Catcher's Interference or Obstruction?

[mbyron]

Ozzy and Tim have it correct: pro instruction (which also applies to the FED rule, which is substantially the same - only the name is different) is to call the violation when you see it and allow play to continue.

If BR and all runners advance at least one base, disregard the interference (why would the coach take it anyway?).

If the BR is put out or any runner fails to advance, then enforce the interference:
BR gets 1B,
R3 (if any) who was stealing/squeezing gets HP,
other runners stealing get their advance base,
runners forced move up,
any other runners not forced and not stealing remain at their TOI base.

O-coach can stop me to ask/discuss/request to keep the play. I will NOT approach him. The rule specifically requires him to ask me immediately at the conclusion of the play (umpire discretion as to what "immediately" means, and it's probably level-relative).
