Use follow, leave whitey on the head rail.
Bank the 9 ball with speed 3 rails long past the side, and open up the 8/13. If it banks longer, it'll then move the lower balls towards my hole, I might even get a carom or combo and make a ball or hang it.
Another option he has would be to cross the 9ball to the top left pocket sending the cue ball toward the side pocket near the rail. From that position he puts the 9ball in play, protects the position from an up-table game, and pretty much forces Gabe to play off the 14ball.I like Jerry's shot two railing the 14ball. This shot is all cue ball positioning it in back of the 9ball. The two rail bank plays short which is ok as long as you use the 9ball as a blocker. Four railing the 9ball is a tough shot to control the cue ball which is paramount considering the position of the 4ball which is ideally positioned to pocket the 4ball and take out the 12ball.
