Thorp is the father of card counting, and in this classic guide he shares the revolutionary point system that has been successfully used by professional and amateur card players for generations. This book provides: o an overview of the basic rules of the game o proven winning strategies ranging from simple to advanced. The man behind the name, 'Fortune's Formula,' is a living legend: Edward O. In 1958 Thorp was a young, up and coming professor at MIT. He went to Las Vegas on a holiday vacation and experimented with a blackjack strategy about which he recently read.

Edward Oakley Thorp (born August 14, 1932) is an American mathematics professor, author, hedge fund manager, and blackjack researcher. He pioneered the modern applications of probability theory, including the harnessing of very small correlations for reliable financial gain.

Contents

Thorp is the author of Beat the Dealer, which mathematically proved that the house advantage in blackjack could be overcome by card counting.[1] He also developed and applied effective hedge fund techniques in the financial markets, and collaborated with Claude Shannon in creating the first wearable computer.[2]

Thorp

Thorp received his Ph.D. in mathematics from the University of California, Los Angeles in 1958, and worked at the Massachusetts Institute of Technology (MIT) from 1959 to 1961. He was a professor of mathematics from 1961 to 1965 at New Mexico State University, and then joined the University of California, Irvine where he was a professor of mathematics from 1965 to 1977 and a professor of mathematics and finance from 1977 to 1982.[3]

Introduction

Edward Thorp Blackjack

Basic strategy blackjack players sometimes ask me for a simple way to overcome the small house edge in blackjack, with little worry over being recognized as a card counter. This is often done with the motive of milking the casinos for comps and offers. What follows is, in my opinion, the easiest card counting strategy to achieve the above goal and still put the odds in the player's favor.

How It Works

  1. Establish what your minimum and maximum bets will be. Usually the maximum will be 8, 16, or 32 times the minimum bet, or any power of 2, but you can use whatever bet spread you wish.
  2. At the beginning of each shoe, start with your minimum bet, and a count of zero.
  3. For each five observed, add one to the count.
  4. For each ace observed, subtract one from the count.
  5. If the count is greater than or equal to two, then double your last bet, up to your maximum bet.
  6. If the count is less than or equal to one, then make the minimum bet.
  7. Use basic strategy for all playing decisions.

This strategy was designed to be most effective on a six- or eight-deck game. I recommend playing only on games with liberal Strip rules, which are as follows:

  • 4-8 decks
  • Blackjack pays 3 to 2
  • Dealer stands on soft 17
  • Double after split allowed
  • Late surrender allowed
  • Re-splitting aces allowed
  • 75%+ penetration

Such games are easy to find in Las Vegas, although sometimes a higher minimum bet is required. In the low-roller pits, the dealer will usually hit on a soft 17, which is bad, costing the player 0.22%.

Simulation Results

The following results were provided by Norm Wattenberger using his Casino Vérité software. The rules above were used, with six decks, and 75% penetration. In my opinion, Casino Vérité is the most robust and accurate blackjack simulation software on the market. It can be used to test just about any card counting strategy under any set of rules and conditions.

SCORE is an acronym, coined by Don Schlesinger, for Standardized Comparison Of Risk and Expectation. It is defined as the advantage squared divided by the variance. The SCORE may also be interpreted as the expected hourly win per hand for a player with a $10,000 bankroll, who sizes his bets according to the Kelly Criterion, to achieve a 13.5% risk of ruin. As a basis of comparison, a Hi-Lo counter, with a 1 to 8 spread, under the same rules, has a SCORE of 8.40, compared to the 3.1 of the Ace/Five count.

Earlier Strategies

After publishing this section, somebody accused me of stealing the idea from Edward Thorp. Indeed, in 1969 Thorp did discuss a similar strategy in his book 'Beat the Dealer,' in the fourth chapter titled 'A Winning Strategy.' The difference is that Thorp's strategy tracks fives remaining against total cards remaining. Later, in 1971, Lawrence Revere published a similar strategy as Thorp's in 'Playing Blackjack as a Business,' chapter 7 titled 'The Revere Five Count Strategy.'
