Mr. El Chapo,
As with most things, when discussing the relative merits of various strategies when approaching the game of one pocket, small things matter. Details like RELATIVE shooting abilities of the two players, as well as knowledge and moving ability matter.
We cannot say without exception that just any great ball pocketer will beat any self described mover (or older style player), can we? If that were true, just any whiz-bang nineballer could step up and immediately take over the one pocket world.
So, we recognize that a certain amout of knowledge and experience is required to play your best one pocket.
Also, one's own definitions of things like what is a tough shot or what is a good shot matter. In my own case, for example, a tough shot is one I must make (and it is probably a difficult shot), while a good shot is one I don't have to make, hanging it might be just as good, but definitely I am able to put the CB in a place where my opponent won't be happy.
Two pure shooters playing one pocket, neither one paying much attention to defense, the better shooter will win most of the time. Two pure movers playing, neither one can make a ball, the better mover will win most of the time. A not so pure shooter playing a not so pure mover, the result is going to depend on their relative offensive/defensive skills.
I would not argue that when ball pocketing skills reach a certain level, like SVB or Danny Smith for example, offensiveness seems to rule the day, but both of those guys have been beaten by lesser shooters who moved better at the time.
No one has ever accused me of being a shooter ( I have my days), but I can beat lots of better shooters if they don't have an adequate respect for the defensive side of the game. My success rate, like everyone's, depends mostly on my ability to judge how much disparity exists, and how much I can overcome. For those of us who are not great shooters, that is the real allure to one pocket.
P.S. Many a King has lost his army trying to lay siege to an impregnable fortress.
