You're dealt a pair of 7s. The dealer shows a 10. Split or play it as one hand? Basic strategy answers:
| Hit ← | -0.4663 |
| Stand | -0.5404 |
| Split | -0.6289 |
| Double | -0.9383 |
| You bust on the next card | 46.2% |
| Dealer 10 busts | 23.0% |
Hit is worth 0.0741 more per unit than Stand. On a $10 bet that is $0.74 handed over every time you get it wrong. It is also the 9th worst spot of the 340 hands in this chart. Expected value is per unit staked, computed for multi-deck, dealer stands on soft 17, double after split allowed. The model and the code are published as data.
A dealer 10 is too strong to justify splitting 7s — you'd just be doubling your exposure with two weak hands. Play the pair as a normal total of 14 instead: hit.
