Soft 18 (A,7) vs dealer 6: the verdict
Basic strategy says double. Against a dealer 6, this hand is strong enough to put double the money on the table.
The numbers
| Action | Win | Push | Lose | EV per $1 |
|---|---|---|---|---|
| Double | 56.1% | 6.9% | 37.0% | +0.382 |
| Stand | 58.9% | 10.6% | 30.5% | +0.283 |
| Hit | 56.1% | 6.9% | 37.0% | +0.191 |
Why double is correct
Doubling wins almost exactly as often as hitting (56.1% vs 56.1%) — the difference is you have twice the money riding on a favorable spot. Against a dealer 6 (bust chance 42.3%), that extra bet is the whole point: EV +0.382 doubled beats +0.191 hit.
For context, a dealer 6 finishes on 17–20 about 48.0% of the time, on 21 9.7%, and busts 42.3%. Those dealer outcomes are the same no matter what you hold — the whole game is choosing the action whose distribution fits them best.
What the mistake costs
Choosing stand instead of double costs about $245 per 100 such hands at $25 a hand (−0.098 EV per dollar). The genuinely expensive error here is hit: −0.191 per dollar, or roughly $477 per 100 hands at the same stakes.
Does the rule set change it?
No — double holds across every common configuration: Vegas Strip, Atlantic City with late surrender, H17 games and European no-hole-card tables all agree here.
