Thoughts on this game

[BLACKJACKSKI]

Hello, first post after a couple of years lurking.

I´m having problems comparing my local game vs some variations of 21 seen on the web to find the approx house edge. Mainly because of the different payouts and the fact that the 10s are in the deck.

The game is "casinos name 21"

No hole card
CSM Dealt
6 Deck H17
3:2 Player BJs, push against dealer BJs
Surrender allowed except vs ace
Double with any 2 cards
Double after split
Resplit aces
Split to 4 hands
Can´t double any total if its not the original 2 cards
No redoubling, rescue any of that spanish 21 stuff
Only lose original bets vs dealer BJ

Using the wizard of odds calc I get a 0.28721% house edge.

Now you also get the following bonuses/side bets and the bonuses apparently are better than the regular spanish 21 ones.

Bonuses without sidebetting (you get paid as soon as you hit the bonus, then the dealer hits their hand)

678 offsuit 3:1
678 suited 5:1
777 offsuit 5:1
777 suited 20:1
5 card 21 2:1
6 card 21 3:1
7 card 21 5:1

Sidebets

Regular insurance 2:1
Insurance vs 10 10:1
Over 13 1:1
13 10:1
Under 13 1:1

Soft hands lose all 3 "13 bets"

I am getting the impression that this game just seems to good to be true.
The one thing I may be missing would be if they removed 1 ten, 1 jack, 1 queen and 1 king instead of the 4 tens


Ploppy disclaimer:
There are no shoe dealt games available anywhere near me and I just like to play like about once a month, and play basic strategy, I´m definetly not an AP.

So which is it?

Sorry, I meant more than 2 cards, not necessarily the original hand,

You can split 8s, get a 3 and double.
You are stuck hitting if you have 5-2-4 vs 6

This one line should make it a long term losing game.

Bonuses without sidebetting (you get paid as soon as you hit the bonus, then the dealer hits their hand)

678 offsuit 3:1
678 suited 5:1
777 offsuit 5:1
777 suited 20:1
5 card 21 2:1
6 card 21 3:1
7 card 21 5:1

These bonuses will add a bit of EV even when using the normal basic strategy however, to get the most out of them, there will be changes to basic strategy. You would hit 6-7, 6-8, 7-8 and 7-7 more often, even more so when suited. There would also be separate hitting strategies for 2, 3, 4, 5 and 6 cards in a hand due to the 5, 6 and 7 card 21. The changes would be similar to what is done for Spanish 21, but not exactly the same, since the tens are still in the deck. Having said that, the benefit will be small. Certainly not enough to make this a winning game using basic strategy alone.
