Thanks ksdjdj for your input.

You are spot-on regarding the House-edge.

House edge by Stephen How Consulting: DOUBLE ON ANY NUMBER OF CARDS (any Soft/Hard 9, 10 or 11 Only) H17.
6-Decks 1.9417%.

For those that are interested, I will update the strategy here some time next week.

Strategy for Top-Up Blackjack:



This is just the strategy for when the contrast wager is still "in play", right?

Also, this strategy must be for a different version of the game, as the player can only double on soft/hard totals of 9-11, right?

There is also at least one*** change to this strategy if the contrast wager had "automatically lost" , you should double a Soft 20 against a 7, yes?

***: haven't checked any others, but doubling a soft 20 (a+9) against a 7 is worth an extra 0.11+ in EV , when compared to the players' initial "main bet" (again, only for when the contrast wager had already lost).

On hands that can have two "best plays", maybe there should be a basic strategy table, that has two choices side by side, where the left choice is for when the contrast wager is still in play, and right choice is for when the contrast wager had already lost (see example below).

For example: for a soft 20 vs 7, it could read "S/D" where "S" is when the contrast wager is still in play, and "D" is for when the contrast wager had already lost.

Note: I used 6-deck and dealer stands on 17, for figuring the "EV improvement" for all of the above.

Update ( about 454pm)

If my calculations are correct, you should also double a soft 19 (A+8) against a 7^^ or 8** (when the contrast wager had already lost)

^^: It is worth an extra 0.2+ in EV compared to the initial "Main bet" against a 7

**: It is worth an extra 0.09+ in EV compared to the initial "Main bet" against an 8.

------
Update 2 (about 508pm)


If the player pushes with dealer on doubles (or splits) then my understanding is that he will profit 50% of his initial bet on that hand.
So, the estimated EV improvement figures I gave will probably be a bit lower than the real improvement figures (since mine did not include the chance of a push with the dealer).

Thanks ksdjdj,

Below is also come with the report (I for got to put it up).
Yes, you are right. This strategy is for a different version of the gameIt (is based on a 6-deck shoe game with Rule Set-I) see below.

BTW. Hi Ksdjdj,
Thanks for taking your time on Top-Up Blackjack.

Here is a link to the Report for Top-Up Blackjack (AKA, Contrast Free-Match 21). http://bit.ly/2X4hv4R
