| DoubleBest | +0.484 | — |

Hard 11 against a 2 is a doubling hand: you are a favorite to improve to a strong total on one card, and the dealer's 2 is weak enough that putting more money out is worth it.
Doubling returns +0.484 per unit against +0.245 for a plain hit. The extra 0.240 is the value of the doubled bet on a hand where you expect to win more often than not.
Hitting wins the hand often enough that players forget to put the extra bet out. Skipping the double leaves money on the table. Just hitting instead of doubling costs 0.240 per unit versus the correct doubling. Over a few hundred of these hands, that is real money handed back.
Same hand, different table conditions. The correct play holds unless noted.
| Table condition | Correct play |
|---|---|
| 6 decks, stands soft 17 (baseline) | Double |
| 6 decks, hits soft 17 | Double |
| Single deck, stands soft 17 | Double |
| Double deck, stands soft 17 | Double |
| No surrender offered | Double |
The play is stable: double is correct across deck counts, the soft-17 rule, and whether or not surrender is offered.
