This is my sixteenth article based on the "The Video Encyclopedia of Pool Shots (VEPS)," an
instructional DVD series I recently created with past BD columnist and good friend Tom Ross.
VEPS contains 750 shot types and principles within 50 main categories and 5 major areas. An
outline of the entire VEPS series and video excerpts from each DVD can be viewed online at: dr-
dave-billiards.com/veps. Last month, we looked at jump shot physics and technique advice,
which is covered on the fifth DVD: "VEPS V ≠ Skill and Specialty Shots." This month, we'll focus
on massť shot technique and examples, also covered on the last DVD.
A massť shot is one where you hit down on the cue ball (CB) off center to curve the CB's
path, usually in dramatic fashion. In the early 1800's, a brilliant physicist and mathematician
came up with a remarkably simple way to predict the direction of the CB after curving ceases and
natural roll begins. His name was Gustave Coriolis, the same guy who discovered the "Coriolis"
