so, it's not always a metter of assuming the card is the average card in the deck. Even though 8 is close to the statistical average of a deck of cards, you want to find what card is most likely. You want to look for mode, not mean. The mode of the deck is of course 10. Even though the deck averages to 8, the chance of the card actually being an eight is far lower than the chance of it being a ten.

hit 16 stay on 17 the same as the house you will win more

TEN!

Discounting aces, the total value of the cards in a blackjack deck is 4x(2+3+4+5+6+7+8+9+10+J+Q+K) = 336. Divide that by 48 cards, and you have "7.0" Depending on how you count aces, the resulting average could be between 6.5 and 7.3. I don't see where "8" came from, but "10" seems rather cautious.

I play blackjack..and I go with the unseen card is likely 10..the way to leave is doubling on your next bet when you lose one..then knowing when to leave when you are up!

I don't agree but You know what they say when you ASS U ME...
You make an Ass of U and Me..

I would like to go headsup in blackjack against anyone who follows this rule of thumb. One CAN win a blackjack but it takes hours of playing and your winning depends entirely upon your betting.

As a retired casino shift boss, Mr. Brenner assumption is entirely wrong. Only 7% of the cards in the deck are 8's while 30% of the cards are ten counters. Therefore, one must assume that any unseen card is a 10.

Mr. Brenner, do you kids know your loosing their inheritance to stupid gambling rules of thumb?

The correct assumption is that an unseen card is a 10value. I agree with Rita below.

Norman, you need a hobby, gambling is not productive, it is a game of chance, and the chances are YOU LOOSE.

I am glad to read this one but my way is a lot simpler ...I dont play blackjack...I never play at another mans game

I strongly suggest NOT following this suggestion  you can pick up a blackjack basic strategy card for a dollar and do a lot better than this.

The actual weighted average of a deck, OTHER THAN THE ACES, is 7. Because there are only 4 aces in the deck, whether they are counted as 1 or 11, the weighted average would vary from 6.5 to 7.3. Someone would have to run some simulations to see what ass

Using that rule will cost you a lot of money. For instance, if you have 15 and the dealer is showing a 3 and you assume he has an 8 under, you must hit the 15 because he has a good chance of beating 15 when he hits. The proper strategy is to stand and l

Because there are more cards with a 10 value...assume the hidden card is 10.
Rita  20080116
Assuming unseen cards are 10s IS the rule of thumb for blackjack. Ask any dealer. Factoring in the lower cards won't help you because, the purpose of assuming unseen cards (which, really, the dealer is the only one you are concerned with) are tens is so
Joel Parent  20080110
8 is close to 10 but provides a good weighted average estimate based on the deck. There are certainly more tens in the deck based on face cards, but you have to factor in the effect of the other lower cards. That's how i think 8 is the right value. Fas

I agree with Evan via Sammy. What's the reasoning behind 8 and not 10?
Sammy  20080109
i agree with evan!
Evan Christensen  20080108
Assume any unseen card has a value of ten!
