I have been thinking about this a lot. I am sure everyone can relate to the sour feeling of missing a ball that should not have been missed at one time or another, especially when the pressure is on. Sometimes you miss when you are in the flow of things just playing on autopilot (which is typical in a straight pool run). I have come up with some explanations which I feel are the most important ones:
1. Tunnel vision/loss of focus. Under pressure trying to maintain focus and remaining calm seems to take up a lot of the energy and focus that would be used for analysis and psr in more normal situations. We fail to see more viable options and skip portions of the pre shot routine.
2. Tensing up: Under heavy pressure certain aspects of touch are lost due to tensing up of joints and muscles. Stiffness in the biceps forearm muscles seems to limit the free pendulum movement and throws the elbow into the shot. This is further accentuated by tensing up of the hand, which amplifies the effects of the unwanted movement in the elbow. This is may be the main enemy that I am fighting right now.
3. Rushing. When in the flow of running balls it is easy to sort of glide sideways into the next shot instead of stepping in. This works fine for a couple of shots usually, but slight errors tends to compound especially in straight pool and may cause a miss. It is a tricky thing because in order to run a lot of balls in straight pool you need flow and the pace usually speeds up because of it. This effect can both give you higher runs and can also kill high runs.
4. Rushing part two: By rushing into the shot we fail to observe the angle properly while standing up, thereby misjudging it.
5. Moving during the shot. Same reasons as 1.
6. Major adjustments to aim while down on the ball. Rookie mistake commonly made by even great players. Often because of rushing.
7. Having generally unsound fundamentals. At one point in a players development this may be the main cause of misses.
8. Equipment. Having a sticky shaft, bad tip, hasty chalking etc. Again, rushing seems to be the cause.
Do you agree with my list? What do you think would be the greatest method(s) to combat these problems?
