He doesn't count cards. Then how did Don Johnson break a string of Atlantic City casinos at the blackjack tables? Sly negotiation and a grasp of the long game.

The first and most obvious suspicion was card counting. Card counters seek to gain a strong advantage by keeping a mental tally of every card dealt, and then adjusting the wager according to the value of the cards that remain in the deck. (The tactic requires both great memory and superior math skills.) Made famous in books and movies, card counting is considered cheating, at least by casinos. In most states (but not New Jersey), known practitioners are banned. The wagering of card counters assumes a clearly recognizable pattern over time, and Johnson was being watched very carefully. The verdict: card counting was not Don Johnson’s game. He had beaten the casinos fair and square.
