I think this is way over-rated here.  Because "rebel" after the first GM game
is not the same as "rebel" before the second GM game.  Rebel is a moving
target since it is being changed every week, just like crafty.  They can't
really prepare a lot based on prior games.  IE I would be perfectly happy
playing the _same_ GM one game per week for a year.  And would expect to do
just as well as if I played 52 games in one tournament vs 52 different GM
players.  It isn't easy to prepare vs a 'development' program.  If he was
playing a released version of rebel that couldn't be changed, that would be
a _big_ advantage.  But that isn't happening here...
