Card Counting Basics

Card counting works because high cards (10, J, Q, K, A) are worth -1, and low cards (2-6) are worth +1. Neutral cards (7-9) are worth 0. The running count is the sum of all cards seen so far.

Running Count Formula:

Running Count = (Number of High Cards) × (-1) + (Number of Low Cards) × (+1)

The true count adjusts the running count for the number of decks remaining. It's calculated by dividing the running count by the number of decks remaining.

Counting Methods

Different counting systems assign different values to cards. Here are the most common methods:

Hi-Lo System

2-6: +1
7-9: 0
10-A: -1

KO System

2-6: +1
7: 0
8: 0
9: 0
10: -1
J: -1
Q: -1
K: -1
A: -1

Omega II System

2: +1
3: +1
4: +2
5: +2
6: +1
7: 0
8: 0
9: -1
10: -2
J: -2
Q: -2
K: -2
A: 0

True Count Calculation

The true count is the running count divided by the number of decks remaining. This adjustment accounts for the fact that as more cards are dealt, the remaining deck becomes more balanced.

True Count Formula:

True Count = Running Count ÷ Number of Decks Remaining

For example, if you have a running count of +10 and 5 decks remaining, your true count would be +2.

Practical Application

Once you have your true count, you can use it to make better betting decisions. Here's a simple betting strategy:

True Count ≤ 0: Bet at the table's minimum
True Count = +1: Bet 1.5 times the minimum
True Count = +2: Bet 2 times the minimum
True Count = +3: Bet 3 times the minimum
True Count ≥ +4: Bet 4 times the minimum

Always remember that card counting is a skill that requires practice. The more you play and count, the better you'll become at estimating the true count.
