Just because you don't jump,doesn't mean it ain't happenen!All the above comments are 100% correct.
I big thing for me along with "3andstop's" & "DogsPlayingPool" comments, which go into detail & are 100% correct.
To recognize patterns as they lay out on the table & being able to bump balls to areas to set up break shots or key ball situations. Also, breaking out clusters and Defense, which is so important.
In 8-ball, 9-ball & 10-ball. I find it so easy to recognize these patterns. 8-ball is a lot like 14.1 That is why I like 8-ball second best to 14.1 Many times in all 3 of those games. I see players with ball in hand and they are afraid to set up a break shot on a cluster b/c they are so unsure on how to go into the cluster. Also, they often will take incorrect patterns which leads to getting in trouble few shots down the road and they will lose a game that there is no doubt they should of won. In 14.1 you learn all of these points.
The only thing that is different about those 3 games is: Jumping balls.
To be a good 9-ball & 10-ball player. You must learn & learn to do it well,
how to Jump. It does come up in 8-ball too. In 14.1 you do not see Jumping.
I am more aware of the rules,patterns,and my own comfort level with
regards to shots-shape.
