I'm from Philly where the game is played on a regular basis. The rules we play by are quite different from the World Championship that Mike won.
1. No shot is called.
2. If 9 goes in a player's pocket on break, the pocket owner wins, regardless of who broke. (If in a handicapped game, like 1 front to 1 back, the players may wish to spot the 9 if it goes in, since it is much more likely to go in a front pocket than a back pocket). If 9 goes in a neutral pocket on break, it spots, and breaker continues to shoot, even if another ball was not pocketed on the break.
3. If you pocket the 9 in a neutral pocket during the game AND on a good HIT, it spots up on the spot and it is the other player's shot. ONLY if you make another ball on the same stroke do you continue shooting. If you pocketed the 9 on a bad hit, (in a neutral pocket) it is up to the opponent to spot it or put it back where it was.
4. 3 fouls is a loss of game (this seems to happen much more often playing this than regular 9 ball)
5. If the 9 is pocketed in a players hole by opponent, the hole owner wins. PERIOD. Does not matter if it went in on a push, bad hit, or scratch. (some people play this part slightly diffenttly, and spot the 9 if it was a good HIT, but then a cue ball scratch).
6. Push out allowed immediatley after break.
7. If 9 is moved on pushout, opponent has option to leave it where it lay, or move it back to original position. Opponent also has option to accept or return shot, like regular 9 ball.
8. If 9 is moved on a BAD HIT, opponent has option to leave it or move it back to where it was. Note, bad hit is different than scratch. If you make a good hit, but then scratch with the cue ball or fail to hit a rail, the 9 stays where it is (of course its ball in hand for opponent though). Reread rule 5 regarding pocketing the 9 on a bad hit.
9. You can play any combo you want, including on the 9, as long as you hit the lowest ball on the table first.
10. Its good strategy in this game to try to move the 9 towards your hole any time that you can (on a legal hit of course). Unless you are a runout player and know you can get all the way out to your hole from where the 9 currently lays. For most of us that have many innings per game, having the 9 near your hole will be much more important than trying to run out early in the game. By the same token you want to remove the 9 near your opponents hole during the game, by combo, carom, etc. Don't leave it there and then try to run out, unless you KNOW you can get out and then bank the 9 in your hole or to an advantageous position.
11. Pay attention to the vocabulary I used regarding fouls. THere is bad hit, and scratch, and other fouls like not hitting a rail. In 9 ball they are the same penalty of BIH. But in this game, they are again all BIH, but what happens to the 9 ball is different. Reread the above with this vocabulary in mind.
