I did this the other night at a local casino and the dealer pointed out to me that I had a 19 and was I sure that I really wanted to do that. I said yes, she looked at me like I was stupid and then dealt the card. I ended up with an 8 for a total of 17 and she ended up making 18. Does anyone know the EV of standing versus doubling? Thanks.
Single Deck - Doubling A,8 V 6?

In H17 SD game, double A,8 vs 6 is basic strategy. When the dealer gave you the stupid look, you could have said "Don't you even know the basic strategy for the game you deal?" LOL!
The EV is:
A,8 vs 6 stand .447
A,8 vs 6 double .466
If you are lucky enough to be playing a S17 single deck game, double is the correct move if the count is positive. (In fact, if you only double this hand in positive counts in the H17 game, you are better off.)

Rational for my response.
You have a dealer working against you. She is questioning the plays you make. You want a dealer to deal the cards, not second guess and call attention to you sometimes not making the 'correct' ploppy play. Especially in single deck where a lot of play variations are made.
Sometimes a smart remark at the beginning of a session lets a dealer know, "Keep your mouth shut and deal" and you don't have to be yelling "Checks Play" real loud if you want tips.

You said something very interesting -- that one should only double A,8 v. 6 in positive counts. I want to second this.
The point is that while this move generates a little more EV, it definitely adds a lot to your SD. Thus, what we want is to wait until we get a little more EV, thus reducing the ration EV/SD to a manageable quotient. This is what we really want in life. For example, a job with a steady paycheck has a SD=0, so the ratio is infinitely positive. That is the best source of income. The more SD you have with respect to your EV, the larger the bankroll you need and the wilder will be the fluctations.
This concept generates what are known as "Risk Adverse Indices" -- meaning one should make the play not just when the EV says to, but rather wait until the ratio of EV/SD says to.

Thanks for the replies! The game is S17 and the cut card is placed anywhere from 50% to 60% deep. They've always dealt 2 rounds to a full table (7 players), I've had 3 rounds dealt a few times with 5 players, but of course it only happens in negative counts. It was tough to get a seat the first few times I went, but I believe most of the ploppies have moved back to the 6 deck shoes. Too much shuffling for them I guess. I've been able to spread 1 to 4 with no heat. I made a few cover plays each session the first few times I played there (when pc's were watching), but do not anymore. I will continue to play there in short durations until I get that tap on the shoulder. There are 2 other places nearby that have single deck, but one has a $25 min and I don't know about the other. I don't have the bankroll (yet) to play quarters.
