Hi,
Glad to have found this board! Trying to sharpen up before heading to Vegas for the 1st time.
What's the best play with a pair of 8's against 9, 10 or A with late surrender? Does the count or DAS affect your decision? Thanks for any advice.

against A always surrender if H17, otherwise surrender if +6, otherwise split.
with S17 and against 9, 10 surrender at +2 or above, otherwise split.
with H17 and against 10 surrender if over 2, otherwise split.
with H17 and against 9 always split.
I think you are giving two different strategies or H17 and S17 play against the 9?. Ordinarily conventional strategy against the 9 is the same for H17 and S17. I think there is a discrepancy some place.
This is the kind of mistake I make all the time.
Personally, I was always split against a 9. I surrender against a 10 if I have a non-trivial bet out. That is not mathematically optimal, but it has practical advantages.
I have my max bet out there. The game is H17, no surrender. I have a pair of 8's against the dealer 9 and I stay. The ploppy's yell I have to split and then the dealer busts and they tell me good play.
Was I correct in my play at a TC+6
First, let me again mention that H17 is not a consideration when are facing a 9 up.
Now, Prof BJ shows the index for this play (in 4 decks) at +17 without DAS, and +18 with DAS.
These are not RA indices, and we should expect the4se to be a bit lower. But I am fairly confident that you made the wrong play.
Now please don�t take offense at the next comment. I am really not directing it to you, but to everybody else out there.
This is part of the reason why so many card-counters have negative EV games. They know just enough about counting to be lose more money.
Don�t improvise indices! You Know that you have an edge with the I-18 (or whatever set of indices you have simulated.) Why guess at 30 more indices, which may take your edge away if you guess wrong.
are those given by Brett Harris in his Brh-I (true count) version. So I translated it into Hi Lo by just adding 2 numbers to the count, but he indeed calls for a difference on that one particular play. Brh-I is like Wong Halves, but also counts the 9 as -0.5, thus unbalancing itself.

Split, split, split.
With a ten up, there's a 6 index. Split 88 v T only if less than +6 (and there's no surrender). Maybe that was the cause of your confusion.

that Brett Harris has a different index for S17 v 9 and H17 v 9.
Then one has got to be a typo.
At TC+6, the EV for splitting eights against the nine is -43.6% (DAS assumed) compared to -56.6% for standing. So if your maxbet was $100 you gave away a whopping $13 theoretically speaking.
The only argument for standing would be to avoid consuming cards in order to allow another round but your advantage in an additional round would never come near those 13%.
