99 v. A (and KO indices)

Hi guys, this is my first post, although I've been browsing the forums for the past couple years. I love this board, tons of information learned, and entertaining as well. On to my question:

The game is DD, H17. At what KO count do you split 99 vs. an ace showing? I recently was dealt this hand and didn't know what to do, but felt "adventurous." If I can recall correctly, I took insurance around +5, dealer unfortunately did not have blackjack, I think the count stayed the same, so I decided to split them. I am quite sure this is the right play, but just want to double check the exact index.

And while we're on the subject, does anyone have a chart with KO indices (particularly for splits and soft doubles, which are not included in the KO Blackjack book)? I believe I did a search awhile back, and resulted in at least a couple of different charts. Thanks in advance for your help!

..as I recall, a complete set of charts exists in the Green Chip archives. If I remember correctly, the poster's name was Dr. Org.

Nines indeed should be split against a dealer's TEN at high counts.

My guess is that using K.O. it would be a True Count of +3 or +4

Ace's should be hit against a dealer's TEN at very low counts.

My guess is that using K.O. it would be a True Count of -6 or -7

Paired 8's and 7's [when facing a dealer 10] should be surrendered at a modest plus count where Late Surrender is offered. As surrender is not available to most players, this is nearly a moot point.

I do not use a one-level count but I am interested in what K.O. has to say.

You are probably referring to the GC post of 25 Nov 00 by Dr. Org.
The title is "KO COMPLETE RA CHARTS". As the title implies, these are risk averse charts. As far as I can see, there is no index for splitting 9,9 vs 10.
I've checked several sources for multi-deck DAS indices and don't find an index for that play.
