Was this one of Michael Gurevich testpositions? I can't remember this one in CSS
but haven't looked it up.
I haven't yet found a good Gambit Fruit setting for this. Almost default
settings with only more Chess Knowledge, less lazy eval, needs about an hour and
a half. Not sure if trying to improve this with just the settings would not just
hurt playing strength..
