Question on Rule Variation

[tlop]

Assume 8 decks. The standard rule is aces can be split only once, only receive one card, and can not be doubled.

What is the change in EV if they can split and take more than one card?

What is the change if aces can be split and doubled?

What if aces can be resplit to 4 hands?

Hope this question makes sense.

Thanks for your help.

For eight decks, being able to split and re-split aces is worth .072% over a normal game where aces can be split but not re-split.

Being able to hit split aces multiple time adds about .1%

Don't know about double down on split aces, never seen this rule.

This isn't "Super Fun 21" (where you can double down on split aces)?
You get paid even money on Blackjacks, so you still have a bigger house edge than regular blackjack. You are getting paid 3:2 on blackjacks, right?

I believe this is covered in Wong's Basic Blackjack. If nobody has a copy handy I'll look it up when I get home.

Using k_c's software, here's what I get:

For a normal 8D H17 game, the house advantage is .6481.

Allowing hitting split aces will reduce the house advantage to .4684.

In addition to the above, allowing doubling on split aces will reduce the house advantage to .4610.

In addition to the above, allowing splitting aces to four hands will reduce the house advantage to .4006.

I hope I did this right. A little confirmation would be good!

Tlop - From your previous description of the quality of your players, I'm sure you know that offering them more options will give them more opportunities to screw up.

You are using the program correctly. Just input the available rules variations you want and click Calc, which is what you did. If you don't remove any cards and don't input any player or dealer cards you get the full shoe BS EV. If you remove some cards you get the BS EV for that shoe comp. If you input a partially dealt hand you get the BS EV for that. If you input a fully dealt hand you get stand/hit/double/split/surrender EVs where applicable for the shoe comp that is input.

Rules can be varied in a lot of ways.
If it was 8D, H17, Split 2-10 3 times (4 hands), Split aces 3 times (4 hands), 1 card to split aces, no surrender, DAS for pairs 2-10:
Full shoe EV = -.5779%.

Program assumes you must be able double after splitting and also be allowed to hit split aces in order to be allowed to double after splitting aces. (I think there was a thread in which there is a game somewhere in which this isn't the case.)

Thanks for your helpful replies. One last question, what is the change in EV for "Split Rescue," ie letting someone surrender after splitting?

Thanks,

My CA can only handle most common rules variations. MGP, who used to post on this site from time to time, has a CA that handles an amazing number of variations. You might try asking the question on advantageplayer.com as I have seen his posts there fairly recently.
