I’ve been playing pool since 1961. There were no ‘aiming techniques’. I started reading about them online on the Billiard Digest site. Hal was one of the contributors and explained fractional aiming breaking down the object ball into fractions (1/2, 1/4 and 3/4). But instead of breaking down the object ball I began to breakdown the cue ball when aiming. It works and is just as well if not better than breaking down the object ball.
