9,9 (pair of 9s) vs dealer 3: the verdict
The verdict is split. Two hands of 9 beat one 18 against a dealer 3 — split them.
The numbers
| Action | Win | Push | Lose | EV per $1 |
|---|---|---|---|---|
| Split* | 51.2% | 7.8% | 41.1% | +0.242 |
| Stand | 50.9% | 13.0% | 36.1% | +0.148 |
| Hit | 17.6% | 2.8% | 79.6% | −0.620 |
| Double | 17.6% | 2.8% | 79.6% | −1.240 |
* 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 3. Split, each new hand starting from 9 wins 51.2% — enough that two of them (EV +0.242 across both) beat the best single-hand line at +0.148.
For context, a dealer 3 finishes on 17–20 about 51.1% of the time, on 21 11.5%, and busts 37.4%. 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 split costs about $235 per 100 such hands at $25 a hand (−0.094 EV per dollar). The genuinely expensive error here is double: −1.482 per dollar, or roughly $3705 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.
