DESCRIPTION:Playing games with imperfect information or randomness can be 
 tricky when playing remotely without a trusted third party. "Mental Poker"
  is the term used for the cryptographic problems that arise. We will first
  see a traditional example of how to use commitment protocols to emulate a
  fair coin toss\, and then move on to the trickier problem of card shuffli
 ng. While we will see that these problems are unsolvable in theory\, bound
 ing the computational power of the players can allow practical algorithms 
 to be developed.
