Last update: March 12, 2002

Effect of Removal

The following table shows the effect on the player's expected value by removing one of the given card for each deck. For example if the removed card is a seven then each deck would have three sevens, as opposed to the usual four. These numbers were based on infinite deck, dealer stands on soft 17, double on any two card, double after split, split only once, and strategy adjustments for the changed deck compostion.
