10,10 (pair of 10s) vs dealer 5: the verdict
The verdict is stand. Against a dealer 5, 10,10 (pair of 10s) does best by letting the dealer take the risk of busting.
The numbers
| Action | Win | Push | Lose | EV per $1 |
|---|---|---|---|---|
| Stand | 77.9% | 11.3% | 10.8% | +0.670 |
| Split* | 59.3% | 7.1% | 33.6% | +0.513 |
| Hit | 6.9% | 0.8% | 92.3% | −0.854 |
| Double | 6.9% | 0.8% | 92.3% | −1.709 |
* win/push/lose shown per split hand; EV covers both hands per one initial bet.
Why stand is correct
A dealer showing 5 busts 41.6% of the time, and that bust chance is doing the work here: standing wins 77.9% of hands without ever risking your own bust. Drawing a card would improve the total sometimes, but the bust risk and the hands you’d ruin cost more than they gain.
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 split instead of stand costs about $395 per 100 such hands at $25 a hand (−0.158 EV per dollar). The genuinely expensive error here is double: −2.379 per dollar, or roughly $5948 per 100 hands at the same stakes.
Does the rule set change it?
No — stand holds across every common configuration: Vegas Strip, Atlantic City with late surrender, H17 games and European no-hole-card tables all agree here.
