But, i think, it's not very strange to have queen on battlefield if think
that pieces are not single men, but battle detachment (all the more, it's
funny to imagine battle of only 32 people). Detachment can be commanded by
queen and by bishop (imagine fighting bishop is also funny). The more so
because in ancient India chess knight meant 3 (or 4, i don't remember)
horses, not one!
By the way, i read somewhere that in ancient Xiang-qi sets advisors where
represented as females...
