You hold Ace-7 — a soft 18, meaning the ace still counts as 11. Dealer shows Ace. The correct basic-strategy play:
| Hit ← | -0.0929 |
| Stand | -0.1002 |
| Double | -0.3628 |
| You bust on the next card | 0.0% |
| Dealer Ace busts | 16.7% |
Hit beats Stand by 0.0073 per unit staked. Small, but it is the same small edge in every shoe you ever play — and it compounds over a lifetime of hands. Across the 340 situations in this chart it ranks 213th by expected value — better than 127 of them, worse than 212. Expected value is per unit staked, computed for multi-deck, dealer stands on soft 17, double after split allowed. The model and the code are published as data.
The beauty of soft 18 (Ace-7): you cannot bust — the ace simply drops to 1 if the card is big. Against a dealer Ace (only 12% bust chance), your current total isn't good enough to stand on, and doubling doesn't pay against a card this strong. Free shot at improving: take it.
Soft hands are where most casual players leak the most: they play them like hard totals and miss every profitable double. Learning the six soft-total rows of the chart is the fastest win-rate upgrade there is.
