In lesson 16 in the BJ school it says for 8,8 vs. 10, you should stand instead of HIT when the TC is 8 or higher. Shouldn't it be stand instead of SPLIT?
I think you misunderstood. The whole table is about whether or not to split. In this case it made a comment that you should stand, as opposed in every other split or not situation where you should hit.
Also, in the same lesson, 9,9 vs. 7 "split at ". What is the correct number?
You're right, it is missing the index number. According to Professional BJ, the index is 3.
