Worth of playing on these rules?

Hi! In town where I live has two blackjack tables and I want to know are these rules good enogh to play.

There are 6 deck in use.
Can only double hands 9, 10 and 11.
Can't double after split.
Stand on soft 17 (A-6).
No resplit after spilt.
On push bank wins but when both have blackjack or have 21 total I get my money back.
All I know about shuffle is that cards are shuffled by hands not in machine.

i really hope you aren't serious. ties 17-20 lose and you are talking of upwards of 9% house edge. stay far far away.

So I just ask how much true count has to be that I get even with bank?

[Kaabee]

if you don't know that this game is unbeatable, you have no business counting cards.

Well then if shuffle tracking is possible is there any chance to beat the casino?
