Hard 18 vs dealer 8: the verdict
The verdict is stand. Against a dealer 8, hard 18 does best by letting the dealer take the risk of busting.
The numbers
| Action | Win | Push | Lose | EV per $1 |
|---|---|---|---|---|
| Stand | 37.3% | 35.9% | 26.7% | +0.106 |
| Hit | 19.4% | 2.1% | 78.5% | −0.591 |
| Double | 19.4% | 2.1% | 78.5% | −1.182 |
Why stand is correct
A dealer showing 8 busts 24.5% of the time, and that bust chance is doing the work here: standing wins 37.3% of hands without ever risking your own bust. Drawing a card would improve the total sometimes, but the bust risk and the hands you’d ruin cost more than they gain.
For context, a dealer 8 finishes on 17–20 about 68.6% of the time, on 21 6.9%, and busts 24.5%. 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 hit instead of stand costs about $1743 per 100 such hands at $25 a hand (−0.697 EV per dollar). The genuinely expensive error here is double: −1.288 per dollar, or roughly $3220 per 100 hands at the same stakes.
Does the rule set change it?
No — stand holds across every common configuration: Vegas Strip, Atlantic City with late surrender, H17 games and European no-hole-card tables all agree here.
