I18 and Other Indices

I just wonder how many of you guys stick to I18 only, being the most important indices, and how many actually use more than these basic ones?

I've learned the I18 and stick to them as a part of my regular play. Actually, in my case, it's more like Sweet 16, because I don't split 10's, for known reasons.

How much more advantage can one potentially gain by using more indices, like doubling 8, or A8, for example?

Learn as many as you can handle. Your strength lies in your diversity. :laugh:

BTW split 10's, it will make you look like an idiot just as easily as the other. Never give up ev moves.

I use about 50 indices(Risk Averse)

One of those days,you'll be scratching your head on the way home from casino,wondering what's the right play on a hand like:
S17,6D,DAS,DOA,80%pen.
Hilo TC@+6,late in the shoe,you're dealt 2,2 vs 8:eek:

Additional indices won't get you alot of EV,but every bit counts.
It's Always Good to Know:)

P.D.

I'm not positive about this, but intuitively it seems like splitting a low pair against a dealer 7+ would actually be worse at a positive count (dealer is less likely to bust and you're more likely to wind up with stiffs.) I'm not sure that even splitting deuces against a 7 would be the correct play with those rules at a TC of +6.

Then you wouldn't use my RA indices (not Hilo).
I split 2,2 v 7 always and 2,2 v 8 at +3

If the 2 is the dealers Ace then deuces never looses for me too :grin:.

EDIT: the EV probability charts says:

Hand Standing Hitting Doubling Splitting Probability
2,2 vs 7 -0.47462 -0.08883 -0.94924 0.008675 0.00044
2,2 vs 8 -0.51125 -0.15679 -1.02249 -0.17676 0.00044

So vs 7 its a winning move
vs the 8 its ever so slightly worse then hitting (maybe a good cover play) so maybe +3 adds a bit in your favor

Very interesting, and part of the reason why I love playing BJ is because of the counter-intuitive plays such as this (I couldn't help but laugh when a ploppy flipped out at me when I hit 16v7, then stood on 5-5-6v10 a few hands later.) Just goes to show why you should always trust the odds over your own instincts. I would be interested to see to logic over splitting 2,2 against 8 at +3, though.

How about this one:
Hand Standing Hitting Doubling Splitting Probability
3,3 vs 8 -0.51057 -0.21918 -1.00114 -0.23058 0.00044

Splitting is just slightly worse then hitting. I split at +3 here too.

Maybe good cover and a defensive play?

splitting 2's and 3's Vs 7 or 8 are Defensive split.
By doing so in a +count,EV(split)>EV(hit)
Also a good cover

Doing things like splitting 2's vs 8 in a high count may be good cover but if the critters know how to count, they're not going to be stupid enough to be fooled by this me thinks. They'll note that you hit the A7 vs the dealer 9 earlier (a very good indication of a solid basic strategy player at the least as most people won't hit in this situation) and then when they see you doing abnormal stuff like splitting 2's vs an 8 or hitting 12 vs a dealer 6, they're going to get a bit suspicious. At least I would if i were in their shoes but maybe I'm wrong and most of them really are that dumb.
Here's a good question for you. If you're in a +1 TC, and you have 4,4 vs the dealer 6 in a 6 deck S17 game, do you split them or double ;) I wonder how the EV compares in that situation.

Split :)
I know 8 vs 6 @TC+1 is double...But
The Order of Decisions ;)
