The advanced move is to push the two balls behind the back ball gently so there's a "chain reaction" that alters the two balls behind the one ball. This manipulates one of the two corner balls "DEAD".....it may take a couple times to get it just right, but then it's brutal.
By the way, I don't use this, but I do teach 5 different ways to look for cheating on the rack......and if a player uses them to his benefit, it's on him, I do believe in "Karma".
There's some really devastating ones using the magic rack, especially playing 10 Ball...you still have to break well, but it basically wires 3 of the 10 balls every time.
Are you talking about 9 ball?
I was talking about the last row of balls when playing one pocket. If you do not freeze the balls....it always breaks out to give your opponent a shot at his pocket instead of heading towards the short rail.
Oh, and Happy Birthday and thank you for the viewing of tips on your web site.
