How did a blackjack player manage to win $15 million from Atlantic City casinos over the course of several months?

“As Johnson remembers it, the $800,000 hand started with him betting $100,000 and being dealt two eights. If a player is dealt two of a kind, he can choose to ‘split’ the hand, which means he can play each of the cards as a separate hand and ask for two more cards, in effect doubling his bet. That’s what Johnson did. His next two cards, surprisingly, were also both eights, so he split each again. Getting four cards of the same number in a row doesn’t happen often, but it does happen. Johnson says he was once dealt six consecutive aces at the Mohegan Sun casino in Connecticut. He was now playing four hands, each consisting of a single eight-card, with $400,000 in the balance.

“He was neither nervous nor excited. Johnson plays a long game, so the ups and downs of individual hands, even big swings like this one, don’t matter that much to him. He is a veteran player. Little interferes with his concentration. He doesn’t get rattled. With him, it’s all about the math, and he knows it cold.”
