What about the SS setting in the recent SSDF match between CM8K and Junior?  Did
the SS setting remain at the default (7) for this match?  What settings changes
(if any) were made for this encounter?  If it remained at SS=7, why wasn't it
extended for the longer time control since there appears to be a fairly dramatic
increase in performance at long time controls?  Were there any (other) changes
in settings for this match?
