The mental side is more than just playing under pressure, but pressure usually brings out someones weaknesses....the mental side has a lot to do with self confidence and understanding the basic elements and foundation of CONSISTENCY.....consistency is the ability to do something over and over, every day, in every way....I am a firm advocate of understanding first how your feet position (the pool shot/body foundation) aligns to the shot on the table.....My new DVD goes into great detail about how to CONNECT your feet, hips, shoulders, hands, AND eyes TO YOUR CUE.....the cue MUST be more than just a "delivery system for the tip".....it must act as a measuring device (for consistent eye perception), alignment tool (for your body), and give kinesthetic (sense of feel) feedback to you hands....if you don't know how this works, then chances are you do it differently from one day to the next.....this means you are playing a slightly different game everyday, and constancy is sure to be a problem.....ESPECIALLY under pressure.....then it's VERY TEMPTING to right it all off as as "MENTAL", when the core issue is most likely physical.....that's why at times we need to be evaluated by someone that truly knows the the essential elements of the pre-shot routine and can explain the body/cue relationship. www.cjwiley.com
