I was just speculating that Fruit might have got another 100 Elo improvement.I
WANTED Fabien to improve this public fruit a lot.But unfortnuately,Massy Version
and the public version seems nearly the same.so,I don't expect Fruit to finish
top 2,not even 3.#3 is at its best!

and BTW,Bob admitted a while ago that he hadn't seen any of Fabien's code and
had not seen any fruit-crafty games.so he has had no idea of how Fruit plays.
