Rare BJ Rules - Redouble after double
What is the BS strategy for this rules - it looks player have to double more aggressively and redouble more frequent !
Assumed : 6 deck, DAS, DOA, S17, ENHC, ES10, SPL1(ace pair), SPL3(other than ace pair), BJ pay 3 to 2, split ACE only draw one card.
After double, total bet on table = 2 units.
After redouble, total bet on table = 3 units(NOT 4 units !).
Quote: ssho88The special BJ rules - Redouble after double. After double, player are allow to put a bet amount equal to original bet amount and draw a card and stop. That mean after redouble, there are total four cards and total 3 x original bet amount for that particular hand.

I can't tell you the whole strategy, because I do not know it. But I can give you some of them. In addition to regular BS:
5-8 v. 4-6--Double
4,4 v. 5,6--Double, do not split
9 v. 2, 7--Double
A,3-5 v. 3-6--Double
A,2 v. 2-6--Double
Redouble on 12 v. 7
Quote: SonuvabishRedouble on 12 v. 7
How can that be right? A redouble is essentially just a double for less, which can never be right if basic strategy is not to double.
An initial double might be correct, but I don't see how a redouble could be right. Am I missing something?

Yes. You normally can hit a 12 versus a 7. In this case, you either can stand on 12 versus a 7, or increase your bet by 50% to get that one extra card.

I edited it not to double 8 v. 2.
Because you have to double the penalty for standing, and halve the penalty for doubling. If you do the math, it is actually beneficial to re-double against a 2, 3, and 8 as well, and there are probably situations where it is best to double a hard 13. I only included the 12 v. 7 because that is the best hard double and they are all neg EV, high variance plays.

Why would I wanna get more money on the table on a 12 vs a 7?

Because you aren't actually doubling, you are betting 50%. The only alternative to not doubling 'for less' is to stand. Any AP would normally take the card. If you want to just gamble and increase the house's edge and not follow the proper strategy, then that's why you wouldn't--like 99% of all players, 80% of whom claim to be experts.

Ohhh, good point, you can't take the extra card unless you redouble.
Quote: KellynbnfThe reason you might redouble a stiff hand is the same reason at casinos that allow you to double, but not hit, split aces you might double a -EV hand just so you can get the additional card.
Correction--The 12 v. 2,3 do not check out as good re-doubles. The 8 does check out though. In response to Kelly: That's partially correct. Such rules typically bring in money to the casino n player errors, sometimes as in the case of surrender, more than offsetting the theoretical benefit to the player. However, if you are implying that the re-double (not simply doubling) the 12 v. 7 is improper, then you would be incorrect. In addition, for any AP, it would be pretty good cover to make the correct play. I doubt any dealer or pit boss would consider this to be proper strategy. This is a very quirky and interesting rule that I enjoyed analyzing. I am jealous of the OP and wish him the best of luck!

Redouble on 12 v. 7
The game desdribed is known as Triple (not Redouble)
The strategy that I have is as follows (similar to above):
DOUBLING
5-6 v 5-6 Double
7 v 4-6 Double
8 v 2-7 Double
9 v 2-8 Double
A4-A6 v 3-6 Double
A2-A3 c 2-6 Double
Treat 4,4 as 8 ie Double v 2-7 and No split
2,2 and 3,3 v 8 Split
TRIPLING (based on correct doubling)
All hards hands upto 11
12 v 7,8
13 v 7
All Soft Hands upto S17
All Soft 18 Hands except v 2,3
The Tripling rule helps by around 0,41%. It makesthe standard game desribed (ENHC, ES10) which is around -0,26% become around +0.15%.
This is a very goood game.
It is similar EV with full ES game. Full ES is though still better in EV and in lower variance.

I would surmise that your strategy is more accurate. Most of mine were educated guesses. I checked a few of them to make sure the math made sense. But it is basic strategy to double soft 18 v. 3, so you must mean only if it is a triple, correct? Very interesting that you would split against 8s in case you get to 9, which you would only risk doubling on because you're not dead if you get a deuce. Next job: index numbers.
Where is this game?

The strategy I quote is different for Doubling and Tripling.
So yes S18 v 3 is correct Doubling but incorrect Tripling.
Index numbers: I know these have been calculated but I do not have them. But I think there is no need to learn indeces.
I have played this game in 2-3 different casinos.
And my Double with 5 raised a few eyebrows.
My Triples for 12 v 7,8 also made me look like a 'moron'.
I also tried uncessfully the 'Triple for less'. If allowed a lot more stiffs become correct 'Triple for less'.
