You hold a hard 6 (no ace counted as 11). The dealer shows a 6. Here is the mathematically correct basic-strategy play — and why.
| Hit ← | -0.0130 |
| Stand | -0.1537 |
| Double | -0.2819 |
| You bust on the next card | 0.0% |
| Dealer 6 busts | 42.3% |
Hit is worth 0.1407 more per unit than Stand. On a $10 bet that is $1.41 handed over every time you get it wrong. Across the 340 situations in this chart it ranks 182nd by expected value — better than 158 of them, worse than 181. 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.
A dealer 6 only busts about 42% of the time — most of the time they'll finish with 17 or better. Standing on hard 6 just waits to be beaten. Even though hitting busts you 0% of the time, improving your hand is the lesser risk against a strong dealer card.
Think of it this way: your 6 almost never wins as-is against a made dealer hand. The hit isn't reckless — it's the only path to a total that can actually win.
