For those of you who haven't followed every post in this thread, I bet 1 unit to win almost 97 units shortly after Doug posted his bet. If Keys wins I'm going to hedge my bet.
Sinner is currently at -273. I'm going to bet 55 units to win 20 units on Sinner. If he wins I am guaranteed at least 20 units. If Zev wins, I win 97-50 = 47 units.
