16 vs. 10 and 12 vs. 3 are the other two powerful ones. I believe that in most games those two plays plus insurance give you more than every other index play put together.Billy C1 said:How much does proper indices play add to your game? Realizing that insurance is the biggy, what about other indices plays?
Thanks!

That can't be right. Where are the doubling indices? They're worth far more than crazy plays like 16 vs. 7 and 13 vs. 4.FLASH1296 said:Theory of Blackjack, 6th ed. by Peter Griffin gives reliable

On page 30 is the 1 deck table.
On page 229 is a 4 deck table.
On page 230 is a 6 deck table.
Utilizing only the SIX DECK table:
16 vs 10 is worth 47/1000 %
Insurance is worth 38/1000 %
15 vs 10 is worth 13/1000 %
13 vs 2, 12 vs 4, and 12 vs 6 are all worth 12/1000 %
14 vs 10 and 12 vs 5 are both worth 9/1000 %
13 vs 3 and 12 vs 3 are both worth 8/1000 %
16 vs 7, 16 vs 9, and 13 vs 4 are all worth 6/1000 %
The rest are virtually worthless.
NOTE: In a single deck game perfect Surrender decisions is worth a powerful .16%.
That figure drops as the number of decks increases; BUT the actual value to a Card Counter
is twice or thrice as much - as surrender decisions effect large bets disproportionately.
In Blackjack Attack, Schlesinger, points out that Griffin's numbers are flawed because they are all based on a flat bet amount. Most counter will have significantly more money on the table at the departure point for insurance making that by far the most important play with a gain of 117/1000 of a percent, followed by 16vs 10 at 53/1000 and 15 vs 10 at 37/1000 and then the splitting of 10's vs 5 and 6 at 17/1000 of a percent. All of these plays with the exception of 16 vs 10 are weighed more heavily because they occur when there are larger bets an the table, much like your reasoning as to why surrender decisions effect large bets disproportionately.FLASH1296 said:Theory of Blackjack, 6th ed. by Peter Griffin gives reliable

I've looked in "Professional Blackjack" and there is no index for this play in Hi-Lo. I think it would be such a high TC (+9 or higher?), with such a low probability of it ever happening, it's not worth bothering with it - hit it every time. Flash, where did you get your figures from?ycming said:Someone have a chat with correct indicies play following the count?
I use the following, but it doesn't seem to have 14 vs 10 ?
