Passed pawns and other pawn issues in the Fruit Family are being worked on (By
at least 2 people likely 3).  I still plan on going with the PPP idea and
expanding from there in Gambit Fruit.  The idea still has a lot of holes in it
so I think it will take some time to get passed pawns done just right.  Also the
solution can not take too long to calculate or it will be counter productive.
