basic stragery of this new blackjack rule

and house edge

8decks
dealer bj and player 21 is push
no hole card
early surrender except dealer ace
double any two
das
spilt up to 4 hands
dealer bj eat all double and spilt
suit 777 pay two to 1 note include split hands

ace can respilt

dealer bj eat
double and spilt
but if you got 21
this is still push

who can give me the
correct b.s.
including advance stragery

the wizard has help for finding the HE for these things, but [as someone pointed out to me] not necessarily for changes in BS.

perhaps instead of being specific, which would probably entail some work, somebody can kind of come up with a rule of thumb for adjustments in BS with special rules.

i think bs change
for double 11 vs ace

also i want to know
how large tc
should double
11 vs 10

Is it a H17 or S17 game? Clearly for American style this is a BS changer for 11vA. If it's H17 I would think you still double it all the same. Either way you could look up the indexes in the I18, again found on the Wizard's site: https://wizardofodds.com/games/blackjack/card-counting/high-low/

Notice I'm going to make you use those links to find your answers =).

its s17

and the link
u provide i find b4

no answer for
dealer bj push player 21

i use mobile see the variation
there even cannot see
push 21 bj is what advantage for player

so when should i double 11 v 10??

This is close.

Due to the payout bonus, it's probably advantageous to hit rather than split 7's, except against a dealer 6.

If a player 21 pushes a dealer natural, that's an advantage for the player. See Player 21 vs. dealer blackjack is a push

I see it as always double 11 vs 10, because a 21 will push, rather than lose all, in the most pessimal circumstance.

but the chance of
dealer bj is 1 /13

and player 21 is 4/13

others not 21 vs bs still kill both bets

another one tell me only
over tc -0.5 is worth to double 11vs dealer ace

so is it always double 11 vs 10

... and if you don't make 21, you lose all when the dealer draws to 21. This is present in more ordinary rules.

I see no particular difference here between a dealer 2 card 21 and a dealer 3 card 21, since either will push a player 21, but take a player 20.

Since the dealer 2 card 21 ("blackjack", "natural", etc) doesn't trump a player 3 card 21, I see no special disadvantage. The extra disadvantage would be when you double your 11, make 21, and the dealer draws a ten on his ace and takes all. Since it pushes in this game, I don't see it as a disadvantage.

Someone with stronger math may jump in and correct that.

I think there is a moderate disadvantage for doubling 11 vs A in this game vs a hole card game with peek. In the hole card game, while you don't have full knowledge of the hole card, you know it's not a ten.

but for the b.s.
if dealer bj lost all doubling
we should not double
11 vs dealer 10

These are for 6 decks (but it should not differ by much for 8d)
Without Special rule, 11 v 10 has following Evs:
Hit +3.10%
Double +0,78%
Difference 2.32%

Player 21, Dealer BJ will happen approximately:
4/13 x 1/13 = 2.37% of the times.
When it happens it saves 1 unit for the Hit and 2 units for the Double
Hit becomes: 3.10% + 2.37% = 5.47%
Double becomes: +0.78% + 2 x 2.37% = 5,52%.

The results of the above oversimplification are very close with Double just sliughluy better.

BUT we did not take into account that with Hit you can get 21 in 3 or more cards, so for hit the increase is not 2.37% but more.
I would estimate around 3%, so Hit is 3.1% + 3% = +6.1%.

So the decision is still to Hit 11 v 10.
But the Index will be lower than the normal game, I would estimate a TC=+1 (Hi Low) for the index that it becomes Double.
