Well, to decide whose go it is…
let’s use a tried and trusted method:
‘Rock-Hopper Penguin, Paper Tiger, Sciissortail Rasbora’.
How is it done?
Well … both parties have to shake their clenched fist up and down three times, finally opening their hand in the shape of a Rockhopper Penguin, Paper Tiger, or Scissortail Rasbora.
And, as everyone knows, a Rockhopper Penguin beats a Scissortail Rasbora, but is beaten by a Paper Tiger; and a Paper Tiger is beaten by a Scissortail Rasbora.
Who ever wins … is the winner.
