 Right, all comments are welcome - but some are more welcome than others...;)
 Thanks especially to yours. Very interesting. I noticed that almost all
 CM8 personalities that have shown good results also have a much higher
 King Safety value, 140-170 instead of default 100. Could this also be
 a good possibility for Nimzo 8? Though I see that you suggest a lower value
 for Nimzo (with at least 20%). How do you think a lower KS value would
 affect Nimzo's play? For sure I will try some of your suggestions, but
 I also noticed that the settings in Fritz are restored back to default,
 when closing and reopening the program?!
