ok, i know you should stand on 16 vs. 10 when the count is positve, but it seems to me you should stand on 16 vs. 7, 8, and 9 as well, maybe "even more" so. I would think the dealer would be more likely to have a sub-17 total with these up-cards and draw to bust with a 10-rich deck even more. Is this thinking incorrect? Thanks.
