A strategic thinker and consummate gambler, Arnold "The Big Bankroll" Rothstein fixed the 1919 World Series and never makes a bet he doesn't know he'll win. He has been on both sides of a deal with Nucky, always keeping his options open, as well as nurturing the likes of young gangsters Charles "Lucky" Luciano and Meyer Lansky.
