IIRC
16 v 9 is a basic strategy surrender, as is 16 v T. Hit at -1 and -3 respectively.
15 v T has an index of 0. 16 v A is a basic strategy surrender.
14 v T is a surrender at +3 or higher.
Wrong on several things. If surrender is not possible, the index to hit 16v9 is TC 4 and less and for 16v10 it's -1 and less. You stand on 16v9 at 5 or higher and stand on 16v10 at 0 and higher.
For 15v10, if surrender is not available, you hit at +3 and lower and stand at +4 or higher. For 16vA, if surrender is not available, you hit at +2 and lower and stand at +3 or higher in a H17 GAME. For a S17 game, if surrender is not available, you hit at +7 or lower and stand at +8 or higher.
This is for Halves, but very similar to HiLo since HiLo and Halves have basically identical indices or have about a '1'point difference in the index.
