Amir Ban has already said that he would not show the Junior source code if the
ICGA asked him to.

Do you think that makes him or Shay "probably a cheater"? I don't.

If they asked Frans Morsche, or Stefan Meyer-Kahlen, or Amir Ban, Gian-Carlo
Pascutto, or any other commercial participant to show their source code, and
they refused because of the contracts they have with their employer (Chessbase,
Lokasoft, etc.), then would you say any of them are "probably a cheater"? I
wouldn't.

The problem is that there is an unwritten rule that the written rules aren't
really enforced. If they actually enforced the rules and made you prove that
your program is entirely your own work, I bet none of the commercial
participants would show up. They would probably start the Chessbase World
Championship or something.

The point is, there are plenty of good and acceptable reasons for not showing
your source code, and refusing to do so by itself is not enough to declare
someone "probably a cheater". If, on the other hand, there is solid evidence
that needs to be explained by the author, that is another situation.
