Available Games Ranked by DI

The following games are ranked by DI, though win rates by unit are listed as well. I used CVData, which is much faster and easier to use than CVSim, and CVCX, which is similar to BJRM and also does sims on custom bet spreads. My play strategy was KO Preferred. I used the KO 6D strategy for four decks. My bet strategies were 1/2/4 at 1/2/3 for SD, 1/2/4/8 at 1/2/3/4 for DD, 1/2/4/8/12 at �4/-2/-1/0/2 for 4D, 1/2/4/8/12 at �4/-3/-1/1/4 for 6D, and 1/2/4/8/12 at -4/-3/-2/-1/2 for 8D, with no cover.

Games with win rates below 1.0 are denoted by an X. In some cases denoting an X is based on interpolation rather than an actual sim. I did sims on most games listed by CBJN as available in Nevada. Though CBJN does not indicate Rule or 6 or 7, I added those two pen levels for SD. �DI� refers to Don Schlesinger�s �Desirability Index� (see Blackjack Attack).

Excellent data.
Would you mind running this sim 50m hands? ( I expect a neg return).

London Rules:
6 dck, 75% Pen, S17, DAS, D 9,10,11 only, European No Hole Card(ENHC,Even Money offered when Dealer shows Ace up.

bet strategy(start -20):
-4 (1), -3 to -1 (2), 0 to 3 (4), >=4 (8)

Playing strategy:
standard basic strategy with following departures:
+4 or more stand 16 v9, stand 15 v10, stand 12 v2, stand 12 v3
+3 or more take insurance(even money)
-4 stand 16 v10
NEVER SPLIT 8/8 or A/A versus dealer ACE

(BTW anyone with experience of UK play - can you confirm this splitting rule is optimal for UK ? IN UK dealer BJ beats ALL doubles and splits. player BJ on 1st 2 cards stands.

Thanks
Regards

Sorry, forgot a couple of other playing departures:

+4 or more: double 9 v 2, 9 v 7, 10 v 10, 11 v 10

thanks
regards

Sorry to post a dumb question, but...

What does di stand for?

Thanks

Desirability Index = 1000 X win rate per hand / Standard Deviation per hand. A method of comparing games with different win rates and variance on an equal footing.

I always thought that had to do with GIRL WATCHING.

I wonder how one could derive what bet spread maximizes this DI ratio for a particular game, without resorting to sims and trial & error?

"Blackjack Attack" by Don S. Chapter 10 starting at page 187 shows ways you can out perform the win rate suggested by the DI. DI is just a starting point, a uniform measure, to compare games.
