Seems unfair for the humans. Wouldn't a more fair match be a series of individual 1-on-1 matches with Watson and Jennings / Rutter? The current configuration means the two humans will both share the questions that are naturally difficult for computers, but Watson will dominate all the questions naturally hard for humans. Alternatively, to make it fair, we would need a 2nd copy of Watson competing, and if the two Watson's buzz at the same time, randomly pick one to answer.
