There needs to be a definitive glossary of worldwide official definitions of pool terms
I too have been caught in a snare of exact pool terminology here. I repeat some term used by a world class instructor and someone challenges the exact meaning.
As far as pattern play being expressly limited to ball selection, there are MANY professional instructions who teach pattern play for nine ball. Bob Jewett has a nice video on Dr. Dave's VEPPS cds entitled pattern play for 9 ball. Tor Lowry has a new 3 cd set about pattern play and he alternates between 8 ball and 9 ball.
Deciding which ball to hit in which order is only one component of a pattern. Planning out an entire rack of 9 ball and visually creating a road map of what you intend to do based on the skill set you have and the likelihood of success is a pattern. It may not be a pattern according to a specific definition as established in some nationally accepted dictionary of terms (oh that one actually existed for pool) but it is a pattern.
If you decide to hit the one ball in the side so you can easily get position to hit the 2 ball in the corner so you can use the 3 for a breakout ball for the 5 and so forth, that is a pattern. It is a different pattern than if you decide to shoot the one ball int the corner and do something completely different, even though the sequence of balls is the same. The pattern is completely different. Position is getting the cue ball where it needs to be to complete the pattern. To me the pattern is just that, a pattern. It is the strategic level. Position is the tactical level.
But that is just how I see it. Others may differ and they can easily be more correct than me. I am more interested in the concepts than the definitions. I also hate to see all the conflict here. This forum is a place for me to communicate with others and share ideas. I hate to see all the dissension. I think it is mostly a weakness of text vs. verbal communication. With text there is no way to interpret the inflection intended with a comment and it is easy to read too much into things.
As for me, I like and appreciate everyone who contributes and have no axe to grind with anyone. It is perfectly OK to disagree with me about anything.
It is even ok for me to be wrong about all my ideas. My wife would certainly agree with that.:wink:
