Of course Stefan will not be able to improve the engine by 200 points; it is
unlike to happen and there is no need as we are leading the SSDF list and always
playing to win the WCCC title, I mean if we do not win we get 2nd place. Last
year however we have been handicapped by a bad bug...

No, without a strong opening book, no matter how strong is your engine there are
no chances to win the WCCC.
Maybe 0% is too conservative; better to say 0.000000001% chances

Well, the point is to win, so instead of 0.000000001% chances it is better to
use one book that should raise these up to 50%...don't you agree?
