Agreed.
BuggBob wrote2) If the runner and F3 collide before the ball is bunted…Obstruction, award bases as needed. But if the collision occurred after the ball was bunted… Interference, runner is out, batter may also be out on the interference on a potential double play.
Agreed.
BuggBob wrote3) IFF for one out, DB out for INT end of the inning.
Again, depends on where it occurred, and if another fielder could have had an opportunity to make an out.
BuggBob wrote4) Could it be interference if the batter was not in the running lane?
I don't think whether or not the BR was in the running lane would affect this play, as the rule, sadly, only pertains to the BR interfering with a throw to 1B. If the BR is running normally, then I'd have no INT. If they are running in a way that puts them too far into fair territory, then I'd have INT, as it would appear that they are intentionally going out of their way to block the throw.
BuggBob wrote5) Ball on batter, no illegal pitch, runners advance with liability to be put out. R1 scores, R2 is Obsructed.

I'll just have to leave this one up to you FP guys. 🙂
