4/4 v. 6 - 6D - TC 10 ?
I think this might be a double down situation even if the rules allow DAS. I'm using AO2. Anybody know the correct index number for this BS deviation?

CVBJ has the indices and it says split >= 0, and then double hard 8 vs 6 at >= 5.
Logically split is a better option since DAS might give you the opportunity to get even more money out on the weakest dealer up-card there is. If you double you are done, where with split you might get more opportunities.
Others may disagree...
As far as I know,at a Hilo TC of +10, it's still slightly better to split with DAS .It's not really worth remembering an index here.It would be about +11.
Also against a 5, I would always split rather than double.

I had to look it up.As a principle,I don't memorize any indices greater than 10 because they occur too rarely.
that splitting is better here. The 6 up is likely a 16 with a big + count, and the hit card will also likely be another 10. So I want max money out on a big + count, and splitting seems to be a better choice. I will always have at least 2x my normal bet out, and might get to split again, or double on one or more of the split hands, to further improve my expectation.
Of course, in a SD game, one might worry about splitting and eating the deck back to neutral before the dealer plays, since every big card drops the TC significantly when playing SD. But I've always looked at splitting here as the best play, marginally if NDAS, but with DAS it seems (to me at least) to be significantly better.
Hopefully you will get a math-guru (mathprof??, cac??, etc??) type answer as I'd be interested in whether "gut feel" is correct here or not...

Not to worry. There is just as much chance that the TC will climb as well as to fall. However, it is certainly true that the RC will fall back toward zero.
Splitting will certainly eat more cards. If your trying to eek out another round before the shuffle, that could play a big part in the decision of whether to double or not if close to the index such as +9 or +10 rather than the actual index # at what is apparently +11.
I understand the theory. :) It is just that the "practice" sometimes forgets to "follow the book". :) Can you remember a time when you split 10's, got a couple of 10's, 3rd base hit and took a 10, and now you are at something like -2 for the TC, with the dealer sitting there with a 6 up. :)
I play by the book, but I certainly remember the cases where the book fell on me... Some of those books are pretty big and pretty heavy...
However, I firmly believe that just the oposite happens to us and we get our azzes saved just as often.
Look at it this way. Let's assume the composition of the remainder of a deck is as follows:
4 of hearts, 5 of c, 5 of s, K of d, J of d, K of s, Qs, 10c, 10s, Jh & a 10h.
With this scenario, we have a high count situation. If we mix these cards a gazillion times, there is still just as much chance of us or the dealer getting a 5 of clubs as there is of getting a Queen of spades. So not necessarily are the big cards going to fall first and then leave the small ones for the dealer.
Splitting takes precedence over doubling.
Where DAS is not allowed, you do not split fours against anything.
Where DAS is allowed, my respective Main Count index for splitting fours versus a six is -6. That would equate to a Hi-LO true count of about -2( I don't have the A02 indexes handy.).
With a high enough index, you could then double the hand if you drew another four if the rules do not allow you could not re-split your hand any further. The Hi-Lo index for doubling hard eight versus a six is about +3.

I realize that. But what if the TC is +11 or more?
For TC up to +17, I get split significantly more favorable than double for 44 vs. 6, see EV table below for 6D, DAS, S17. H17 also favors split. This is for Omega II, don't remember if the point values were different between AO2 and Omega II.
I get an index for split vs. hit of -4 for S17 (for H17 lower than -8) so any deviation from BS for this play would be really rare.
