The concept of "true count" is essential in advanced card counting techniques in blackjack, as it provides a more accurate assessment of the game's conditions. While the running count indicates the ratio of high to low cards, the true count adjusts this figure based on the number of decks remaining in play by dividing the running count by the remaining decks. A higher true count signifies a greater proportion of high cards left in the deck, increasing the player's advantage. This adjustment enables players to make informed betting decisions, optimizing their strategies to take advantage of favorable situations while minimizing risk during unfavorable ones.
