    R7 Indices

    Someone a few years back posted additional red seven indices based upon KISS indices. But some of what he posted we know are not correct. Below are the indices he posted from KISS on page 155 of the Blackjack Bluebook— converted to an IRC of -12 for a Red Seven 6D shoe:
    8 vs. 5 @ +4
    8 vs. 6 @ zero
    9 vs. 2 @ -2
    9 vs. 7 @ +4
    10 vs. 10 @ +9 (semi-risk averse)
    10 vs. A @ +7
    11 vs A @ -2 for S17: @ -9 for H17
    12 vs. 2 @ +4
    12 vs. 3 @ zero
    12 vs. 4 @ <-10
    12 vs 6 @ <-15 for S17: never for H17
    13 vs. 2 @ -14
    15 vs. 10 @ +6
    16 vs. 10 @ -6
    16 vs. 9 @ +9
    A/7 vs. 2 @ -2
    A/8 vs. 4 @ +4
    A/8 vs. 5 @ -2
    A/8 vs. 6 @ -2 for S17: @ -9 for H17
    10/10 vs. 5 @ +8
    10/10 vs. 6 @ +8
    Insurance @ +4

    Some of these we know don’t make sense because Snyder himself says insurance is taken at +2 in a shoe game, not +4. 15 v T is +2, not +6. 12 v 2 is +2, not +4.

    These are just ones that stand out to me. I’m hesitant to use his other ones knowing that these others are blatantly wrong. Does anyone know a good resource one could find additional Red Seven Indices? The ones Snyder publishes with the book are 16 v T @ 0, 15 v T @ +2, insurance at +2, 12 v 3 @ 0, 12 v 2 at +2. But I would like to learn additional ones such as when to double an 8, when to stand on 14, 15 and 16 v 8 and 9’s.

    The original thread is here: https://www.blackjackinfo.com/commun...indices.23690/

    Much appreciated

    Fred Renzey, who is the author of Blackjack Bluebook II, posted those indexes. I will trust him. By the way, Arnold Snyder's indexes are all simplified.

    Arnold published something like four versions of R7 over the years.

    Ok now I’m confused by the last two comments. These weren’t Fred Renzey’s indices (unless that was the poster).

    The poster had used the KISS indices and then attempted to move them over to R7 by his own calculations.

    The index plays I said Snyder posted are universally accepted. But as I said I would like to learn more. I don’t think I would use his 15 v T one when Snyder makes it very clear at +2 you stand.

    Fred renzey created kiss. Kiss and Red7 are basically the same count. The "conversion" of kiss indices to Red7 is subtracting 21 from the kiss indices, since kiss IRC is 9. Not sure why Snyder's indexes are not as accurate, as the other commenters, posted but I'd definitely trust renzey's. You could always simulate both sets of indexes in cvdata to see which one gets better results.

    I have a hard time saying Snyder made a mistake when we’re applying a different system to Snyder’s R7 with indices sort of guessed, and saying it’s wrong. I’m assuming this is best guess work? I mean doubling 8 v 6 shouldn’t be too hard to figure out.
