Deals soft 18 (Ace-7) against a dealer 2 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 | +0.124 | — |
| Double | +0.121 | -0.003 |
| Hit | +0.063 | -0.061 |
| Surrender | -0.500 | -0.624 |
With soft 18 (Ace-7) you already hold a total the dealer has to beat, and the 2 is weak enough that letting the dealer draw is better than risking your own hand. The dealer busts 35.5% of the time showing a 2, while hitting would bust you 0.0% of the time.
Standing is worth +0.124 per unit; the closest alternative, doubling, comes in at +0.121. That 0.003 gap is the price of taking an unnecessary card.
Players hit soft 18 (Ace-7) out of fear of the dealer's 2, but the 2 is exactly why you stand. Hitting costs 0.061 per unit versus the correct standing. Over a few hundred of these hands, that is real money handed back.
