Lessons from Colin Jones

Colin Jones played professional blackjack for years before managing the Church Team, a heavily capitalized card-counting group that won millions from casinos. He wrote The 21st-Century Card Counter to explain how to hold a mathematical edge against modern surveillance without going broke from statistical variance. This profile collects his rules for calculating expected value and managing the financial risk of a betting operation.

Part 1: The Mathematics of Expected Value

  1. On the nature of advantage play: "You are not gambling; you are simply executing a mathematically proven edge over a large enough sample size." — Source: [Blackjack Apprenticeship]
  2. On expected value: "Every decision at the table has an exact mathematical value. Your job is to constantly make the positive expected value choice regardless of short-term results." — Source: [The 21st-Century Card Counter]
  3. On the gambler's fallacy: "Cards do not have a memory. A table is not due for a win just because it has been losing for hours." — Source: [Blackjack Apprenticeship YouTube]
  4. On true count conversion: "The running count only tells you the total excess of high cards. Dividing by the decks remaining gives you the true count, which dictates your actual edge." — Source: [The 21st-Century Card Counter]
  5. On bet sizing: "Your bet must scale proportionally with your edge. Betting small when the count is high negates the entire purpose of advantage play." — Source: [American Casino Guide Interview]
  6. On side bets: "Most side bets carry an enormous house edge. Unless a specific side bet can be quantified and beaten, it is just a casino tax on impatient players." — Source: [Gambling With An Edge]
  7. On the flow of the cards: "There is no such thing as the flow of the cards. Anyone telling you to play by feel is offering advice that will mathematically ruin you." — Source: [Blackjack Apprenticeship YouTube]
  8. On basic strategy: "It is not a suggestion; it is the mathematical foundation of everything we do. Without perfect basic strategy, counting cards is worthless." — Source: [The 21st-Century Card Counter]
  9. On long-term guarantees: "The math only protects you in the long run. In the short term, you are entirely at the mercy of statistical noise." — Source: [Unabated Podcast]

Part 2: Managing Risk and the Bankroll

  1. On the importance of a bankroll: "Your bankroll is your inventory. If you lose your bankroll, you are out of business no matter how good your counting skills are." — Source: [The 21st-Century Card Counter]
  2. On risk of ruin: "You must calculate your risk of ruin before you ever place a bet. If your risk is above two percent, you are playing too aggressively." — Source: [Blackjack Apprenticeship]
  3. On the Kelly Criterion: "Betting proportional to your bankroll and edge maximizes growth, but betting full Kelly can lead to extreme volatility. Fractional Kelly is often necessary for sanity." — Source: [Gambling With An Edge]
  4. On overbetting: "The most common way advantage players fail is by betting larger than their bankroll can sustain. Overbetting turns a winning game into a losing one." — Source: [American Casino Guide Interview]
  5. On trip bankrolls: "Never bring your entire bankroll on a single trip. Separate your money into trip bankrolls to ensure a catastrophic run of bad variance does not wipe you out." — Source: [The 21st-Century Card Counter]
  6. On emotional betting: "Chasing losses by increasing your bet size outside of what the count dictates is the fastest way to empty your pockets." — Source: [Blackjack Apprenticeship YouTube]
  7. On replenishing funds: "If you view your bankroll as money you might need for rent, you will play scared. A bankroll must be completely separate from living expenses." — Source: [The FI Show Interview]
  8. On expected hourly rate: "Your EV is a mathematical projection rather than a paycheck. You might generate hundreds of dollars of EV an hour and walk out down thousands." — Source: [Blackjack Apprenticeship]
  9. On variance reserves: "You need a much larger bankroll than most people think to weather the natural swings of a one percent edge." — Source: [Gambling With An Edge]
  10. On sizing down: "When your bankroll drops from a losing streak, your unit size must drop with it. Ego cannot dictate your bet spread." — Source: [The 21st-Century Card Counter]

Part 3: The Reality of Variance and Losing Streaks

  1. On losing streaks: "Every card counter will experience a losing streak that feels mathematically impossible. It is not impossible; it is just variance." — Source: [The 21st-Century Card Counter]
  2. On hours played: "You cannot judge your success or failure over a weekend. True advantage play is measured in hundreds of hours of table time." — Source: [Blackjack Apprenticeship YouTube]
  3. On trusting the math: "When you are down hundreds of units, the only thing that keeps you going is absolute trust in the math and your own exact execution." — Source: [American Casino Guide Interview]
  4. On winning streaks: "Winning streaks are just as dangerous as losing streaks because they trick you into thinking you are invincible. You are still just playing a slight edge." — Source: [Gambling With An Edge]
  5. On standard deviation: "Understanding standard deviation is what separates professional players from amateurs who quit after a bad month." — Source: [The 21st-Century Card Counter]
  6. On N-zero: "N-zero is the number of hands it takes for your expected win to exceed one standard deviation. It is the best metric to understand how much you need to play to outrun luck." — Source: [The 21st-Century Card Counter]
  7. On emotional detachment: "You have to reach a point where winning or losing identical amounts feels exactly the same because you know you played the hands correctly." — Source: [Blackjack Apprenticeship]
  8. On the grind: "The reality of card counting is that it is often a tedious and grueling grind. The glamour portrayed in movies does not survive a long downswing." — Source: [Cigar Aficionado]
  9. On doubt: "When you lose for a month straight, you will doubt your counting, your bet spread, and your sanity. That is when you need to run your game through a simulator again to confirm you are playing a winning game." — Source: [Gambling With An Edge]

Part 4: Training and Execution

  1. On practice: "You should not step foot in a casino until you can keep the count perfectly through a shoe with distractions, noise, and conversation." — Source: [Blackjack Apprenticeship YouTube]
  2. On testing: "We required every player on our team to pass a rigorous test out before they were allowed to bet a single dollar of team money." — Source: [The 21st-Century Card Counter]
  3. On playing deviations: "Memorizing the Illustrious 18 deviations provides the vast majority of the value. You do not need to learn hundreds of index numbers to beat the game." — Source: [Blackjack Apprenticeship]
  4. On fatigue: "A tired card counter is a losing card counter. When your brain gets foggy, your error rate spikes and your edge disappears." — Source: [American Casino Guide Interview]
  5. On the cost of mistakes: "A single deviation from basic strategy or a missed true count conversion can wipe out hours of expected value. Precision is mandatory." — Source: [The 21st-Century Card Counter]
  6. On counting speed: "Speed is important, but accuracy is everything. It is better to play slower and perfectly than fast and sloppy." — Source: [Blackjack Apprenticeship YouTube]
  7. On software training: "Use training software to simulate hundreds of thousands of hands. It is the only way to experience long-term variance before risking actual money." — Source: [Gambling With An Edge]
  8. On acting natural: "You have to be able to execute the math flawlessly while appearing entirely relaxed and natural to the pit boss watching you." — Source: [Cigar Aficionado]
  9. On self-evaluation: "Record your play, track your hours, and constantly evaluate your own execution. The casino will not correct your mistakes." — Source: [The 21st-Century Card Counter]
  10. On continuous learning: "The game conditions change constantly. You have to adapt your bet spreads and game selection to match the current environment." — Source: [Unabated Podcast]

Part 5: Building and Managing a Team

  1. On pooling bankrolls: "The primary advantage of a team is pooling money. A larger bankroll lowers the risk of ruin and allows everyone to bet at a much higher level." — Source: [The 21st-Century Card Counter]
  2. On shared variance: "When you have ten people playing simultaneously, you smooth out the variance. One player’s terrible month is offset by another player’s great month." — Source: [American Casino Guide Interview]
  3. On trust: "You can teach anyone to count cards, but you cannot teach them honesty. Trust is the single most important factor in a blackjack team." — Source: [Blackjack Apprenticeship YouTube]
  4. On spotting theft: "We tracked every metric. If a player’s expected value did not align with their actual results over a long enough period, we knew we had a problem." — Source: [Gambling With An Edge]
  5. On vetting members: "Our vetting process focused more on character and discipline than raw mathematical talent. A disciplined player is far more valuable than a reckless genius." — Source: [The 21st-Century Card Counter]
  6. On management structures: "Managing a blackjack team is running a business. You have investors, employees, expenses, and spreadsheets tracking every dollar." — Source: [The FI Show Interview]
  7. On the Church Team: "We recruited heavily from our church community because we knew these people had shared values and a baseline of accountability." — Source: [Blackjack Apprenticeship]
  8. On paying players: "Compensating players based on expected value rather than actual wins kept morale high and incentivized volume over short-term results." — Source: [The 21st-Century Card Counter]
  9. On ending a team: "Teams have a natural lifespan. Eventually, players get tired of the travel, get backed off from too many properties, or want to manage their own money." — Source: [Gambling With An Edge]

Part 6: Casino Countermeasures and Heat

  1. On back-offs: "Getting backed off is a normal part of the job. It means you are playing a winning game and the casino has noticed. Take it as a compliment." — Source: [The 21st-Century Card Counter]
  2. On cover plays: "Most cover plays cost you too much EV to be worth it. The best cover is simply playing short sessions and leaving before they figure you out." — Source: [Blackjack Apprenticeship YouTube]
  3. On surveillance: "The eye in the sky is looking for large bet spreads and players who move their money exactly with the count. Your job is to obscure that correlation as long as possible." — Source: [Cigar Aficionado]
  4. On interacting with pit bosses: "Be polite and be forgettable. The goal is to look like a tourist with too much money rather than a math wizard." — Source: [American Casino Guide Interview]
  5. On casino databasing: "Facial recognition and shared databases mean a back-off at one property can easily lead to a back-off at another across the country." — Source: [The 21st-Century Card Counter]
  6. On trespassing: "Know the laws of the jurisdiction you are playing in. There is a massive difference between a verbal back-off and being formally trespassed." — Source: [Gambling With An Edge]
  7. On game selection: "Playing a poorly dealt game just to avoid heat is a losing strategy. Always prioritize games with good penetration and rules before managing the heat." — Source: [Blackjack Apprenticeship]
  8. On longevity: "If you want to play in a specific market for years, you have to keep your sessions incredibly short and your bet spreads modest." — Source: [The 21st-Century Card Counter]
  9. On burning out properties: "Sometimes the math dictates that you should just extract as much value as possible from a casino until they kick you out, rather than trying to preserve longevity." — Source: [Blackjack Apprenticeship YouTube]

Part 7: The Mindset of an Advantage Player

  1. On detachment from money: "You have to view chips as tools instead of money. The moment you think about what a black chip could buy in the real world, you compromise your decision-making." — Source: [The 21st-Century Card Counter]
  2. On ego: "Casinos are built on the egos of gamblers. An advantage player must completely abandon ego and submit to the math." — Source: [Gambling With An Edge]
  3. On handling losses: "When you lose, review your play. If you played perfectly, you did your job. The result of the hand is irrelevant." — Source: [Blackjack Apprenticeship YouTube]
  4. On routine: "Professional blackjack is highly repetitive. You need a mindset that finds satisfaction in executing a routine flawlessly rather than seeking thrills." — Source: [American Casino Guide Interview]
  5. On casino environments: "The casino is designed to distract you with lights, noise, and alcohol. You have to exist in a bubble of concentration." — Source: [Cigar Aficionado]
  6. On isolation: "Advantage play can be lonely. Most people will not understand your career, and they will think you are just a degenerate gambler." — Source: [The 21st-Century Card Counter]
  7. On entitlement: "The math owes you nothing today. It only promises an outcome over infinity. Never feel entitled to a win on any given trip." — Source: [Blackjack Apprenticeship]
  8. On process over outcome: "Focus entirely on the process of generating expected value. The outcome of any specific session is completely outside your control." — Source: [Unabated Podcast]
  9. On dealing with failure: "Getting backed off or suffering a massive downswing will test your resolve. Your ability to get back on the tables determines if you are a professional." — Source: [Gambling With An Edge]
  10. On complacency: "The best players are always reviewing their game, refining their bet spreads, and looking for new angles. Complacency kills your edge." — Source: [The 21st-Century Card Counter]

Part 8: Translating Edge to Business

  1. On investing: "Card counting is essentially value investing on a micro scale. You identify situations with a positive expected return and allocate capital accordingly." — Source: [The FI Show Interview]
  2. On risk tolerance: "Advantage play teaches you to become comfortable with calculated risk. Most people avoid all risk, which guarantees mediocre returns in business and life." — Source: [Blackjack Apprenticeship YouTube]
  3. On decision frameworks: "Once you understand expected value, you start applying it everywhere, from choosing investments to deciding how to spend your time." — Source: [The 21st-Century Card Counter]
  4. On emotional regulation in business: "The discipline required to endure a long downswing translates directly to the resilience needed to run a startup." — Source: [Unabated Podcast]
  5. On outcome independence: "Learning to judge decisions by their logic rather than their immediate results is the most valuable business skill you can take from the tables." — Source: [Gambling With An Edge]
  6. On hiring: "Just like vetting a blackjack team, hiring in business should focus on integrity and process execution rather than just raw intelligence." — Source: [The 21st-Century Card Counter]
  7. On scaling operations: "Scaling a blackjack team requires systems, training, and capital. It is identical to scaling any traditional business operation." — Source: [American Casino Guide Interview]
  8. On finding an edge: "Casinos are not the only place with exploitable inefficiencies. Once you train your brain to look for edges, you find them in real estate, the stock market, and entrepreneurship." — Source: [The FI Show Interview]
  9. On the ultimate goal: "The end goal of advantage play was never just to beat casinos. It was to accumulate enough capital and mental fortitude to fund a life of freedom." — Source: [The 21st-Century Card Counter]
