8,8 (pair of 8s) vs dealer 9: the verdict
Basic strategy says split. Two hands of 8 beat one 16 against a dealer 9 — split them.
The numbers
| Action | Win | Push | Lose | EV per $1 |
|---|---|---|---|---|
| Split* | 33.5% | 11.2% | 55.2% | −0.405 |
| Hit | 21.6% | 5.9% | 72.5% | −0.509 |
| Stand | 22.8% | 0.0% | 77.2% | −0.543 |
| Double | 21.6% | 5.9% | 72.5% | −1.019 |
* win/push/lose shown per split hand; EV covers both hands per one initial bet.
Why split is correct
Played as a single total, this hand is weak against a 9. Split, each new hand starting from 8 wins 33.5% — enough that two of them (EV −0.405 across both) beat the best single-hand line at −0.509.
For context, a dealer 9 finishes on 17–20 about 71.1% of the time, on 21 6.1%, and busts 22.8%. 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 split costs about $260 per 100 such hands at $25 a hand (−0.104 EV per dollar). The genuinely expensive error here is double: −0.613 per dollar, or roughly $1533 per 100 hands at the same stakes.
Does the rule set change it?
No — split holds across every common configuration: Vegas Strip, Atlantic City with late surrender, H17 games and European no-hole-card tables all agree here.
