Blackjack Basic Strategy Chart

Never Split 10s

A hard 20 wins the vast majority of hands. Splitting it creates two hands starting at 10 — good, but nowhere near as strong as an already-complete 20. Splitting 10s is one of the most common and costly beginner errors.

House Edge in Live Blackjack on Playinexch

The house edge in blackjack depends on the specific rules at the table. Key factors: number of decks (more decks = slightly higher house edge), dealer hits or stands on soft 17 (dealer hit S17 increases house edge by 0.2%), and whether late surrender is available (lowers house edge by 0.07%). Standard 6-deck European blackjack with basic strategy has a house edge of approximately 0.5%.

Using the Chart During Live Play

On a live dealer table, you have a few seconds to decide each hand. Print or save the basic strategy chart and keep it available. In live online blackjack, using a strategy chart is completely acceptable — unlike in a physical casino where some establishments discourage it.

Commit the most common decisions to memory first: always split Aces and 8s, never split 10s, double hard 11 against everything but an Ace, stand on hard 17+. These cover the majority of hands you will encounter. See the Playinexch review for table rule details on specific blackjack variants.

FAQ

What is the house edge of blackjack with perfect basic strategy?

Approximately 0.5% with perfect basic strategy in standard 6-deck European blackjack. This is the lowest house edge of any standard casino game — lower than baccarat, roulette, and significantly lower than most slot machines.

Should I take insurance when the dealer shows an Ace?

No. Insurance pays 2:1 if the dealer has blackjack, but the probability of the dealer having a 10-value card in the hole is approximately 30.7% (in a 6-deck game). The insurance bet has a house edge of approximately 7.4%. Never take insurance unless you are counting cards — which does not apply in online live dealer games with frequent shuffles.

Can I count cards in Playinexch live blackjack?

Practically, no. Live dealer blackjack online typically uses continuous shuffling machines (CSMs) or shuffles after every hand, eliminating the running count advantage that card counting requires. Basic strategy is your best and only tool in this format.

Blackjack is the only casino card game where mathematically optimal play is publicly documented. A basic strategy chart tells you exactly what to do with every possible hand combination against every possible dealer upcard. Follow it precisely and the house edge drops from 3–4% (for guessing players) to approximately 0.5%. That gap is enormous.

This guide gives you the core blackjack basic strategy, explains the logic behind each key decision, and covers how to use it correctly on Playinexch live blackjack tables.

Why Basic Strategy Matters

Blackjack decisions — hit, stand, double, split, surrender — are mathematically solvable. For every combination of your hand total and the dealer’s visible card, there is an objectively correct play that maximises expected value over millions of hands. This is basic strategy.

Players who “play by feel” or use intuition make incorrect plays on roughly 15–25% of hands. Each wrong decision adds to the house edge. The cumulative effect of these errors on a 100-hand session is measurable. On Playinexch live casino, live blackjack tables run at standard European or multi-deck rules — and basic strategy for those rules is well-established.

The Core Basic Strategy Chart

The chart below covers the most critical decisions. Your hand is on the left; the dealer’s upcard is across the top. H=Hit, S=Stand, D=Double (hit if not allowed), Sp=Split, Su=Surrender (hit if not allowed).

Your Hand	vs 2–6 (dealer weak)	vs 7–9 (dealer neutral)	vs 10/A (dealer strong)
Hard 8 or less	H	H	H
Hard 9	D	H	H
Hard 10	D	D	H
Hard 11	D	D	D
Hard 12	S	H	H
Hard 13–16	S	H	H (Su if allowed)
Hard 17+	S	S	S
Soft 17 (A+6)	D	H	H
Soft 18 (A+7)	D	S	H
Soft 19+ (A+8+)	S	S	S
Pair of Aces	Sp	Sp	Sp
Pair of 8s	Sp	Sp	Sp (Su vs A)
Pair of 10s	S	S	S

Key Decisions and Why They Are Correct

Always Split Aces and 8s

A pair of Aces gives you a combined total of either 2 or 12 — both are weak starting points for a single hand. Splitting them creates two hands each starting with an Ace — the single most valuable card in blackjack. Always split, no exceptions.

A pair of 8s = 16, the worst total in blackjack. You lose more often standing (the dealer makes a non-bust hand) and more often hitting (you bust). Splitting turns two losing 16s into two hands starting from 8, both of which have better expected outcomes.
