For example, in Blackjack, whether the dealer hits on soft 17, or in Roulette, European single-zero vs. American double-zero, can make a significant difference. Always choose versions more favorable to the player.

I. Preparation: Reduce the Learning Curve, Master Core Rules
- Use Free Play to Learn the Rules
- Test games in demo mode on online platforms before risking real money.
- This is especially useful for games with complex rules, such as Blackjack or Video Poker.
- Record Rule Variations
- Different casinos and platforms may have variations in dealing rules, payouts, or betting limits, and these directly affect the expected value (EV).
- For example, in Blackjack, whether the dealer hits on soft 17, or in Roulette, European single-zero vs. American double-zero, can make a significant difference. Always choose versions more favorable to the player.
II. In-Play: Replace Intuition with Probability-Based Betting
- Use Probability and Payout Calculators
- When allowed, evaluate the true return rate of a bet using odds calculators or probability charts.
- Example: In Baccarat, a Tie bet may look attractive due to its high payout, but the long-term EV is clearly negative—avoid it.
- Tiered Betting Strategy
- Early stage: Flat, small bets (≤ 2% of total bankroll) to gather data and observe patterns;
- Mid stage: Lock in on low house-edge bets and maintain steady wagering;
- Late stage (winning streak or accumulated profit): Slightly increase bet size to amplify gains, but never exceed twice the original bet unit.
III. Knowledge Building: Keep Expanding Your Strategy Arsenal
- Read Professional Literature
- The Theory of Blackjack: Learn optimal strategy charts and card counting principles for Blackjack;
- The Mathematics of Gambling: Understand the probability models and bankroll management principles behind casino games.
- Analyze Empirical Research
- Study mathematical analyses and real-world casino data.
- Learn the actual performance and best use cases for betting systems such as 1-3-2-6 or D’Alembert.
IV. Defensive Play: Protect Your Bankroll Before Chasing Wins
- Set Win/Loss Limits
- Win limit: Consider cashing out after a 20%–30% profit;
- Loss limit: Stop playing if losses reach 10% of your bankroll to prevent emotional chasing.
- Split Your Bankroll
- Don’t put all your funds on a single game or table—keep reserves to handle volatility.
- Emotional Discipline
- Avoid reckless bet increases after winning streaks or doubling bets after losses;
- Keep detailed records to review and correct mistakes.
