I don't know about that??? I'm not one to sit through an "artistic" pool match...it's boring... decent player, practice a handful of "trick" shot's from the EXACT position ad infinitum... Props all over the place. It's a circus.
Alot like golf... no two shot's are exactly the same, then factor in position for your next stroke. U don't worry position in "trick shot" pool do ya? You can "learn" some stuff from it, but I'd 100% rather watch or play "real" billiards.
The most important ball on the table--(pick a game), is colored white...preferably with measles.
I do not disagree with you either, however if you would have watched me go at a table in my early 20's with a show of nothing, but masse... Ask anyone that ever saw me on a good day (one I wasn't losing my temper). It was pure...No wax, no pool sticks on the table, no racks, no second ball in the corner to make it a combo. Nothing but a 19 oz. playing cue, and the white ball. I love your post, but please do not knock all types of tricks. There are some that really are crazy hard even after you have mastered them. Putting the cue ball where you want is done in golf too.
The tee off, and any shot that is out of bounds, or too hard? Yes, there are even some tricks that take shapes...Not many, but it is possible to shoot 30 different shots on a table without touching any other balls, and without moving the white ball...I had the honor of seeing Bill Marshall do this years ago...He made 30 different 3 ball set up shots (They are all set up on the table when he starts, and he only lost the cue ball one time, quite the show of skill I think...This is one of the only times I saw tricks going in, and was amazed.
It is however a pure sport and one of the oldest parts of our game...It is one of the purest parts for another reason too. A very common motive behind shooting trick shots is to make pool seem like fun for people that do not play...This is a pure motive imo. A little more pure than trying to take all the money out of their wallets.
