Rail first to score
The 9-ball is hanging on the lip. If you decide to try to make if off the 1-ball, the best bet is hit the rail first with left sidespin. The same is true from the other cue ball if the 2-ball is the lowest ball on the table. Try these patterns and I think you’ll agree that they are better choices than anything involving ball-first hits. With more balls on the table, the same patterns might be good for safety plays.
