8,8 (pair of 8s) vs dealer Ace: the verdict
Basic strategy says split. Two hands of 8 beat one 16 against a dealer Ace — split them.
The numbers
| Action | Win | Push | Lose | EV per $1 |
|---|---|---|---|---|
| Split* | 33.4% | 13.5% | 53.1% | −0.394 |
| Hit | 20.9% | 6.4% | 72.7% | −0.517 |
| Stand | 16.7% | 0.0% | 83.3% | −0.667 |
| Double | 20.9% | 6.4% | 72.7% | −1.034 |
* 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 Ace. Split, each new hand starting from 8 wins 33.4% — enough that two of them (EV −0.394 across both) beat the best single-hand line at −0.517.
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 hit instead of split costs about $308 per 100 such hands at $25 a hand (−0.123 EV per dollar). The genuinely expensive error here is double: −0.640 per dollar, or roughly $1601 per 100 hands at the same stakes.
