How high must the true count be to double down soft 21?
(I don't see it on the illustrious 18)
Quote: anonimussWas it a 6/5 game? And most casinos I remember won't let you double down on A/TJQK
doesn't matter/splits don't count as BJ
Btw: our blackjacks pay 3:2.

I can't direct you to a site or publication but a trusted friend once simmed it for Hi- Lo and got +12 versus a 5 or 6.
According to my humble calculations, doubling down on soft 21 is a better buy than standing versus 5 and 6, if true count (hi-lo) is 8 or greater. This is true for 6D, S17 game. For different rules (number of decks) the count could be slightly different.
Hope this helps!

In other words, if the casino allows it (which mine doesn't - the second you hit 21 at my casino it's an instant stand, BJ or no BJ) and you get a 3:2 BJ, the deck has to be hot enough to burn holes in the table AND you need an assurance that the dealer is damn near certain to bust in case you DON'T draw a face card in order to even THINK about doing something this maddening.
Mathematically, it makes sense - in the rarest of the rarest of the rarest scenarios that would bring the entire MIT blackjack team to orgasm just from hearing the count. But out of 100 people who would attempt this, given how rare it is, probably 20-30 are experts, the same number are people who probably should give up blackjack for life, and the rest are sleep-deprived, drunk, or both, and think, "Cool! Pretty colors!" and put out more chips.

Not certain I understand your response.........if I split 10's and draw an Ace, I can't double down? Is that what you are saying?
Just want to clarify- I think I know the casino (based on your name). Thanks buddy!
AFAICT that is the only situation in which this question is relevant.
EDIT: Duh, I forgot the case of split 10s drawing an ace. With a high enough count, a double down in that situation would be warranted (as the consummate pros have pointed out before me). Always remember to refresh the tab you left open from last night, kids.
Not in this case.He is talking about doubling on soft 21 not on a blackjack.Quote: anonimussWhether blackjack pays 3:2 or 6:5 makes a difference.

Thanks for the calc! Damn that is quite a high requirement, but man it'd sure be a shocking play if the right condition comes
Quote: IbeatyouracesYou can find the double on split aces rule in northern Michigan. The catch is you can't hit, just double or stand.
Interesting rule. I have never played with it.

The profit-maximizing index for doubling soft 21 against a six is around +7 or +8. Cardinal rule is to double the index for splitting 10s against the appropriate dealer upcard. The risk-averse index is to never double a soft 21 under any circumstances. I have never done this, and likely never will.

If you split 10s and get an ace, it's end of hand, same as if you get a blackjack. 21 means end of hand, you stand, soft or hard.
And yes, Hollywood Columbus.

Thanks for the reply. That's a very odd rule, indeed.
The dealer will typically have to call out a play like this and make sure the floor supervisor acknowledges it. This also goes for doubling a breaking hand and splitting tens.
