I was wrong about the four red balls sin the rack. Found out today, after talking with bro-in-law, and we used three reds. 6, two reds side by side and one in the center. The object on the break is to pull of a snooker behind the 2, 3, 4 ball.
He doesn't remember where, but it had to be in some old pool hall years ago they played this. He is 84, lol, so he has played that way for a long time. Still a great shooter.
