The room I play in has a twelve ft. Snooker table. The table is reserved for ring games specifically but heads up golf may be played when the regulars have not arrived for the daily ring game. It is also called an OPEN table in regards to the ring game. Question is once a game begins (usually 3-4) players, doesn't really matter, can new players come into the game at any time? They of course start at the one hole. Because of tight, unforgiving pockets and the twelve ft. length, games take 3-4 hours easily. How is pulling out of game handled? What about giving up your spot to another player cause you need to leave or just want out for whatever reason? People seem to pull out when world beaters enter the game.
