It must be something with the Fritz GUI. I can now make it behave, and know what
to do to give strange results, but it's still odd. If I open the Fritz GUI, and
then load the Pro Deo engine, even though the engine is already chosen, it will
behave and give the same results as CP. However, if I open the Fritz GUI, and
Pro Deo was already the chosen engine, and have it start in infinite analysis, I
get different results. I tested this twice on my end to see whether I wasn't
going crazy. Weird....
One last question (well... next to last): is there any point in using both King
Safety values? One is the new style, and the other is the old. I presumed that
one is supposed to replace the first, but Thorsten suggested both are useful.
Same question applies for the other values with old and new styles.
