Right.  And I believe that Bob asked to inspect it to see if there were
significant changes, and this request was denied by the Dutch tournament
officials.

I've proposed to the ICCA that for their tournaments, they insist that if
someone uses a free program as a base like this, that the new program be
available for inspection, as in "here is a disk, go look at it", before the
tournament.

My feeling is that if someone has "secrets" they don't want to reveal, either
the whole thing should be proprietary or none of it.

No word from the ICCA, no problem.

Very very good question.  Also, independent verification should be possible,
because everyone who does this will say that their changes were significant.

Maybe more, maybe not more, it's hard to tell from some tournament games.  You
could enter two identical programs in one of those tournaments, and one could
win while the other one finished way back.
