I have worked hard for a long time on my game and feel I am a pretty good player. Here lately for some reason I have started miscuing while shooting high English on the cue ball. At one time I only did it while bridging on the rail, but now I do it out in the middle of the table. Last night at league I did it three times in one game, once the cue stick rode up over the top of the cue ball and stopped the cue ball. Am I raising up or what, has anyone else had or seen this affliction before, and can you please suggest a cure.
