Complete Blackjack Basic Strategy Chart

This is the reference chart used by the trainer on the home page. It is written for a common multi-deck blackjack game: dealer stands on soft 17, doubling is allowed on any first two cards, re-splitting is allowed, and blackjack pays 3:2. If your table uses different rules, a few border decisions can change, but this chart is the right baseline for most beginner practice.

Original illustrated strategy chart grid with marked blackjack decision cells.

Read each table by finding your hand on the left and the dealer's upcard across the top. The cell tells you the basic-strategy action: H = hit, S = stand, D = double if allowed otherwise hit, Ds = double if allowed otherwise stand, and P = split. The trainer converts these chart cells into live feedback so each mistake includes the exact reason for the correct play.

Hard Totals

A hard total has no Ace counted as 11. These hands are the easiest to learn because the logic is mostly about bust risk. Low totals hit because they cannot win by standing. Hard 13 through 16 stand when the dealer shows 2 through 6 because those dealer upcards bust often enough to justify patience. Against 7 through Ace, those same hands usually hit because the dealer is more likely to make a strong total.

The hardest hard-total pattern for new players is hard 12. It looks fragile, but the chart still hits 12 against dealer 2 or 3 because those upcards are not weak enough to justify standing. It stands against 4, 5, and 6 because those are the dealer's most bust-prone cards. This is exactly the kind of border case the trainer is designed to drill until it becomes automatic.

Soft Totals

A soft hand contains an Ace counted as 11. Soft hands are valuable because they let you take another card without immediate bust risk: if the draw would push you above 21, the Ace becomes 1 instead. That flexibility creates many double-down opportunities against dealer 4, 5, and 6, especially with soft 15 through soft 18.

Soft 18 is the hand most people misplay. It feels like a safe stand, but against a dealer 9, 10, or Ace it is not strong enough; basic strategy hits. Against dealer 2 through 6 it often doubles because the dealer's weakness plus your flexible Ace makes the extra unit profitable over time. Against 7 and 8, standing is enough.

Pair Splitting

Pairs are checked before hard or soft totals because splitting changes one hand into two starting hands. Some rules are simple: always split Aces and 8s, never split 10-value cards, and never split 5s. The other pairs depend heavily on the dealer's upcard. In general, you split more often when the dealer shows a weak card and less often when the dealer shows 8, 9, 10, or Ace.

The pair chart explains two common surprises. First, 5s are not a split hand; they are a hard 10, which is one of the best double-down hands in blackjack. Second, 10s should stay together. Splitting a made 20 gives up one of the strongest positions in the game for two uncertain hands.

How to Practice This Chart

Do not try to memorize every square at once. Start with the patterns that occur most often: hard totals, especially 12 through 16. Once those feel natural, switch the trainer's practice focus to soft hands and drill the Ace cases. Finish with pairs, where the always/never rules remove a lot of the chart from memory.

  1. Hard totals: Practice until you instantly know when to stand against dealer 2 through 6 and when to hit against dealer 7 through Ace.
  2. Soft totals: Pay special attention to soft 18. It is the best test of whether you are reading the chart rather than trusting intuition.
  3. Pairs: Memorize Aces, 8s, 10s, and 5s first, then learn the dealer-upcard-dependent pairs.
  4. Review mistakes: Use the trainer's hand history and explanations to identify the situations you keep missing.

When you miss a hand in the trainer, do not just note the correct action. Ask which rule group it belonged to: low total, stiff hand, dealer bust card, soft double, or pair split. That category-level understanding is what turns the chart from memorized trivia into usable decision-making.
