I understood, the match had been repeated on the same machines, each prog
getting 100% of the cpu. I consider the chance for producing another game from
the same start position as microscopically small.
But in principle, this possibilty is non-zero; so far I agree. But I would never
exepect to observe such drastic differences as posted here !
Of course, the thing is very different if you play from a book containing
weighted moves.
