Changes:
- Added the new UCI option FightingSpirit (0 ... 100).
This allows the user to make the engine play in a more fighting, ambitious, and aggressive style without simply making it weaker.
...
Hello,
thanks for sharing :D

Please, how does this FightingSpirit setting compares to v1.0? I see the default value is zero; does it mean leaving the default value would result in the same style as v1.0 played with, and any higher value would increase the aggressivity?
Or is 50 median value the one providing a balanced style similar to v1.0, and moving the cursor around would accordingly decrease or increase the aggressivity?

Regards,
Eric

If you would like to use another opening book, you could use the komodo opening book by Salvo Spitaleri: https://komodochess.com/pub/komodo_book.zip
If you want to develop your own book, you can use PGN Book Editor.
