#2(9+9+1)🨫e7: bulgarian neutral Grasshopper
bulgarian Grasshopper Grasshopper who can only play if the jumper can make a grasshopper move without a capture.
When several movements of the jumper are possible, the choice belongs to the side of the neutral Grasshopper
(does it play as white or black ?)
