The true count in card counting is a more precise measure of the deck’s composition, especially in multi-deck games. It adjusts the running count by accounting for the number of decks remaining in play. To calculate it, you first track the running count as cards are dealt, then estimate how many decks are left in the shoe. By dividing the running count by the number of remaining decks, you get the true count. This adjusted figure gives a clearer picture of whether the deck is favorable to the player or dealer. A higher true count indicates a deck rich in high cards, which benefits the player, while a negative or low true count suggests a deck that favors the dealer.
