error in ko full indices in the book?

[arrando]

It says in the ko book for ko full 1D to double 8 vs 5 on +5 or above. However, doubling the 8 vs. 5 is basic strategy on the wizardofodds blackjack calculator for the same rules as the ko book gives (noDAS, H17). How does this make sense?

+8 is a bit better. Card counting is not basic strategy. It has to include all counts and penetrations.

http://www.qfit.com/book/ModernBlackjackPage262.htm lists the single-deck strategy, but starts the RC at -1 instead of 0.

That still doesn't make sense because normally, at any penetration for single deck, the count should be anywhere from 0 to 4 on average. I assume that basic strategy accounts for the "on average" so if you should double 8 vs. 5 at +5 or +8, then this tells me most of the time basic strategy for this play is wrong.

Oh I see, these are risk averse indices, right? So the wizard of odds basic strategy is not as risk averse?

 

[QFIT]

No, the KO book is not RA. Yes, Modern Blackjack is RA. But, that's not the difference. BS takes into account the cards in your hand and the dealer card. So, basic strategy is not the same as counting strategies.

Oh got it, makes sense now. Also, you recommend for 1d splitting 10's v 6 only at 13? Any time you would split 10's against a 5?
