Here's a good explanation of how to make the wing ball in 9-ball. Basically, the wing ball caroms off the ball below it. But when racked, it's dead to several inches above the corner pocket. So to make it, you shoot from the side, transferring most of the energy to a chain of balls frozen to that carom ball below the wing ball, moving it slightly down table before the wing ball caroms off of it, into the corner.
The irony is that to make the shot, you just have to make sure certain chains of balls are frozen. And frozen is what the rack should be anyway, ideally. It's why making the wing ball has increased with the use of the Magic Rack.
So how is that cheating the rack? Some techniques require creating little gaps, which is gaffing the rack and therefore cheating. But making sure balls are frozen? Bah. You're not a rack mechanic if you want the balls frozen. Every bar league player tries to freeze the balls to each other in the rack - it's just the definition of a good rack.
It takes about 30 seconds to understand this, and yet Johnny Archer, probably the most experienced pool professional active today, claims he doesn't understand it? Come on. If what he says is true then he's just being too stubborn to try to learn it. And to complain that others do understand it and so are basically cheaters is ridiculous. Does he complain about people who understand hitting the right side of a frozen ball combo, or spin transfer on bank shots, or a hundred other pieces of info about pool shots, and he's too proud to learn those things?
Fine, require three balls past the head string or the center to add some unpredictability to the other balls, or move the 9 to the spot or require breaking from the center to try to prevent the wing ball from going in at all. But it's not cheating to try to understand the rack and get the balls frozen. It's just willful ignorance not to want to understand it.
