After wading through endless threads on the "ghost", I've concluded that the following are the best rules for playing the ghost...
* Rack and break from the kitchen. If the game ball is made on a legal break, you win (if allowed for in the rules of the game being played). Any scratch or foul on the break - ghost wins.
*Take ball in hand and attempt to run out. Any miss or foul - ghost wins. Optionally, if there is an open shot after the break, do not take ball in hand.
*If necessary, a safety attempt is allowed and must be intentional. If the safety leaves a direct hit on the object ball - ghost wins. If the safety is successful, take ball in hand and continue to run out.
*Standard race is to seven, but may be adjusted for more accurate results.
