2D Basic Strategy

[BugsySeagull]

I discovered that I've been playing double deck wrong! There are a few parts of the 2D, DAS game that I've been getting wrong, according to the basic strategy generator on blackjackinfo.com. Here are the decisions I just discovered I was supposed to do:

4,4 vs. 5 = split
4,4 vs. 6 = split
6,6 vs. 7 = split
7,7 vs. 8 = split
A,7 vs. 2 = double

The pair of fours decision I've known to do in 6 deck games, but for some reason I thought it was a hit in double deck. But the 6,6 and the 7,7 decision really baffle me! I ran simulations on BJ PowerSim to see what difference it would make to follow or to not follow these decisions, and it didn't make much of a difference at all. Are these correct?

You didn't specify H17 or S17. Doubling A,7 v. 2 is correct for the former but not for the latter.

Sorry, it's H17. But everything else is good??

[DSchles]

Yes, they're all correct. If you find it on bjinfo.com, it's right.

Well, there it is. But according to the sims I´ve run, there isn´t much of a difference between using these decisions or not. Perhaps going back and forth between splitting and not in these situations could be good cover?

6/6 vs7 split? 7/7 vs 8 split????

Why the question marks? Why do we DISCUSS BS? It is what it is. You either know it or you don't know it. What you don't do is QUESTION it. This isn't the 1950s, for crying out loud!

In general, any play where the strategy depends on the number of decks or S17/H17 is going to be a close play either way. With the splits in particular, those hands just don't come up that often. Making the wrong play isn't going to show up much in your overall results (low frequency times low difference in edge equals not much effect). But, right is right, and making the wrong play does have a real cost. So make the right play. But that's why you aren't seeing much difference in your sims.

You missed a couple more.
9 v 2
11 v A

[BugsySeagull]

You missed a couple more.
9 v 2
11 v A

OK, add one more mistake to the list. I need to double 9 vs. 2! At least I've been doubling 11 v. A though lol

[stopgambling]

I know why I am confused by 6/6 vs 7 ,and 7/7 vs 8 is a split ,because I read dd strategy which is a bit risk averse.

How about doubling A3 v 4? It's another big money maker.
