One of my dear friends from the late 1990s told me a story about how she was in this tough money match and she kept missing the 6 ball.
She wasn't sure why it was going on but she just kept missing it. Out of all the balls, she missed the 6 ball the most for some reason.
Eventually she was so in tune with what was going on, she decided to play safe every time the 6 ball was next. Even if she had a straight-in shot on the 6 ball, she would play safe!
And yes, she ended up winning that big money set :)
It goes to show to be aware of what is going on with you in your matches early so you can figure out solutions to help you win. All about those tools in your toolbox. :)
