Stand on soft 17, no surrender. Rows = player total. Columns = dealer up-card.

What "basic strategy" actually minimizes

Basic strategy is the loss-minimizing play under standard rules. It does NOT overcome the house edge (about 0.5% with good rules) — you still lose money long-term. But it reduces the loss compared to gut-feel play by ~2-4×.

Who uses it

  • Recreational players who want to play "the right way".
  • Educators teaching decision-making under uncertainty.
  • Card counters who need to know the baseline they're deviating from.

Limitations

  • We implement a "Stand on 17" common-rules chart. Side-rule variations (surrender, insurance, etc.) require additional rules.
  • Card-counting deviations (Illustrious 18 + Fab 4) are NOT included — the chart is for non-counters.
  • This is for educational use only. We are not advocating gambling — see Disclaimer.
