Why a chart feels harder than it is
A full basic strategy chart has well over a hundred cells, and staring at it as a grid of letters is a poor way to learn it. Most of those cells follow from a few ideas. If you learn the ideas first, the chart becomes something you can rebuild rather than something you have to recall.
This article is about learning method only. Basic strategy is the play that gives the lowest long-run cost in a given set of rules. It does not remove the house edge, it does not predict any single hand, and nobody can promise a result from using it. Treat it as a way to avoid needless extra losses while you play for entertainment.
Step one: split the dealer into weak and strong
Nearly every decision depends on the dealer’s upcard, and the upcards fall into two groups.
- Weak cards: 2 through 6. The dealer is relatively likely to end up with a stiff hand and bust. The reasons are covered in more detail in the piece on dealer bust cards.
- Strong cards: 7 through ace. The dealer is likely to finish with a made hand, so you cannot rely on a bust.
The six also acts as the “most generous” card in the middle of the weak group, which is why many players remember it as the dealer’s worst card. Once you hold this two-way split in your head, you have already learned the shape of most of the chart.
Step two: learn one rule per category
Each type of hand has a simple core idea. You can write all of them on a single index card.
Hard totals
For hard totals, think in four bands.
- 8 or less: hit. There is not enough to protect.
- 9, 10, 11: these are the doubling hands. You can only improve, and many cards help. Double more freely against weak cards, and less often as the dealer’s card strengthens.
- 12 to 16: the awkward zone. Stand against weak upcards, where the dealer may bust, and hit against strong ones, where waiting rarely helps. The one wrinkle is 12, which stands only against 4, 5 and 6.
- 17 or more: stand.
The reasoning behind each row is worked through in the article on hard totals.
Soft totals
A soft hand contains an ace counted as 11, so one more card cannot bust it. That is why you can do things with soft hands you would never do with a hard 13 or 14. The pattern is to treat soft hands as hands with a safety net.
- Ace with a small card (A2 to A6): hit, or double when the dealer shows a weak card.
- Soft 18 (A7): the borderline hand. Often a stand or a double against weak cards, and a hit against the strongest cards.
- Soft 19 and 20: stand.
The details by upcard are in the article on soft totals.
Pairs
Pairs are the shortest list, because most of it is two firm rules and a handful of exceptions.
- Always split aces and eights. The reasons are set out in the article on splitting aces and eights.
- Never split tens or fives. A pair of tens is a strong 20, and a pair of fives is better played as a hard 10.
- Split the middle pairs only against weak cards. Twos, threes, sixes, and sevens mostly follow “split when the dealer is weak”. Nines are similar but with a few extra stands.
- Fours are rarely split.
A full walk-through lives in the explanation of pair splitting, and the logic for the tens is in the article on splitting tens.
Step three: attach a reason to every exception
Rote memory fails when you have to recall an arbitrary letter. Reasons are easier. For example:
- You stand on 12 against a 4 because there is a real chance the dealer busts, and hitting risks busting yourself with a fairly high chance.
- You double on 11 because only one card is drawn, you cannot bust, and the most common card value (ten) makes 21.
- You hit a hard 16 against a 10 not because it is good but because standing is not better. The hand is just a poor one, a point discussed in the piece on hard sixteen.
When a cell seems odd, ask what the dealer is likely to do and what your hand can become. That question regenerates most of the chart.
Step four: practise in layers
Learning in the right order matters more than the number of hours.
- Learn the weak and strong groups until you can sort any upcard instantly.
- Add the hard hands and drill only these until they are automatic.
- Add the soft hands, then pairs.
- Test yourself with random hands. Flash cards, a free practice mode, or dealing yourself cards at home all work. Free play mode on a website can also be used, as it carries no stake. Short, frequent sessions help more than one long one.
- Review mistakes, not just scores. A pattern in your errors often points to one category you have not yet understood. Strategy errors can be costly in the long run, so find the pattern before moving on.
A few practice drills of ten minutes can be more effective than a long session of staring at a basic strategy chart.
Know which chart you are learning
Charts differ with the rules at the table. Whether the dealer hits or stands on soft seventeen, whether doubling after a split is allowed, the number of decks and whether surrender is offered all change a few cells. Learn the core chart first, then learn only the handful of changes that match the game you actually play. The article on strategy adjustments covers those variations.
What memorising does not do
Even a perfect memory of the chart leaves the casino with an edge in nearly every standard game. Past hands do not change the odds of the next one, and a streak of good or bad results is not a signal to change your approach. Basic strategy does not cancel variance, so losing sessions will still happen, sometimes for a long stretch.
Only play with money you can afford to lose, set limits before you start, and never chase losses. If gambling stops being enjoyable or starts to cause problems, contact a local support service.
