This is the first article in a series on pool rules. Recently, fellow BD columnist Bob Jewett
and I spent a weekend filming hundreds of shots, with both regular and high-speed video
cameras, for a rules quiz. I also created some instructional videos and posted them online along
with the quiz. Bob has been very active over the years serving on rules committees, playing a
lead role as a rules author, and training referees. The purpose of the quiz and other online
videos is to help people (players and referees) evaluate and improve their level of understanding
of the official rules of pool, and to get better at applying the rules in various game situations.
NV B.61 contains the rules quiz video. The quiz consists of 100 different shots. Your job is
to judge each shot as "fair" or "foul." There are slight differences in rules from one league and
tournament to the next, but most rule sets follow fairly closely the official and internationally-
recognized World Standardized Rules published by the World Pool-Billiards Association (WPA).
