Using OBR, when a pitcher is engaged with the rubber and has taken his signs, before he comes to a set, what are the things that will trigger you to call a balk? Some are obvious (i.e. he drops the ball) but what about shoulder turns looking back at first while he is still down and is holding the ball at his side or back in full view.

What confuses me is the FED interpretation that turning the shoulders before coming set is a balk. I am now going to be doing league games that are based on OBR and don't want to get all messed up.

I'm a new member here. Hopefully this isn't too 'dumb' of a question. I just want to have some generally accepted criteria that will help me make the right call.

Thanks for your help.
