Take another 8 out of the deck. Since this question was submitted, a player held the dice for rolls on May 23, in Atlantic City.

This is a typical question one might encounter in an introductory statistics class. It is more a matter of degree, the more you play the more your results will approach the house edge. Take the dot product of the probability and expected value over each rank.

Following this rule will result in an extra unit once every hands. Here is how I did it. From my section on the house edge we find the standard deviation in blackjack to be 1.

Streaks, such as the dealer drawing a 5 to a 16, are inevitable but not predictable. So standing is the marginally better play. Add values from steps 4, 8, and The hardest part of all this is step 3.
