* A Jim Brown: The fight between Frank Catton and Linus, staged to distract Terry Benedict so that Linus is able to pickpocket the security codes to the casino's vault. The con here is about a wealthy roller who has insider information. This is a reference to Ivan Boesky, a big-time trader on Wall Street who got caught committing securities fraud. Lyman Zerga is the whale who asks to put his jewels in the casino vault.
* A Boesky: This is the character of Saul playing Lyman Zerga.
