Should you double 8 against a 6?
Hit. The book hits 8 against every dealer card.
Why
A 6 is weak, but not weak enough to double 8 into. With a 6 showing, the dealer goes over 21 43.9% of the time.
Doubling locks you into one card for twice the bet, and from 8 only one of the 13 ranks, an ace, reaches 19 or better. Take a card and keep your choices open. At the app's table the book never doubles 8.
When the answer changes
At the app's table (six decks, the dealer hitting soft 17, double after split and late surrender) the book hits 8 against a 6. With a single deck, the book doubles instead. Every other rule set plays it the way the app's table does.
