I always thought it was called Dice Control. To me this is the stuff of legends. I never really believed it was possible but once heard a convincing podcast otherwise so who knows. I figure for every person who could do it with a most marginal edge - there are 20 others who hopelessly fail but believe. That's probably being conservative. Who knows if anyone has ever actually successfully done it.
Sounds like one of those things where the money is in the courses.
