Common Blackjack Mistakes and How to Avoid Them
Even experienced players make mistakes. Learn to identify and correct the most common errors that cost money at the table.
Why Mistakes Matter
A single incorrect decision can swing the odds significantly against you. Basic strategy reduces the house edge to 0.5%, but deviating from it increases the casino's advantage. Avoiding these common mistakes is crucial for long-term success.
Mistake #1: Hitting 12 vs 2-3
Wrong: Hitting 12 against dealer 2 or 3
Many players hit 12 thinking it's too low, but statistically you should stand.
Correct: Stand on 12 vs 2-3
The dealer is more likely to bust with 2-3 showing than you are to improve your 12.
Mistake #2: Not Doubling 11
Wrong: Hitting 11 instead of doubling
Players often hesitate to double, missing a huge mathematical advantage.
Correct: Always double 11
11 is the strongest starting hand. Double against any dealer card for maximum value.
Mistake #3: Splitting 10s
Wrong: Splitting a pair of 10s
It seems logical to split two good cards, but this is mathematically incorrect.
Correct: Never split 10s
20 is an excellent hand. Splitting turns one great hand into two mediocre ones.
Mistake #4: Taking Insurance
Wrong: Buying insurance when dealer shows Ace
Insurance seems like a safe bet, but it's a sucker bet that favors the casino.
Correct: Never take insurance
The odds are against you (about 6.7% house edge), making it a poor bet.
Mistake #5: Playing Too Many Hands
Wrong: Playing every hand for hours
Fatigue leads to poor decisions and increased losses.
Correct: Set time and loss limits
Play focused sessions and walk away when you're tired or losing.
