Blackjack Basic Strategy: The Only Chart You Need

What basic strategy actually is

Blackjack is the one casino game where your decisions move the needle. Every other bet in the building has a fixed house edge baked in the moment you sit down. Blackjack hands you the wheel: play well and you barely lose, play on gut feeling and you bleed. Basic strategy is simply the mathematically best move for every hand you can hold against every card the dealer can show — worked out by running the exact rules of the game through a computer millions of times and keeping whatever loses the least.

It is not a system, it is not counting, and it is not a secret. It is a lookup table. For any total you are holding and any dealer up-card, there is one correct answer — hit, stand, double, or split — and basic strategy is the full set of those answers. Play it perfectly at the CoinLounge table and you hold the house edge to around half a percent. Ignore it and you can hand back five or ten times that without ever noticing. Same cards, same dealer, wildly different results, decided entirely by which button you press.

The whole thing is more learnable than it looks. There are really only three groups of hands to memorize, and each group has a handful of simple rules. Get those and you are playing the game as well as anyone at the table.

The table you're playing

Strategy only transfers if the rules match, so here is the good news: the chart below is built for exactly the game CoinLounge deals. No adjustments, no asterisks.

• Six decks, reshuffled deep into the shoe.
• Dealer stands on all 17s — soft or hard, the dealer never hits a 17. This is the player-friendly version (casinos call it "S17") and it is the single biggest reason the edge stays low.
• Blackjack pays 3:2 — a natural on 100 coins pays 150. This matters more than any strategy tweak; games that pay 6:5 quietly cost you well over a full percent.
• Double down on any first two cards — but not after a split.
• Split once (up to two hands), matching ranks only. Split aces get exactly one card each.
• No surrender, and the dealer peeks for blackjack before you act.

Because these are the actual rules — verified against the blackjack rules page — every move below is the genuinely optimal play here, not a rough approximation borrowed from some other casino's table.

The moves, grouped

Hard hands (no ace, or an ace that has to count as 1):

• Stand on hard 17 or more. Always. The bust risk on another card outweighs any upside.
• Hit hard 8 or less. You cannot bust and you need the cards — take one every time.
• Hard 9 — double when the dealer shows a 3 through 6; against anything else, just hit.
• Double hard 10 or 11 against a dealer showing a lower card (double 11 against everything but an ace; double 10 against everything but a 10 or ace). You are in the best spot on the table to catch one big card, so put more money out.
• The 12–16 zone is where hands are won and lost. Stand against a dealer 2 through 6 — those are the cards the dealer busts with, so let them. Against a dealer 7 through ace, hit and try to improve. (Fine point: hard 12 only stands against a 4, 5, or 6; hit it against a 2 or 3.)

Soft hands (an ace counting as 11, so you cannot bust on the next card):

• Stand on soft 19 or more (an ace with an 8 or higher). You are already ahead — leave it.
• Soft 18 is the trap. Stand against a dealer 2 through 8 — and when the dealer shows a 3 through 6, doubling is even better than standing — but hit against a 9, 10, or ace — that "18" is weaker than it feels against a strong up-card.
• Soft 17 or less: keep drawing, since you have a free swing at improvement. Turn it into a double when the dealer is weak (roughly a 4, 5, or 6), where you both improve your hand and punish a bust-prone dealer.

Pairs:

• Always split aces and 8s. Two aces become two hands each starting from a powerful 11; a pair of 8s is a miserable 16 you break into two fresh starts.
• Never split 10s or 5s. Twenty is already a winning hand — do not wreck it. And a pair of 5s is really a hard 10: double it if the dealer is weak, otherwise just hit.
• Split the middle pairs against weak dealers. Split 2s, 3s, 6s, and 7s when the dealer shows a low card; split 9s against 2–6 and 8–9, but stand on your 18 against a 7, 10, or ace.

That is the entire game. Print it in your head as three short lists — hard, soft, pairs — and you never have to guess at the table again.

The mistakes that cost the most

The biggest leaks are not obscure edge cases. They are common hands played on instinct: standing on 16 against a dealer 10 because a hit "feels" like a bust, hitting a soft 17 as if the ace could hurt you, or refusing to double 11 because betting more feels reckless. Each of those is just the wrong lookup-table answer, and they add up faster than anything else.

But the single most expensive habit is a side bet the game dangles at you.

Everything else is discipline. Basic strategy only works if you follow it on the hands that scare you, not just the easy ones. The 16-against-a-10 that makes you wince is precisely where the chart earns its keep.

Drill it free

Reading a chart and reflexively knowing that soft 18 hits against a 9 are two different things — and the gap between them is closed by repetition, not by studying. The fastest way there is to play a lot of hands where getting it wrong costs you nothing real.

That is the whole point of the CoinLounge table. Every coin is play money — no deposits, no cash-outs, nothing staked with real cash — so you can run through hundreds of hands, make the correct-but-uncomfortable move every time, and watch the pattern become automatic. Miss a double or blow a split? It's a learning rep, not a loss. Deal a few sessions and the three lists stop being something you recall and start being something you just do.

Sit down, play the chart, and skip the insurance. That is basic strategy — the closest thing to an even game the casino floor has, and it costs nothing to master here.
