Bunt/chop in SP

[greymule]

We all know that bunting is illegal in slow pitch. A batter who bunts a pitch is out. In a recent business league game, I called a batter out for bunting (though he made a comical attempt to fake a full swing by continuing to move the bat around after the bunt).

But if the bunted ball is foul, is the batter still out? Or do the words "within the infield" imply that to be considered a bunt, a ball must be fair?

And suppose a batter bunts and the runner on 1B runs. F2 catches the bunt in the air and throws to 1B to get the runner for leaving before the catch. Do we allow the double play or call the batter out and return the runner to 1B?

I assume that a bunt attempt that misses is not considered a bunt but would still be a strike. And that a bunt foul on strike 3 would be an out.

Same with a chop. Suppose a batter obviously chops down on a ball but fouls it or even misses it? Is he out?
