Default Doubling or hitting with 11 versus a dealer 10

For a single deck game I have found, over a period of many times, that basic strategy that suggests doubling with an 11 versus a dealer upcard of 10 has -- for me -- been a losing strategy.

I seem to lose more hands than I win.

Again, I am talking a single deck game here.

Is the basic strategy decision to double with the 11 rather than merely hitting it a very close call?

Thanks in advance for your replies.

Not a close call. For a $10 bet, hitting instead of doubling costs you about 57 cents.

No, it's not even close. The EV for hitting is 0.133 and the EV for doubling is 0.202. Doubling is much more profitable than hitting. But the probability of winning is still pretty slim. You have about a 51% chance of winning and a 42% chance of losing, so the short-term results may be very frustrating.

Doubling 11 vs. 10 has always a greater expaction than hitting. Take a look at this tables http://www.bjmath.com/bjmath/ev/1ds17.htm

In 6-deck games...

On whether to Double or Hit on 11 vs. Ace depends on whether dealer hits a soft 17.

If dealer hits a soft 17 (H17) then Double, otherwise Hit.

What the hell does it have to do with DAS? DAS changes the way you split, not the way you double.

Relax. I've corrected my original post.
I meant to show the difference in Hit/Double depends on whether the game is H17 or S17. I mistakenly said DAS.

Also, this difference is for 6 deck games.
In single or double deck game, you would double 11 vs. Ace with either rule.

The short answer is yes to always double down 11 v Ten when using basic strategy.

You have to realize two key concepts (a) basic strategy is the "most accurate" at the beginning of the deck and (b) not all 11's are the same.

While basic strategy works anywhere in the deck, it's most accurate at the start of the deck. Later in the deck, while basic strategy may still advise you to double down, it may be wrong EV play as confirmed by card counting (11 v T is an indice play) because the composition of the cards have changed, i.e. the count is negative because a lot of tens have already been dealt.

Also, if your 11 is made up of 9,2, then you have one less 9 in your favor and that something to consider. In contrast, if your 11 is made up of 6,5 then you have one less 6 OR 5 for your 11, thus reducing your chances of nailing a 16 or 17.

According to Fred Renzy. You are a 6 to 5 favorite to win the hand, meaning you will win 6 and lose 5. The reason to double is that, at the end of the 11 plays you will have twice as much money by doubling. Think of the play like you would, if your favorite football team could use 11 players against 10 for a third and long.
