In blackjack, using a card counting strategy like the Big Jack Ace, the number of decks being used can impact the effectiveness of the strategy chart. The more decks there are, the more mixed up the undealt cards become, making it harder to gain an accurate advantage. In my experience, I've found BJA works best with 1-2 decks, while with 6 or 8 decks the chart must be used more loosely and gains are more minimal. For high level players the number of decks is an important consideration.
