Should you double soft 19 against a 6?
Double. If you can't double, stand. The book doubles soft 19 against a 6 and stands against the rest.
Why
Soft 19 is a fair hand to stand on, and the book stands on it against every dealer card but a 6. Against a 6 it doubles instead.
The double isn't about building a better hand. It's about having twice the bet out when the dealer goes over 21, which with a 6 showing is 43.9% of the time. And a soft hand can't break on one card.
When the answer changes
At the app's table (six decks, the dealer hitting soft 17, double after split and late surrender) the book doubles soft 19 against a 6. With two, six or eight decks and the dealer standing on soft 17, the book stands instead. Every other rule set plays it the way the app's table does.
