Elbow Rule: A player's elbow must not cross the edge of the table during a throw; Interference: Distracting a player during their throw; Ball Retrieval: Touching opponent's cups when retrieving a ball
Why people argue about this
People often assume that an elbow violation only disallows a shot from being valid, forgetting that it also gives the offended team an extra throw. However, they frequently overlook the fact that interference penalties result in just one additional throw for the offending side, not two as some might mistakenly believe.
