Asakichi Cooke's ability:
Noon: Discard a card. Move one of your other dudes from this location (without booting, even if booted).
I'd always assumed that you have to move a dude if you use this ability, as it desn't say "You may move one of your other dudes...". However I've seen it played as allowing a discard without needing to move a dude, which leads me to the following questions:
Can the ability just be used to discard a card if there is a legal target at Asakichi's location that can be moved?
Can the ability just be used to discard a card if you have no other dudes at Asakichi's location?
