Since so many people think Rebel vs. Rebel is meaningless for this experiment,
you should set it up so that Rebel counts the % of correct pondering during
these games.  Many people think it'll be much higher % than it would be against
other programs, so this would be a way to prove this right or wrong.  I think
Bob said he was going to run a similar experiment, and Crafty already counts the
number of correct ponderings.

Thanks for running this experiment, Ed. :)  It's a good piece of data on the
value of PB, which seems to be quite underestimated.
