Help need some index numbers for double deck

Can't seem to find any index numbers for H17, DAS, DA2 double deck.

Specifically,

When the count is high, do I still split 6's vs 7, and 7's vs 8?  

I recently had a very high count, and had 6's vs 7.  I didn't know what to do, since BS says to split, but common sense told me not to.  I ended up losing both hands.


At what count do I stay, if I'm supposed to?

Any help would be greatly appreciated!!

The difference between splitting and hitting, 7,7 vs. 8 is minimal all the way from +3 to +14, at least.  It's a completely "flat" index, with virtually no extra edge accruing to the player as the count rises.  Bottom line:  split, but no big deal if you don't.

Wong gives no index for not splitting 6,6 vs. 7.  I think you should do it all the time, barring nothing left in the deck but tens!

Thanks for the response and the advice, Don!  Glad to know that I wasn't doing anything wrong by splitting up until now.  :)

 

Something about all these figures dont add up....

Oh that's right all these fractional instances "that do not matter" .5% here .7 percent there... .09 percent in a million other places. 

Eh they dont matter do they....

Lets just not individualize things in an over all game. 

Lets add them all together and bibidy bobidy boo...you got the makings of a pretty crap system.

You could always tell for your yourself.  

Or you could say that all these figures the wizard, don, norm, doghand, Al, Wong...Or agent orange himself Mr. Smith by way of Norm...the pirate of them all are 1...they haven't yet figured out that all these small odds and fractionalize numbers dont make up a whole pie.  Or 2 their keeping them for themselves.  

So you decide being the masters of odds and variance...What do you think the odds are that they got their odds all wrong.  

I wonder what the odds are that I am

Them (and me among them) wrong? 0% chance.

You wrong? Hard to say since you haven't actually posted any details. My guess? 100% chance.



 

Is there much of a penalty using single-deck index numbers in a double deck game?

I am using Hi-Opt I with a side count of aces.

If you have them, you're better off using 4-deck or 6-deck numbers for DD than using SD.  SD is somewhat of a unique game, and its indices less resemble DD than do multi-deck ones.

Don,

I’ve read this a lot and therefore bought the cards from Kennith Smith for the different indexes for each game. The SD didn't look that different from the DD.  Are these cards accurate?  Besides the insurance index, what are the most important ones that are different than DD?

Bottom line, is there anything you can add to why SD is unique. Some new SD have opened near me and I’ve been playing them. No, they are not 6:5, but they only let you double on 11 and 10, and only split once. I’ve simmed them on cvcx and they still look like good games. I know PE is more important on SD so I want to make sure my index plays are correct. 

Thanks!

Keep High Low (HL) for the one deck game with the side count Am6c (Ace minus Six) Count.  Use HL + Am6c for insurance, HL + 2*(Am6c) for hit/stand hard 16 v 7, 8, 9, T and use HL for betting and all other strategy changes .

Here are some selected one deck indices derived from Effects of Removal for one deck (from Don Schlesinger's Black Jack Attack, 3rd edition) using Least Squares Line and Proportional Deflection both of which produce identical results.  

One deck indices for HL, Hi Opt 1, HL + Am6c for insurance and HL + 2*(Am6c) for hard 16 v 7, 8, 9, T,  CC = Correlation Coefficient.  HL + 2*(Am6c) has tag values of + 1 for Ace, 2, 3, 4, 5, tag values of zero for 7, 8, 9. and tag value of -1 for 6 and Tens.  So Ace are courted as + 1 and sixes as -1 in HL + 2*(Am6c) where Am6c = Ace minus Six count which is what is required for hard 16 v 7, 8, 9 and T.  So for example, stand on hard 16 v 9 if HL + 2*(Am6c) >= 3*dr (2.6 is rounded up to 3) with CC = 83.9% where dr = decks remaining. 

HL + Am6c is the Gordon count where 2, 3, 4, 5 have tag values of +1 and Tens have a tag value of -1 which is what is used for insurance.  Insure if HL + Am6c >= 2*dr for the single deck game. 

Stand on hard 16 v T if HL + 2*(Am6c) >= 0,  Stand on hard 16 v 9 if HL + 2*(Am6c) >= 3*dr and Stand on hard 16 v 7 and hard 16 v 8 if HL + 2*(Am6c) >= 6*dr.  Insure if HL + Am6c >= 2*dr and then use HL for all other strategy changes and for betting.  dr = decks remaining.

BJANAYST, thank you for your detailed answer to my question. This is what I was looking for. I had to read it several times but I think I now understand it.

I have looked at usung Hi Opt 1 with a side ace count on single deck, but I like your approach better. Thanks!
