Illegal Pitch Award Question

[DaveASA/FED]

Cecil,
Just to make sure I am with you. If the ball is batted and all runners advance one base the IP is null and void.

so a few other situations:
1) R1 on 3rd B2 hits an IP (so signalled) and is thrown out at first R1 does not score. Does the IP get enforced?
2) Same but R1 scores, then no IP and B2 is out?
3) B2 hits the ball foul (uncaught) then IP is enforced as R1 does not advance?
4) B2 hits a long fly ball in foul territory that is caught, R1 tags up and scores, then no IP?

Am I thinking of catcher's obstruction, or does the offensive coach get an option in IP also? Or does the batter remove the IP any time they swing at it?
