Card counting is a blackjack strategy used to determine whether the player or the dealer has an advantage on the next hand. Card counters are advantage players who try to overcome the casino house edge by keeping a running count of high and low valued cards dealt. They generally bet more when they have an advantage and less when the dealer has an advantage. They also change playing decisions based on the composition of the deck. (資料來源 )
2. Hi-Opt I 和 Hi-Opt II:這些方法在高低法的基礎上進一步發展,對不同牌值賦予不同的權重。例如,Hi-Opt I將2和3計為+1,而4則計為+2。這些複雜的方法可以提供更準確的預測,但需要更高的記憶和計算能力。
The Hi-Lo system is a level-1 count; the running count never increases or decreases by more than one. A multilevel count, such as Zen Count, Wong Halves, or Hi-Opt II, further distinguishes card values to increase accuracy. An advanced count includes values such as +2 and −2, or +0.5 and -0.5. Advanced players might also keep a side count of specific cards like aces. This is done where betting accuracy differs from playing accuracy.
Many side count techniques exist, including special-purpose counts used for games with nonstandard profitable-play options such as an over/under side bet. (資料來源 )
