I read Nick Varner's article (August 2018 Billiards Digest) about Johnny Archer telling him that most of his misses were due to mishitting the cue ball. Now if one of the greatest players in the history of the game makes that statement, you can be assured it applies to us that play this great game on a much lower level than he. So I decided to test my stroke with the usual methods that have been used for decades by all of the instructors out there. What I discovered was that what appears to me to be center cb, is in actuality not true center. Now I should mention that I am a senior with not 20-20, wear glasses to read, (but not to shoot) and have had some eye issues in the past. But I digress. Having said all that, I find that I consistently cue so very slightly to the left of center. When I purposely adjust my tip to what "appears" to me to be slightly right of center, it is in actuality right on center. So my question is this. Should I try to find a different stance, head position, bridge or whatever else is causing this illusion, or should I just keep my stance, head position, etc. and just cue to the slight right of center, (for my eyes) and be pretty confident that I will be at center cue ball. I play at a 5 level in the APA and feel that I could be much higher if I could eliminate some routine shots that I have been missing.
