Card Counting Formula:
From: | To: |
Card counting is a strategy used in blackjack to determine whether the next hand is likely to give a probable advantage to the player or the dealer. It involves tracking the ratio of high cards to low cards remaining in the deck.
The calculator uses two key formulas:
Where:
Explanation: The true count gives a more accurate picture of the deck's composition by accounting for how many cards remain to be played.
Details: The true count is crucial because it determines when to increase your bets (when the count is positive) and by how much. A higher true count indicates more high cards remaining, which favors the player.
Tips: Enter your current running count (using whatever counting system you prefer), estimate how many decks remain in the shoe, and set your base betting unit. The calculator will show the true count and recommended bet size.
Q1: What counting system should I use?
A: The Hi-Lo system is most common (+1 for 2-6, -1 for 10-A, 0 for 7-9), but this calculator works with any balanced counting system.
Q2: How accurate are deck estimations?
A: Accuracy improves with practice. Many players estimate to the nearest half-deck after some experience.
Q3: Should I always bet the calculated amount?
A: Adjust based on your bankroll and casino conditions. This is a theoretical optimal bet.
Q4: What does a negative true count mean?
A: It means the remaining deck is rich in low cards, favoring the dealer. You should bet the minimum or not play.
Q5: Is card counting illegal?
A: No, but casinos may ask you to leave if they suspect you're counting cards.
