Deals a pair of 10s against a dealer 6 in the trainer, graded live.
Per unit bet, six decks, dealer stands on soft 17, computed by the engine.
| Option | EV / unit | vs. best |
|---|---|---|
| StandBest | +0.703 | — |
| Split | +0.566 | -0.137 |
| Surrender | -0.500 | -1.203 |
| Hit | -0.852 | -1.555 |
| Double | -1.704 | -2.408 |
With a pair of 10s you already hold a total the dealer has to beat, and the 6 is weak enough that letting the dealer draw is better than risking your own hand. The dealer busts 42.0% of the time showing a 6, while hitting would bust you 92.2% of the time.
Standing is worth +0.703 per unit; the closest alternative, splitting, comes in at +0.566. That 0.137 gap is the price of taking an unnecessary card.
Players hit a pair of 10s out of fear of the dealer's 6, but the 6 is exactly why you stand. Hitting costs 1.555 per unit versus the correct standing. Over a few hundred of these hands, that is real money handed back.
Same hand, different table conditions. The correct play holds unless noted.
| Table condition | Correct play |
|---|---|
| 6 decks, stands soft 17 (baseline) | Stand |
| 6 decks, hits soft 17 | Stand |
| Single deck, stands soft 17 | Stand |
| Double deck, stands soft 17 | Stand |
| No surrender offered | Stand |
The play is stable: stand is correct across deck counts, the soft-17 rule, and whether or not surrender is offered.
