What is the EV playing this way?

Rules:
6-Deck, dealer hits soft 17, BJ pays 3/2, split once, DAS, Double 10 and 11 only, dealer checks for blackjack.

What is the expected value using the strategy below for the game above:

Assume that I play correct basic strategy for all hands, except:

Stand on hard 12 vs 2 - 3
Stand on hard 14 - 16 vs Ace
Stand on soft 18 vs Ace

I get about -1.07% as the initial bet EV for the above deviations, when playing correct basic strategy for all the other hands, is this right?

Not sure about exact numbers, but Stand on hard 14 - 16 vs Ace is definitely the more costly deviation. Why stand against the Ace but hit against 10 or 9...etc (I assume since that's basic strategy)
As you probably know all stiff hands are equally worthless and you only win if the dealer busts. Here are the bust rates per dealer upcard. As you can see the Ace is by far the lowest since it effectively has to bust out twice. A stay on a stiff hand vs the Ace is puzzling to me.

Dealer's
Upcard Bust-Out Rate
2 35.30%
3 37.56%
4 40.28%
5 42.89%
6 42.08%
7 25.99%
8 23.86%
9 23.34%
10 21.43%
Ace 11.65%

Stand on hard 12 vs 2 - 3
Stand on hard 14 - 16 vs Ace
Stand on soft 18 vs Ace

With above exceptions, I get initial bet EV = -1.072%

How about 7,7 vs Ace ? Do you want to change the strategy from HIT to STAND ?

A 7,7 pair is worse than any other hard 14. This means you should hit more often on hard 14s.

I agree with you that the correct strategy for 7,7 vs Ace is HIT. I just asked if this particular hand should deviate from the basic strategy.

Yes, in my strategy I will stand on that hand as well. Is that hand included in the -1.072% EV that you got?

Important note: I am not promoting this as a strategy for the basic strategy player, as it will cost them about 0.2%

Update (about 950 pm, Pac Time):
I don't think the "... vs Ace" strategy deviations that I mentioned are useful for anyone***, except me .

***: Even for a card counter (though I haven't looked into it, since I don't count cards).

Actually being 7,7 LOWERS the hitting EV, since you've got two of the cards that would give you 21. (That's why for single deck basic strategy says standing on 7,7 vs. 10 is better than hitting.)
