David Owen has a good overview piece on cheating in bridge at the New Yorker. (Read the article here.)
As I read it, I realized that one aspect it highlights is the crowd sourcing of the challenge: when somebody thought players were cheating at bridge, but could not see how, posting the videos on Youtube, and inviting the world at large to view and investigate brought about a solution. Also, it does seem that there may be a future opportunity to use a Big Data approach, if anyone puts the time and effort into converting all the on-table behavior into some kind of analytical data. Fascinating.
I still believe that there is a technology solution for professional bridge.
