I know from experience with chess programs that if the score is getting down
there is more chances that it will continue to get down and not to go up.

I did not do statistics about it but I believe that I am right.

I think that if the human who help the computer is not a bad player and have
experience with computers and also takes the challange seriously then the team
of human and computer will probably win.
