I think Jake Schaefer Jr made 39 consecutive 3-cushion shots on two balls near a corner by reversing the corner. It was a set-up position and not achieved by position play. (needs fact checking)If you could master short rail doubling the rail banks on a small table, then you could keep both balls in the corner for a few “small” points, and then three rail bank or three rail with a thin cut to reposition the balls. I’ve seen this pattern a few times in the 9 foot table but way hard to control. Maybe it is possible on tiny tables.
