Before the duplication SP bet that "I will see W". After the duplication SP1 sees W and SP2 sees M. SP1 says "I was right, I see W" and gets a reward. SP2 says "I was wrong, I see M" and does not get a reward. Everyone agrees that this is fair, no-one disputes who should get the reward. -- Stathis Papaioannou -- You received this message because you are subscribed to the Google Groups "Everything List" group.
