    Differentiating Running Count Indexes from Indexes < 0

    I finally discovered the option to Use Running Count with Zero Index in strategy creation. However, I can't always differentiate between an index at 0 and an index at -1.

    For example, here I'd want 16v10 and 12v4 to be RC indexes, but 13v2 to only trigger at a true -1.

    In the surrender menu it appears to be possible, am I missing something?

    (And, before anyone gets their panties in a knot, these surrender indexes are for ES10)

    PitBoss321,

    I don't know the answer to your question.

    I have a question for you, though: why would the ES index for 14 vs. X be a reverse index? Just off the top of my head, I would think that you should surrender this more frequently as the count increases.

    Also note that 7-7 vs. X is set to ES always: since presumably you aren't planning to split, why shouldn't both of these plays have the same index? Is this a SD game?

    I just double checked those, I made a dumb typo, 14vX and 15vA are supposed to be 0+, not -1 -. As for 77vX, I just reran CVIndex to make sure and it does have a different value for some reason. Its index is -1+, which for me means always.

    There are several online blackjack hand calculators, so you can just use them to generate the play deviation index easily for any situations. What is this software you are using? Is it CVCX?

    Hmm, why would you want to do that?

    I'm curious what hand calculators you've found online, I don't know of any that produce index plays.

    I'm using CVIndex software

    To the best of my understanding, those are the correct plays. I'm basing the RC plays on Colin's charts (https://www.blackjackapprenticeship....07/BJA_H17.pdf) as I haven't found any other sources that confirm or deny the info.

    And just to clarify, my understanding is that 13v2 is a stand at any 0 TC, whereas 16vT is a stand only at positive RC.

    No, there is no such thing. You may be confused as what a deviation index is.
