I hope all of you understand, but I doubt you do, but is a B player in 9B the same as a B player in 8B and if neither have the experience of playing 14.1 do they still rate as a B player against a B player that only plays 14.1 and understands the game?
As far as high runs go, don't let yourself be fooled by a 100 ball run, playing 14.1 is only played 14 points at a time, then successfully repeating the 14 balls again and again. And, as far as that goes, an 8B player has a better chance at 14.1 than a 9B player does because pattern play and back up balls to chance the pattern play is more practiced playing 8B and is non-existent playing 9B.
