Verbage: A8, DD on 6, "if able", OTW stand, unless,
 
H17:TC≥on 4, TC≥1 on 5, then DD, and if *RC<0 on 6, then stand.
S17:TC≥on 4, TC≥1 on 5 & 6 then DD (TC<1 stand).
Note: BSA Deviations test is wrong on this. Its says the deviation is DD TC
≥1. That's not a deviation because a deviation a deviation from basic strategy and basic strategy says to you should DD on an A8 vs 6s. The deviation would actually be to to stand if the TC<1. BSA doesn't even have that as an option. It wants you indicati DD if TC≥1. So that's the most correct answer. But once again, that's not a deviation. The H17 of A8 vs 6 correctly identifies the deviation as standing on RC<0 against a 6.
