I'm afraid it will remain unclear forever (not that I'm too interested :o), if
the first version, or draft of that contract included an obligation to hand over
a complete package, including the opening book, or just the engine. IMO it would
*not* make sense for BGN nor Kramnik to have the opening book, for obvious
reasons (because they of course want to have a match, no killer book
preparation), so I think they would have removed that from the contract as soon
as it is explained (if necessary...) during negotiations. I think it's unusual
to make such details of contracts public.

If I want to take my chance and find parts of a contract I cannot agree with, I
try to negotiate them away - that's what Amir Ban tried to explain to us.

I do not assume, that BGN or any other organizer would let programs compete
under different contracts. Whoever suspects this, should first bring evidence
and talk later. So, do you think DF or DJ would agree to send their openings to
Kramnik 3 month before the final match, without the right to change anything?
This doesn't sound quite reasonable to me.

Providing the engine alone isn't such a problem I think, because in this case
Kramnik could not prepare for a small number of opening lines most likely to
reach. I do not think he would profit much more from a new engine version, than
from a current version, during his training.

Furthermore: I'm only guessing and may be wrong, but I don't think that he will
be able to use the match hardware for preparation. Therefore, he will only get a
rough impression more or less of what his opponent will be; he'll know much less
than he is used to know about the GM's he usually plays against. So lets not
overestimate this preparation issue.
