Black Jack Appendix 5
The following table displays
the player's expected return, assuming basic strategy, the dealer does not have
a blackjack, and the dealer stands on a soft 17. These tables were based on a
combinatronic model and an infinite deck. Other rules assumed are that the
player may double after a split, infinite resplitting except for aces, and draw
only one card to split aces. Based on these rules the house edge is 0.5093975%.
