Shouldn't each team have a separate book for important competetions and one for commercial use? That way people can prepare until they are blue in the face but they won't know in advance what you will play. This is a testament to the strength of todays programs. When programs were much weaker I think it mattered less since there were so many opportunities to take advantage of weak moves. Now you can lose a game in the opening book before the computer has a chance to play the first move on its own! When cilkchess gets into trouble out of the opening book it generally takes a long time to recover (assuming we recover at all.)
