So wait, he did a double hit and foul on purpose, to leave his opponent on a bad spot, as a result he owed a ball and gave his opponent a point as well? This is cause to end the game, do I understand this correctly? Very interesting how people deal with this outside of tournament play.
6.6 Intentional fouls are an accepted part of One Pocket tactics as long as they are played by use of a legal stroke, such as by lightly touching the cue ball with the cue tip; by rolling the cue ball to a new location without regard for legal contact with either an object ball or a cushion; by pocket scratching the cue ball; or by using a legal jump technique to force the cue ball off the table.
However, if the acting official rules that a player has used an illegal technique to direct the cue ball or any object balls to a more desirable location, then the incoming player has the option of either playing the balls where they lie, or requesting the official to restore all such moved balls to their location prior to the illegal maneuver. The offending player is charged the standard one ball foul penalty, and in addition may be further penalized at the discretion of the acting official under the general rules of unsportsmanlike conduct.
