Ferz Army
25 Ferz (with king) Vs Chess army. Don't worry about the engine's initial evaluation. Setting custom piece values for the ferzes requires changing the variant's ID name, which causes runtime errors. So the base code is used, meaning the engine will miscalculate and underestimate the Ferz Army. Recommended to play against AI level 4 or higher for the best challenge.
