Card counting at a blackjack table with multiple players requires staying focused on the deck while managing distractions. The most effective method is to use a simple counting system like Hi-Lo, where you track high and low cards dealt. As cards are played, you keep a running count and adjust your bets based on whether the deck is rich in high cards (which favors the player). In a multi-deck game, you convert your running count to a true count by factoring in the number of decks left, which improves accuracy. It’s crucial to adjust your betting size subtly to avoid drawing attention, especially since other players' actions won’t directly affect your strategy. By focusing on the cards rather than the players, you can gain an edge, but maintaining concentration and discretion is key.
