I. Threes Scenario 1:
B) Solution - The key is to execute a perfect stop shot to give yourself the highest odds of running out.
II Scenario 2:
Solution: Use max low left with a soft spin stroke. Dig in.
III Scenario 3:
Solution: Use high right with a big powerful long follow through. Get to the 3rd rail and leave yourself an angle on the 8 so you can get shape on the 9. If you hit it too full, you will scratch. This shot requires you to stay perfectly still and keep your cue level the whole way through the shot. Remember to look at how you cue stick looks AFTER your shot to see if it stayed on the same plane.
