Hard 12 vs dealer 7: the verdict
The math is in: hit. Against a dealer 7, drawing another card carries the best expectation for hard 12.
The numbers
| Action | Win | Push | Lose | EV per $1 |
|---|---|---|---|---|
| Hit | 35.5% | 7.6% | 56.8% | −0.213 |
| Stand | 26.2% | 0.0% | 73.8% | −0.475 |
| Double | 34.5% | 5.7% | 59.8% | −0.507 |
Why hit is correct
Standing here wins only when the dealer busts, and a dealer showing 7 busts just 26.2% of the time — the other 73.8% they make a hand and your total loses on its own. Hitting risks going over, but the math nets out ahead: 35.5% wins versus 26.2% for standing, and a better expected value overall.
For context, a dealer 7 finishes on 17–20 about 66.4% of the time, on 21 7.4%, and busts 26.2%. 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 $656 per 100 such hands at $25 a hand (−0.263 EV per dollar). The genuinely expensive error here is double: −0.294 per dollar, or roughly $735 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.
