Hi Steve,

i fully agree to Achim's advise. At some machines the KSO ROM cover is hard to remove - so does mine.

As Achim said, the advantage of KSO isn't much in the mean of ELO. The machine "knows" much more openings, if KSO is present and therefore it might earn a slight advantage of time, as it can play some more moves out of the bigger book. On the other hand some people mentioned, the KSO opening lines seem not designed for the playing style of Turbo Star - means, the KSO lines often lead to positions the machine don't understand. I don't have that much experiences with this computer and can neither agree, nor disagree. But if it is true that the KSO often lead to such positions, it might even drop down the machines playing strength. I can imagine, it also depends on its opponent (human or computer) whether the KSO will lead to an advantage or disadvantage.

Regards, Wilfried
