Urn a Red Ball?: Ellsberg's Ambiguity Effect

Urn a Red Ball?

You are the owner of a snooker club. Unfortunately, as a result of the actions of a colour blind thief, you're in a bit of a pickle. You're about to hold a snooker tournament, and you're short of red balls. Happily, the owner of rival snooker club, Balls "R" Us, has indicated he might be willing to lend you the requisite number of red balls. Unhappily, the owner is evil genius, Professor Zach Coine, and he's making you play a game for them.

Really Deep Thought

That seems to me a genuinely wicked thing to do - to disregard what somebody had quite explicitly said, that he wants to die - not to be resuscitated in certain circumstances and in certain circumstances to be helped to commit suicide.
