7,7 (pair of 7s) vs dealer 5: the verdict
The math is in: split. Two hands of 7 beat one 14 against a dealer 5 — split them.
The numbers
| Action | Win | Push | Lose | EV per $1 |
|---|---|---|---|---|
| Split* | 46.3% | 5.9% | 47.8% | +0.100 |
| Stand | 41.6% | 0.0% | 58.4% | −0.167 |
| Hit | 31.7% | 4.5% | 63.8% | −0.321 |
| Double | 31.7% | 4.5% | 63.8% | −0.643 |
* 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 5. Split, each new hand starting from 7 wins 46.3% — enough that two of them (EV +0.100 across both) beat the best single-hand line at −0.167.
For context, a dealer 5 finishes on 17–20 about 47.5% of the time, on 21 10.8%, and busts 41.6%. 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 $668 per 100 such hands at $25 a hand (−0.267 EV per dollar). The genuinely expensive error here is double: −0.743 per dollar, or roughly $1857 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.
