Jeremy Jones and Scott Frost talked about this during one of the matches. JJ said it usually didn't make sense to think more than three balls ahead because "so much could change." Frost seemed to agree.the main thing they do which most cant, is think ahead more balls. this way they are playing position to set up for the balls the weak players aren't even looking at yet.
I was a little surprised. I figure pros look at the entire table and probably figure out a total plan if the table looks easy. If not, perhaps they approach it like JJ suggested.
