How to Use the Halves Counting System
The Halves Counting System is a card counting strategy developed by Ed Thorp, known for its simplicity and effectiveness in tracking the ratio of high to low cards remaining in the deck. It’s a balanced system, meaning it’s designed to provide accurate counts while being relatively easy to use. Here’s a step-by-step guide on how to use the Halves Counting System:
How to Use the Halves Counting System
Understanding the Card Values
In the Halves Counting System, each card is assigned a value of either +0.5, 0, or -0.5. Here’s a breakdown of the values:
- 2, 3: +0.5
- 4, 5, 6: +1
- 7, 8, 9: 0
- 10, J, Q, K, A: -1
Step-by-Step Guide
1. Start the Running Count
Begin your running count at zero at the start of the deck or shoe. As cards are dealt, adjust your running count based on the values assigned:
- For a 2 or 3: Add +0.5 to the running count.
- For a 4, 5, or 6: Add +1 to the running count.
- For a 7, 8, or 9: Do nothing (the count remains unchanged).
- For a 10, face card, or Ace: Subtract -1 from the running count.
Example: If the cards dealt are 2, 4, 10, and Ace, the running count would be +0.5 (2) +1 (4) -1 (10) -1 (Ace) = -0.5.
2. Convert to True Count
To adjust for the number of decks remaining in the shoe, convert the running count to the true count. This helps in making more accurate betting decisions:
- Estimate the Number of Decks Remaining: Calculate the approximate number of decks left in the shoe.
- Divide the Running Count by the Number of Decks Remaining: This gives you the true count.
Example: If your running count is -0.5 and there are 2 decks left, the true count would be -0.25 (-0.5 divided by 2).
3. Adjust Your Bets
The true count indicates how favorable the deck is. Adjust your bets based on the true count:
- Positive True Count: Increase your bets. A higher true count means a higher ratio of high cards remaining, which is advantageous for the player.
- Zero or Negative True Count: Place minimum bets. A lower or negative true count indicates a deck that favors the dealer.
Example: With a true count of +1, you might decide to increase your bet to 2 units instead of 1 unit.
4. Make Playing Decisions
The true count also helps in making strategic decisions such as hitting, standing, doubling down, or splitting. Generally, a higher true count favors aggressive play.
Example: With a high true count, you might choose to stand on a hand of 16 against a dealer’s 10, as there’s a higher chance the dealer will bust.

Conclusion
The Halves Counting System is a straightforward and effective card counting strategy that balances simplicity with accuracy. By maintaining a running count, converting it to a true count, and adjusting your bets and playing decisions based on this count, you can gain an edge over the casino. With regular practice and careful play, the Halves Counting System can be a valuable tool in your blackjack strategy arsenal.
