Hi all,

Can anyone with the CVCX program run the following rules into a sim to give me house/player edge and strategy card?
6 Decks
Late Surrender
DAS
No re splits
Double on any two cards.
Double Down rescue
S17
Dealer Peeks For BJ

Thanks in advance.

Without Double Down Rescue, but with all the other rules, I believe the player EV = -0.3864%.

I think the only time that Double Down Rescue comes into play for basic strategy is when you double a 10 vs 8 or 9 and make a stiff hand: H12 - H16. Standing on a stiff hand vs 9 is -54.35% to -54.50% (depending upon your cards) ; standing on a stiff hand vs89 is -51.2% to -51.4%. So Double Down rescue is preferred in those situations. I'm too busy right now to figure out the Double Down Rescue impact on house edge.
So many better men, a few of them friends, are dead. And a thousand thousand slimy things live on, and so do I.

I don't have CVCX, but the infinite-deck model finds that adding double down rescue to your other rules decreases the house edge by 0.00103 (0.103%.)


You would rescue any double down vs 8, 9, 10, or A that resulted in a total less than 17.


The only strategy changes with your rules: double down 10 and 11 vs ace

I’m surprised that when you double vs a dealer ace, and end up with 17, that it should not be rescued.

Since the dealer only busts with an ace 11% of the time

Edit: After the dealer has peeked at the down card, standing on a hard 17 vs an ace is about -47.1%, which is better than the -50% of the Double Down Rescue.

After the dealer has peeked and you know that the down card is not a Ten, the dealer ace will bust about 16.9% of the time.

Thank you for the help everyone.

I don't know why, but I was assuming there would be other basic strategy deviations in the case of some hands like 9v2, 9v7, A6v2, etc...

Regarding other doubling decisions such as doubling 8 or 9 or soft hands: you would only double those hands vs dealer upcards 2-7, and versus those upcards you would NOT Double Down Rescue, since it is more favorable to stand. Thus, you should simply refer to basic strategy for making those Double/Hit decisions.
