# USTON APC-Blackjack Card Counting System

The Uston APC (Advanced Point Count) card counting system was developed by Ken Uston, and first published in his book, Million Dollar Blackjack, in 1981.  He also has 2 other card counting systems named directly after him, the Uston APM and the Uston SS.

The Uston APC is heavily considered his greatest accomplishment and one of the most powerful and effective card counting systems around.

After the success of his APM (Advanced Plus/Minus) system, designed for beginners, he wanted to give the professional players something they could use and so, the APC was developed.

It is a level three system, being very complex and difficult to learn.  It is not for a beginner player.

## How it works

There are 7 card values: -3, -2, -1, 0, +1, +2 or +3.  Your count starts at 0 and continues until there is a shuffle, where you again start the count at 0.

It is also a balanced system, meaning if you were to count down a deck, you would start and end at zero.

The card value chart is:

As seen in the chart above, there are not cards that easily cancel each other out, so the player has to pay more attention to the cards being dealt, in order to keep an accurate running count.

This system makes use of a true count, which adds to the difficulty of learning it. While the true count is not horribly difficult to figure out, it’s just another aspect of the system that makes it difficult and more involved.

For this system, this true count is calculated by dividing the running count by an estimate of the remaining decks in play. To quickly make that estimate while you’re at a live game, can be tricky.  However, the use of a true count is what increases the efficacy of this system.

The other added difficulty is in tracking aces. While counting aces is not part of the system, because aces are valued at zero, you can increase the advantage of using this system by also keeping track of the aces on the side.

In order to keep track of aces, you would start by figuring out the total number of aces available (number of decks x 4).  With a 6-deck game, it would be 24 aces(6×4). When an ace is dealt, you would subtract 1 from that total to keep an accurate count of the remaining aces.

Knowing the ace count, will help you decide whether to bet even more, when the true count is high and you know there are also a majority of aces still out.  You can deduce there is a greater chance of blackjack in that situation and you would want to bet bigger.
