What 9 kyus normally do  is something like this though (?):

White: that group is dead
Black: no it's not
White: try me
Black: <moves>
White: <moves>
Black: ok, it's dead

This is probably against the rules after passing twice, but happens in
clubs everywhere. There is no penalty for white here, since its black
who's trying to live and plays a stone first, white answers.

You don't show that a group is dead, your opponent has to show that it
can live, otherwise it's dead. No penalty for White, since he doesn't
have to show how to capture in the first
place unless black plays. I see no problem implementing that in a formal
protocol .
