What should I do with Soft 19 (A,8) vs Dealer 8?
Optimal Play: Stand
When you have Soft 19 (A,8) and the dealer shows 8, the mathematically optimal play according to basic strategy is to stand. This means you should keep your current hand and let the dealer play.
Why Stand?
With a soft 19, you have a strong hand that doesn't need improvement. The Ace gives you flexibility, but your current total is favorable enough to stand.
Expected Value
Standing maximizes your expected value here. The dealer is likely to bust or end up with a worse hand than yours.
Alternative Actions
Alternative actions for this hand against other dealer cards include: Double Down. However, against an 8, stand is optimal.
