How these numbers were computed

Our blackjack engine plays out every hand against the exact cards left in the shoe, with the dealer’s exact chances of each final total, and picks the best play for each total over all the hands that reach it. Only splits use a small approximation. Its house edges agree with published combinatorial results to within 0.005% of the bet. Figures assume a fresh shoe every round, like a continuous shuffler; a cut card adds a little to the house edge.
