This is the best description of the phenomenon so far.Rod said:It hits the point with topspin, clears the other side point, then top spin makes it hug the rail on the way to the pocket. As mentioned above, it is a rolling ball at speed. How many of these have you seen at slow speed? My guess is probably never.
This is exactly what happened in the 2004 Challenge of Champions semi-final match between Thorsten and Mika. Thorsten had a tight angle to pocket the 3 in the side. He hit the near point, and the ball swerved a bit and rolled down the rail to the far corner pocket. Everything was going right for Thorsten in that match, and nothing was going right for Mika.
I don't think it's possible to hit the far point of the side pocket and have the OB run down the opposite rail to the left corner pocket. For this case, the point would cause a much greater change in OB direction, and I would figure that all of the top spin will probably be absorbed by the point at impact. I could be wrong, but I've never seen that particular case.
