Katarina,
Looking at BS for S17 8D game, 17 v A is Surrender.
The index is -3 and is listed as H/S.
Does that mean Surrender is for a BS player only and if counting, it's either Hit or Stand only?

Also, I'd like to keep the 8D S17 strategy relatively simple, at least for starters. I plan on using the I18 + 3 Surrender indices. How important are the composition-dependent plays to EV? Is it reasonable to ignore the 4, 5, and 6 card deviations?

Thanks.
