7,7 (pair of 7s) vs dealer 4: the verdict
Basic strategy says split. Two hands of 7 beat one 14 against a dealer 4 — split them.
The numbers
| Action | Win | Push | Lose | EV per $1 |
|---|---|---|---|---|
| Split* | 44.4% | 6.2% | 49.4% | +0.011 |
| Stand | 39.4% | 0.0% | 60.6% | −0.211 |
| Hit | 30.9% | 4.7% | 64.4% | −0.335 |
| Double | 30.9% | 4.7% | 64.4% | −0.670 |
* 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 4. Split, each new hand starting from 7 wins 44.4% — enough that two of them (EV +0.011 across both) beat the best single-hand line at −0.211.
For context, a dealer 4 finishes on 17–20 about 49.4% of the time, on 21 11.1%, and busts 39.4%. 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 $554 per 100 such hands at $25 a hand (−0.222 EV per dollar). The genuinely expensive error here is double: −0.680 per dollar, or roughly $1701 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.
