The Revere Plus-Minus Blackjack Card Counting System

This Blackjack card counting system was developed by Lawrence Revere in 1980. The Revere Plus-Minus Count is an easy to understand and implement card counting system for single deck Blackjack. It has been proven to be very effective over the past three decades. The only setback to using the Revere Plus-Minus Count is that it only works at single deck Blackjack tables. Casinos use multiple deck shoes at their Blackjack tables to make it more difficult to count cards so you may not find too many opportunities to use this card counting formula. Lawrence earned a mathematics degree at the University of Nebraska. He has pioneered several other Blackjack card counting systems including the 10-Count and the Revere Point Count. The Revere Plus-Minus Count system may seem somewhat primitive when compared to some of the more modern count systems but it is both reliable and easy to use, ideal traits for a card counting system.

Lawrence Revere is well known for playing both sides of the fence. His books trained early card counters but he also shared his knowledge with casino security teams and taught them how to spot card counters. Some of the counter-measures used to combat card counting systems like the Revere Plus-Minus Count were created using Lawrence’s inside information. Single deck Blackjack may be rare, but this system is a great starting off point for players who are not mathematically inclined.

How To Use The Revere Plus-Minus Count Blackjack System

The Revere Plus-Minus Blackjack formula only uses a running count since it was designed for single deck tables. Each card rank is assigned a -1 or +1 so if you know how to count you can use this system. Revere did not include Aces in this card counting scheme, but you can gain an additional edge by doing so on the side. I will explain how in more detail later in this article. In the Revere Plus-Minus Count cards ranging from 2 to 6 should be counted as +1. Nines and ten point cards will be counted as -1. All other cards will not be counted, as is shown in the image below.

This card counting system will tell you when it is fortuitous to bet more or when the house has an increased edge. When you’re running Revere Plus-Minus Count is greater than 0 it means that the unused cards have a higher ratio of 9’s and 10 point cards then a new deck has. Adjusting the size of your bet according to your running count has been proven to be beneficial to the player. The edge will be slight in most cases, but Blackjack games have a house edge ranging from .28% to .5%. Changing the amount that you wager to correlate with the probable advantage determined by using the Revere Plus-Minus Count can put the advantage in your favor. You can essentially switch places with the house. Card counting systems like the Revere Plus-Minus Count should not be used with the expectation of winning huge amounts of money quickly. These systems favor players that tend to play long sessions on a regular basis.

The Ace is the most important card in Blackjack. If an increased high card to low card ratio benefits the player the same is true for Aces, despite there being only four of them in a single deck. Since the Revere Plus-Minus Count is so simple you should not have any difficulty keeping an eye on the Aces. If half of the deck has been used but only one Ace has been played you will have a slight edge.
