Hi.

Came over a weird BJ variant where it was allowed to pay your initial wager once again and draw one extra card after a double.
The rule must be advantagius to the player as far as I can understand, but how is the basic strategy and what is the house edge?

Rules:
6 Deck
Double On Any,
Triple On Any double
Resplit To 4 Hands (No Aces)
Aces split only once and get only one card each
Blackjack Pays 3:2
Dealer Stands On Soft 17
Dealer Does Not Peek For BJ
Surrender on 10

What happens if you double, then triple, and the dealer has BJ- do you lose only your initial bet or everything?
Same question if you split four times.
Can you double and triple after splits.
Both the edge and your strategy would depend on these things.
It's what you do and not what you say If you're not part of the future then get out of the way

Hi geirov, welcome to the forums.

The questions billryan gave are pretty improtant to figuring out the house edge/etc. Also, I believe I've seen this as a blackjack variant or known bet. Apologize I don't recall the name of the game/rule, but search the blackjack threads and you should come across it.
Playing it correctly means you've already won.

Hi Bill.

SInce dealer does not peek for BJ you loose everything if dealer has BJ.
Split is up to four splits and you can double and triple after splits.

Thanks Romes.

I've been searching, but most tripling seem to mean triple instead of double your bet when doing a normal double.

Those odds and strategy are described under the wizard of odds, but are not like the strategy here. I think this triple rule will let you double on as low as 5 against 5 or 6, but that is just a gut feeling, I have.

Found two basic charts:
One from AceTwo:
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.

And another chart a bit different I also found:
DOUBLING
5 v 5-6 Double
6 v 4-6 Double
7 v 3-6 Double
8 v 2-7 Double
9 v 2-8 Double
A3-A6 v 3-7 Double
A2 c 2-7 Double
Treat 4,4 as 8 ie Double v 2-7 and No split
TRIPLING (based on correct doubling)
All hards hands upto 11
All Soft Hands upto S17
All Soft 18 Hands except v 2

So I assume one of the above charts are optimal or maybe a chart combining the two. I must admit I did not consider the possibility of tripling after hitting 3 after doubling on 9 or 2 after doubling on 10 against 8.... That is not intuitive..... ;-)
