After moving to Las Vegas, Richard Marcus became homeless but later found a job as a baccarat and blackjack dealer. As he learned the intricate details of the games, he discovered approaches to defraud the system. One of his best tricks was "past posting," or late wagering, in which he'd bet low amounts, hold back to check whether he'd won, and then secretly switched the low-denomination chips with higher-value ones to win big. He managed to swindle more than $5 million. He was finally caught by law enforcement but was never imprisoned.
