Lets just put the answer here so it is easy to find for future googlers.
- BCA rules are the same as the WPA rules. And in those rules a scratch on the break is ball in Kitchen (behind the headstring shooting outward). These are the same rules used by the APA, VNEA, UPA, NAPA, TAP, ACS, really everybody.
There is one single organization that has bucked that rule and tired to simplify the 8-ball rules by having ALL fouls including the break shot be Ball In Hand Anywhere. That is the BCAPL.
The Billiards Congress of America Pool League is not run by the BCA. I know right? The BCA sold the league to the company Cue Sports International. They play by all of the BCA rules, except this one. They are the only organization I know of playing by the scratch on the break is bih anywhere, but they run the US Bar Table Championship, so they have a pretty good influence on the game.
But generally, scratches on the break go to the kitchen, but by every major ruleset, this is the only time a scratch goes to the kitchen. All fouls and scratches after the break are Ball in Hand Anywhere (again, thats everybody).
- If you are playing by BCA, BCAPL, WPA, VNEA, UPA, ACS and NAPA all use the rule that if the 8-ball is on the table, the game is not over. Meaning, a simple foul or scratch while shooting at the 8-ball does not lose you the game in any of those rulesets. Easy rule to live by, if the 8-ball is still on the table, the game is not over! Now if you pocket the 8 AND foul in the same stroke, then you lose.
Only APA and TAP play by the rule that a scratch while shooting at the 8-ball is a loss, and no one in the world plays that a simple table foul (such as failure to hit the 8, hitting opponent's ball first, failure to reach a rail after contact) loses the shooter the game.
- The 4 balls to the rail rule in BCA says that the incoming player has the option to rerack, or continue shooting. Rerack is NOT compulsory.
