Three hand types
Hard totals, soft totals, and pairs use different charts because aces and split opportunities change the risk of the next card.
A hard total is fragile once it reaches the stiff zone from 12 through 16. A soft total has an ace that can absorb one bad card. A pair can become two separate hands, which means the decision affects both expectation and variance.
Dealer upcard pressure
Dealer 2 through 6 are weaker upcards, so you stand more often with stiff hands. Dealer 7 through ace are stronger, so weak totals usually need improvement.
This pressure idea explains much of the chart. You are not standing on 13 against a dealer 4 because 13 is strong. You are standing because the dealer is under more pressure to break.
Practice method
Train hard totals first, then soft totals, then pairs. Speed matters only after accuracy is stable.
- Start with dealer upcards 2 through 6 so the “dealer weakness” pattern becomes obvious.
- Move to dealer 7 through ace after you can explain why stiff hands usually need help.
- Use training mode for immediate feedback, then review the stats page for recurring mistakes.
Fallback actions
Some strategy cells depend on table rules. Double-if-allowed means double when the table permits it, otherwise use the fallback action. Surrender-if-allowed works the same way. BlackjackPro shows these moves as combined labels so the chart stays accurate across rule settings.
What basic strategy does not do
Basic strategy does not guarantee a win on the next hand. It removes avoidable decision errors over many hands. That is why the trainer tracks accuracy separately from bankroll: the decision and the result are related, but they are not the same thing.
