Blackjack is one of the most popular card games in traditional and online casinos. With simple but strategic rules, Blackjack attracts both new and experienced players. However, many new players often make basic mistakes, significantly reducing their chances of winning. The article below by In 999 will help you identify common mistakes and guide you on how to overcome them to effectively improve your skills.
1. Not Learning Basic Strategy
Mistake:
Many new players enter the game without any knowledge of basic strategy – the tool that helps them make optimal decisions based on their cards and the dealer’s upcard.
How to avoid it:
Learn and apply the standard Basic Strategy. This strategy chart has been analyzed based on mathematical probability and is the foundation of smart play. You can print out the chart or practice using a Blackjack simulator.

2. Relying solely on gut feeling
Mistake:
Many people believe that intuition or “good feelings” will help them win big. However, Blackjack is a game of specific calculations, and gut feelings often lead to inaccurate decisions.
How to avoid it:
Rely on data and strategy, not emotions. Always double-check that your actions are consistent with the basic strategy chart.
3. Splitting at the wrong time
Mistake:
New players often split all pairs of the same hand because they think they have a chance to win twice. In fact, splitting is not always the right move.
How to avoid:
Only split pairs that are advantageous, such as 8-8 or A-A. Never split 10-10 or 5-5. Learn the standard decision table to apply it correctly in the right situation.

4. Doubling at the wrong time
Mistake:
Some new players double their bets on impulse, even when their hand is not favorable, leading to a quick loss of money.
How to avoid:
Doubling only when you have a strong hand and the dealer is weak. For example, when you have 10 or 11 and the dealer has a 2 to 6 up. Doubling should be done strategically.
5. Not Managing Your Bankroll
Mistakes:
Many new players do not set a betting limit and easily get caught up in a losing streak without controlling their emotions, leading to heavy losses.
How to avoid:
Set a playing budget before you start, and strictly follow it. When you lose to the set limit, stop instead of trying to recover.

6. Not understanding the specific rules of the Blackjack table
Mistakes:
Each Blackjack table may have different rules (for example, whether the dealer hits on soft 17 or stands; whether doubling after splitting is allowed, etc.). Newbies often ignore this.
How to avoid:
Before playing, carefully read the specific rules of the Blackjack table you are participating in. The rules can affect how to apply the strategy.
7. Betting like other players
Mistakes:
Some new players have the habit of observing and imitating others, thinking that it is a good way to learn. However, not everyone plays the right strategy.
How to avoid:
Be confident in your strategy. Don’t copy other players’ actions if you’re not sure they’re playing the right strategy.
8. Ignoring the house edge
Mistake:
Newbies often don’t realize that the house edge is real and will always exist if you don’t play the right strategy.
How to avoid:
Understand that Blackjack is a game that can reduce the house edge to less than 1% if you play it right. On the other hand, small mistakes can increase this advantage significantly.
9. Playing too fast, not observing
Mistake:
Newbies often play too fast, not giving themselves enough time to think before making a decision.
How to avoid:
Play slowly, with control. If you play online, you can use the trial mode to practice your reflexes and observe more carefully before acting.
Blackjack is a game that requires players to combine luck and strategy. Common mistakes such as not learning strategy, betting emotionally, not managing capital… can all cause new players to lose the opportunity to win big. However, just understanding and avoiding basic mistakes can create a solid foundation to become a skilled Blackjack player.
Invest time in learning strategy, practicing regularly and honing observation skills. Success in Blackjack does not come from luck, but from knowledge and consistency in playing.
