Soft 17 (A,6) vs dealer Ace: the verdict
The math is in: hit. Against a dealer Ace, drawing another card carries the best expectation for soft 17 (a,6).
The numbers
| Action | Win | Push | Lose | EV per $1 |
|---|---|---|---|---|
| Hit | 34.4% | 13.2% | 52.4% | −0.180 |
| Stand | 16.7% | 18.9% | 64.5% | −0.478 |
| Double | 31.2% | 10.8% | 58.0% | −0.537 |
Why hit is correct
Standing here wins only when the dealer busts, and a dealer showing Ace busts just 16.7% of the time — the other 83.3% they make a hand and your total loses on its own. Hitting risks going over, but the math nets out ahead: 34.4% wins versus 16.7% for standing, and a better expected value overall.
For context, a dealer Ace finishes on 17–20 about 75.6% of the time, on 21 7.8%, and busts 16.7%. 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 hit costs about $746 per 100 such hands at $25 a hand (−0.298 EV per dollar). The genuinely expensive error here is double: −0.358 per dollar, or roughly $894 per 100 hands at the same stakes.
Does the rule set change it?
No — hit holds across every common configuration: Vegas Strip, Atlantic City with late surrender, H17 games and European no-hole-card tables all agree here.
