A shot aimed so that the center of the cue ball is in line with the edge of the object ball , eclipsing half of the ball. "Hit it just a little thinner than half-ball." Assuming a cling does not occur, the shot will impart post-contact momentum on the object ball in a direction 30 off the direction of the cue -ball's pre-contact momentum. Also notable because the carom angle the cue ball takes is more consistent than at other contact points.
