BS for D9 but also DAS with D9

[Caruso]

Ken,

What are the splitting changes to standard six-deck D9 and limited DAS - you can double on 9, 10 & 11 after split?

I figure 66 v. 2 goes from hit to split, but not sure about others (or that one either).

EDIT: Full rules are: Six deck, S17, D9, no DAS but D9 as above after split, and also ENHC.

EDIT AGAIN: OK, having applied my miniscule cerebral faculty to the task, I'll take a guess that ordinary DAS strategy is correct, since soft doubling doesn't come into play with 22 and 33 v. 2 and 3, nor 66 v. 2.

Would like confirmation though.

The normal DAS strategy applies to this game. There are no basic strategy doubles after the marginal splits that would be prohibited by D9.

Now, I don't know the answer to this question in a D10 game.
