When the dealer hits soft 17, some weak soft 17s improve. The rule generally increases the house edge and changes several player decisions, including some doubles and surrender cells.
| Rule | S17 | H17 |
|---|---|---|
| Dealer soft 17 | Stands | Takes another card |
| Player effect | Generally better | Generally worse |
| Chart compatibility | Use S17 chart | Use H17 chart |
Compare the cost, not only the label
Keep wager volume and the edge denominator the same on both sides. If one figure uses only the initial wager and another uses all money ultimately at risk, convert them before drawing a conclusion.
For a $1,000 block of comparable action, each one percentage point of house edge represents $10 of theoretical loss. That is a long-run average, not a forecast for one session, but it makes small-looking rule differences easier to value.
How to use this comparison
Confirm that the posted rules match the assumptions above. A familiar game name does not override a different payout, dealer procedure, pay table, qualification rule, commission, or denominator. If one material rule differs, return to the full game guide and model that version separately.
Table-check procedure
- Photograph or write down the complete pay table and mandatory wagers.
- Identify which outcomes push, qualify, receive commission, or trigger bonus awards.
- Match the exact variant to a documented record or calculator.
- Compare expected cost at the amount of action you realistically expect to play.
