This isn't a copyright issue, its not even a legal issue in the traditional
sense.  It is about the rules for a particular competition, namely the ICCA
World Computer Chess Championship.  If the rules say that you can't use someone
elses book in the tournament (and its not even clear that they do say this),
then you can't use someone elses book regardless of what copyright says.

Of course ICCA can't send you to jail if you break their rules :-)  But they can
chuck you out of their tournament.
