Hi,

Is there any forum member who has played Double Up Blackjack recently? I ask because beyond the differences in the rules that I see on different sites, some are very misleading.
I don't doubt Michael Shackleford's analysis, who says that the house edge is approximately 0.32%. However, there are other sites that mention 0.62%, and others that say the edge
is between 0.20% and 0.40%. Let's look at one of the main rules for which I would need some confirmation:

End 16: Any Dealer 16 ends the game; pushes against all but 21.
Blackjack Pays: 3 to 2 (1:1 against Dealer 16).

Under these conditions, my simulator tells me that the house edge is 0.71%. But if instead of "1:1 against Dealer 16" it were "3:2 against Dealer 16",
the house edge would be approximately 0.38%. I want to emphasize this rule because that subtle difference would make the game less wonderful
and attractive than its creators promote.
Of course, I might be making an error in my analysis, which is why I'm reaching out to other forum members to verify this.
Thank you in advance.

Sincerely,
Cac
