I'm well aware that I will have to prove this to you and many others (ps: you're first statement is not true fyi).....I will enjoy seeing the look on your faces when you "real eyes" how complex 'Two Show Shoot Out' really is......am I saying I'm an expert at the game? Yes, I AM saying that loud and clear......I've won much more playing Two Shot Shoot Out that Efren's won playing One Pocket.
There's many things about the game that only a few players know.....those players are including ones like Reid Pierce, "Country Calvin", David Matlock, LA Keith, Omaha John, Weldon Rogers, Buddy Hall, James Christopher, Sammy Jones, Johnny Ross, etc.
I know the game inside and out because of the players listed above - as with all evolving knowledge, it's learned by "standing on each other's {information} shoulders.
One pocket is a very strategic and complex game, but it is still limited because there's only one pocket you score in and one pocket you have to guard against. In 'Two Shot Shoot Out' there's usually more balls that you can effect and there's 6 pockets you can shoot at AND you have to guard against. This brings about potentially thousands of different variables (maybe even millions according to Einstein

) .....I'm not sure how to calculate the number, so I'm making an educated guess.
Those that have "eyes that can see" the deepest levels of pool will start to understand the differences with those hints I just offered.......although it takes many years to actually learn the shots and scenarios.
