lelo: EV and variance of game?
Rules: 6D, OBO, S17, D2, full ES, DAS.
Resplit: yes, to max 4 hands, including aces, but only on your initial hand. example: you split 22 and get a 2 on your right split hand. then you can resplit. but no rs if you get a 2 at your left split hand. split aces get 1 card, surrender after split is allowed.
What is the EV of such a game and how much is the difference to "normal" resplit?

Norm Wattenberger: Resplit right hand only
That rule made me curious. I get .03% penalty for Resplit right hand only.

ES: Re: EV and variance of game?
What is OBO? I suppose that full ES means es against both ace and 10.
I would run a sim of the game with and without resplitting and take the mean of the two EVs. Resplitting adds little to EV; nrs takes little from it. Resplitting allowed is much more common. The original Atlantic City rules, which were set by the NJ Casino Control Commission, did not include resplitting. I think this was not intentional or done with little forethought. Resplitting is now an optional rule in AC and most casinos allow it. The original AC rules were es, das, s17, doa and 4 or 6 decks, which gave the BS player a n EV of +0.1%.
The basic stratgey for es was little known. It includes surrendering 5, 6, 7, 12, 13, 14, 15, 16 (incl. 8-8) and 17 against an ace. Many players think 17 is a good hand, no hand under 12 shoud be surrendered because you cannot go over 21 with one hit and that 8-8 should always be split. The flip side is that some players were surrendering 12 and 13 against a 7 or 8. The casinos still wanted esr removed and the Commission removed it without mandating lsr or any other compensating favorable rule. Lsr was removed more than a year before Ken Uston won his NJ Supreme Court case that ended backing off and barring in AC, so he cannot be blamed for ending esr. He even managed to have it reinstated for about a week because of a procedural error made by the Commission in removing it. Uston led a demostration on the Boardwalk to reinstate surrender. I participated in it.

ES: Re: Resplit right hand only
Your post must have appeared while I was typing my longer post. What is OBO? Does CV Data alllow simming resplit right hand only? I suggested simming rs and nrs and taking the mean of the two. Is this equivalent, and, if not then why not?

Original bet only lost with dealer BJ. The standard US rule.

I have it as an internal rule; which is to say it can't be used in the commercial version. I have to find space on the screen to make it user accessible.

Yes that is very close.

lelo: most interesting point:
OBO= original bet only, i.e. only 1 bet is lost if you double or split and dealer gets BJ
full ES is indeed ES against any card, including Ace. A lot of casinos are just ES10, i.e. ES against a 10 but not against A.
I understand that this RS-rule is worth nearly half of "normal" RS (exept the rare case when you get a resplit card on both hands).
Something i have not seen published yet: What is the typical variance of an ES game, or equivalent: the Kelly quotient? And if the game is just ES10, but no surrender against Ace?
