Should any situation arise whereby a legal shot is IMPOSSIBLE to play, then the game shall be restarted by the player who started that frame, whether this situation has been arrived at by accident or design.
If in the opinion of the referee neither player is allowing the game to progress, or a stalemate situation has arisen, then the game shall be restarted by the player who started that frame. The referee shall not allow numerous visits with neither player making any attempt to make the opening pot which decides the playing groups (unless it is felt that progress is being made). If the player who started that frame did so by virtue of their opponent making a foul break, that player will break on any restart, not the opponent who made the foul break.
A referee may, only if requested, advise on the rules of the game
