What is the dealers average final hand in blackjack for ALL the various number of decks and whether they hit or stand on soft 17. Ive heard from 18.23 up to 18.56.



If they stand there average hand is 17 because they are just staying with 17. if they hit there average hand is 18.5 because 18 or lower is normally a losing hand in blackjack on average and 19 or higher is usually a winning hand in blackjack. The dealer on any given hand will get a

You know enough to know everything that's needed to be known for nearly anyone.

Are you taking the average of all non-busted dealer hands? Because I don't know how you'd "average" in all of the 22+ hands.

What a great question! I started up to type out the quick, obvious answer, but then I realized............ I didn't know what it is.

Yes, non busted hands. This is an important factor and I forgot to mention that part.



Then that doesn't tell me crap. If all the players don't bust, and the dealer doesn't bust, then his ending hand will average 18.?
That tells me nothing of any use.

I'd compare it to people saying "The Patriots win their games by an average of 9 points..." Does that include the games they lost? Does it take points away in those cases? Probably the only way to have quasi-meaningful data would be to say, the dealer breaks X%, and in the (100 - X)% that the dealer doesn't break, the average final hand is Y.

The average value is
(17+18+19+20+21)/5 = 19
Something tells me, you meant to ask about the expected value, not the average.
To compute the expectation, you need to weigh the numbers by values from Wizard's Appendix 2.
For example, for 6 deck S17:
(0.152487 * 17 + 0.146201*18 + 0.14035*19 + 0.188478*20 + 0.076507*21)/0.704023 = 18.844205
