Should you split 7s against an 8?
Hit. The book hits two 7s against an 8 through ace and splits against the rest.
Why
Two 7s make 14. Against an 8 the dealer ends on 17 or better 75.6% of the time.
Splitting starts two hands on 7, each one up against the same 8, and each one needing its own bet. The book splits 7s against a 2 through 7. Against an 8 it hits the 14.
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 two 7s against an 8. With one or two decks and double after split, the book splits instead. Every other rule set plays it the way the app's table does.
