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.

The house’s hand showed an upturned five. Arrayed on the table before him were the four eights. He was allowed to double down—to double his bet—on any hand, so when he was dealt a three on the first of his hands, he doubled his bet on that one, to $200,000. When his second hand was dealt a two, he doubled down on that, too. When he was dealt a three and a two on the next two hands, he says, he doubled down on those, for a total wager of $800,000.
