BJ House Edge in various conditions

[James989]

No, in that case, we would be talking about American rules. "Peek" or "no peek" has nothing to do with the house edge.
So let's go back to the previous rules where the player doesn't lose everything against a dealer's blackjack.
Using CVDATA, I get 0.609%, so something must be wrong with the basic strategy or with some setting of the rules.

I agree with you that if player doesn't lose everything against a dealer's blackjack, HE = 0.609.

I also ran simulations with CVDATA, Flat Bet, Hi-Opt 2 Counting Strategy (Full Index), HE = -0.588%, which I believe is incorrect.


Can you/anyone here use CVDATA to verify my results? Please note that the rule is Peek on Ace( No Peek on Ten !), so you should modify the playing strategy index of all BJ hand vs T.

8D,S17,DOA,NDAS,SPA1,SPL1,NS and ENHC

1) TD-EV = -0.7177% (HE = +0.7177%)
2) CD-EV = -0.7164% (HE = +0.7164%)
3) OP-EV = -0.7155% (HE = +0.7155%)

It's a "disguised" game... Dealer takes a hole card, act as an American dealer would do when an Ace is showing but tweak it in an ENHC game with any other up card.

Exactly

That's strange. Unless the "peek" is done AFTER the entire round has been played.

Dealer Ace up, instant peek and then round or no round of play (American game)
Dealer 10 up, every player should switch to ENHC mode.

Peek(American Game), HE = 0.609

Peek on Ten(No Peek on Ace), HE = 0.617
ENHC(No Peek), HE = 0.718

TD-HE = 0.6968% (instant peek on Ace but NO on Ten)

10 billions CVDATA sims results(Peek on Ace but NO on Ten) :-

HE(1 round/shoe, no cut card effect) = 0.697%
HE(cut card effect, 50% penetration) = 0.713%
HE(cut card effect, 50% penetration, Hi-Opt 2 full index, Flat Bet) = 0.668%
HE(cut card effect, 50% penetration, Hi-Opt 2 full index, 1-15 spread) = 0.013%.

The cut card effect is about 0.016. I found that no of deck will affect the cut card effect, penetration totally not affect the cut card effect, true ??

BTW, could you please sim this game with your CAC2 Enhanced counting system(50% penetration, Flat Bet) ? Just want to have a comparison.

With CAC2 + 52 indices, 50% pen, CCE, peek on ACE but not on TEN, I obtained a House Edge (HE) of 0.583%. Then, given that against a ten, everything
is lost if the dealer gets BJ, I removed the doubling indices vs. T and splitting indices vs. T (88vT). With those changes, the HE was 0.668%.

Hope this helps.

You mentioned that "With CAC2 + 52 indices, 50% pen, CCE, peek on ACE but not on TEN, I obtained a House Edge (HE) of 0.583%."

Is your CAC2 indices(for hands against TEN) that used in above simulation still the original indices for full PEEK game ? Or you have re-generated new indices(NO peek on TEN) for hands against TEN and used in above sim ? Your CAC2 looks like a strong system.

For example :-


Full Peek, 11 vs T, the indice is -6
Peek on Ace but no peek on Ten, 11 vs T, the indice is +5(re-generated).


So you used index + 5 in above sim ?

The 0.583% house advantage corresponds to a "full peek" game with American rules. In the other case (0.668%),
and only when the dealer has a ten, I used the basic strategy of a European game, which consists of "not doubling down and not splitting 8s".
For a third option, I used the European index for 11vT, which for CAC2 is +4 instead of -7. In this case, I obtained a house advantage of 0.663%.

Hope this helps.

Thank you very much !

Next task is to use the perfect strategy to simulate. I think this will be difficult.
