How to Read Strategy Charts
Reading Blackjack Strategy Charts Right
Core Math
Basic strategy charts are key for best blackjack play, giving players tested decisions for all card mixes.
These charts help bring the house edge to about 0.5%, making them must-haves for serious players.
Using the Charts
Charts show a simple grid:
- Player cards on the left
- Dealer’s card at the top
- What to do at each cross point:
- H for Hit
- S for Stand
- D for Double Down
- P for Split
Making the Right Call
Choices in the chart come from millions of math tests, not guesses or hopes but there’s more
Each choice is the best play, losing less and winning more over time. Like, hit on 16 against a dealer’s 7, as the math shows it works out better in the long run than standing.
Rules Matter
Different rules change strategy:
- Dealer hits or stands on soft 17
- Double down limits
- Split rules
- Insurance options
Pick charts that match the casino rules you play with to stay on top.
Paying attention gets you the most right moves possible in any game setting.
Using the Charts Well
To make these charts work:
- Find your hand total
- Check the dealer’s card
- See where they meet
- Do what the chart says
This step-by-step way turns detailed odd calculations into clear, do-this-now choices for each hand.

Math Behind It
Calculating blackjack house edge, the key rate showing the casino’s edge.
The house edge rate is what players tend to lose each bet over time with the right strategy.
What Changes the Edge
Several keys shift the casino edge:
- Specific game rules (dealer hits/stands on soft 17)
- How many decks
- How much you get for winning hands
- What players tend to choose
- 공식 인증업체 목록
- Card combo stats
Usual Edge Range
The usual house edge with six decks in blackjack is 0.5% to 1.5%.
Advanced programs checking millions of hands confirm these through deep odd checks.
Knowing this lets players spot good game setups and know what they might get back in any game type.
Chance of Bust
Blackjack Bust Odds Made Clear
Main Bust Odds for Player Hands
Bust odds are core to the best blackjack plans. Risk goes up with bigger hand totals:
- Hard 12: 31% bust chance
- Hard 13: 39% bust chance
- Hard 14: 47% bust chance
- Hard 15: 54% bust chance
- Hard 16: 62% bust chance
- Hard 17+: 0% bust next card
Play Choices by Dealer Card
Dealer bust odds set what play you should make. With dealer 6 or less, about 42% bust chance, lay low with hard 12 to 16.
This math fact drives the basic plan to stand with those cards against dealer 4, 5, or 6.
But, with a dealer card of 7 or more, lower dealer bust chance means you need to take more risk.
The smart move is hitting on 16 or less, even though it raises your bust chance. Each new hit shifts the odd mix, upping bust chance as low cards come out.
Card Counting Math
How Card Counting Works in Numbers
Effect of Card Removal
Card counting systems work on exact math rules about card removal effects. The systems tag number values to card types, letting players track big deck changes.
The basic Hi-Lo counting system gives minus one (-1) to high cards (10s, Jacks, Queens, Kings, Aces) and plus one (+1) to low cards (2 to 6), while middle cards (7 to 9) have zero value.
Running Count vs. True Count Math
The running count turns more precise as true count by dividing by decks left. This key math step weighs how thick the deck is – a +6 running count means different things with different deck counts left.
The numbers show that a high count means more high cards left, upping the shot for natural blackjacks and strong hands.
Math Edge and Smart Plays
With a true count of +2 or more, math shows about 0.5% better chance per unit up. This clear edge sets up best bet sizes and smart moves off the usual plan.
The exact math of card counting lets players make moves based on their knowledge of the deck.
