What index should be used to late surrender 17 vs A, and to surrender 8,8 vs A for H17, 7/8? According to Professional BJ, page 261, 17 should be surrendered against A at TC +2 or lower, and 8,8 should be surrendered vs A at TC of -5 or higher. I downloaded indices from demo of CV and all were what I expected except there was no index for these two; that is, the CV demo said not to surrender. Given my lack of technology skills, I could have messed up in running CV, so I want to make sure I know the correct index. Thanks for any input.
