Game: SD, S17, D8, DAS.

1). 77 vs. 10--- Basic Strategy, stand. K-O 14(not 77) vs. 10, +6. Should we stand 77 vs. 10, no matter what the count is, or use the index +6?

2). A7 vs. 3,4,5,6.--- B. S., double. But I think if you double and get the cards A,2 or 3, they could count on your hands 9,10,11 instead of 19,20,21. So I do not double on those hands. Should we double them if the count is high?

3). 44 vs. 4,5,6---B. S., split. Should we split those hands, even though we can only D8?

4). 88 vs. 10--- B. S., You should split this hand. But if the count is very high (+4 or above), do we stand it? If the count is negative, do we split or hit it?

Thank you in advance for your time and help.
