Should you split 3s against an 8?
Hit. The book hits two 3s against an 8 through ace and splits against the rest.
Why
Two 3s make 6. Against an 8 the dealer ends on 17 or better 75.6% of the time.
Splitting starts two hands on 3, each one up against the same 8, and each one needing its own bet. The book splits 3s against a 2 through 7. Against an 8 it hits the 6.
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 3s against an 8. With a single deck and double after split, the book splits instead. Every other rule set plays it the way the app's table does.
