only requires the participation of one individual to fix the match."
The opponent doesn't need to know. Or the umpires. Or the fans.
"And with so many matches being played around the world, the opportunity for fixing matches such as this is quite widespread," he says.
I don't think anyone can fail to see the duality between pool and tennis in this regard.
The fix is in.
