Though the differences are minor, does anyone have an opinion on the effectiveness of the KO basic strategy charts versus others. I have used KO before and enjoy it's ease and do not have time now to change over to a different count prior to my next trip to LV so...as I put the finishing touches on BS and count practice, I am plagued by questions such as; Why KO hits 2-2, 3-3 v 2 & 3 when other counts split. I initially learned Thorp's BS table and know there have been updates. I know that, based on table rules, the BS changes slightly. I am looking for the best "generalized" BS though (cheap and unchallenging, I know). I'm curious why there is any variation at all in BS tables (table rules remaining constant) from author to author.
Know this may be a drab question so, thanks in advance.
