Suppose this situation occurs playing bar box 9 ball:
You just broke and pocketed the 2 ball.
The one-nine combo is dead in the corner, so your opponent concedes the rack.
Now you want to re-rack using one of the extra balls (10-15) left over.
So we choose the 10 ball and will add that to the eight balls left on the table (we are playing nine ball).
Now here are the options -
A)
you use the 10 ball to replace the 2 ball (intuitive interpretation, they are both blue) keeping 9 ball as money ball
B) you make the 10 ball the money ball (literal interpreation of rotation using nine balls)
