At
times the balls will fall in such a way as to create a 'wide'
or 'big'
pocket.
This occurs when a ball settles close to a pocket, allowing
an object ball to be potted into the same pocket by cannoning
off the ball that has settled near to the pocket rim.
A
ball close to the pocket increases the margins available
for making the shot, as one ball assists the others path
into the pocket.
Often in circumstances such as these, the first ball enters
the pocket without contacting the supporting ball. Although
the second ball was available as back-up it is not required
and remains available for the remainder of the visit.
Keep your eyes open for these openings, as they often present
the opportunity to make a successful pot when in different
circumstances you may not consider going for the shot.
