Avoiding an obstructing defender

[DaveASA/FED]

I dont think anyone is argueing that if the runner goes out of there way to make contact that it would not be OBS. I at least am picturing s fielder running the runner back toward a base then throwing the ball so the runner turns around and heads back to 2nd and there is the fielder still directly in her path. Now the ?? is what does she do. I think all the answers are true, can't have malicious contact (obviously), but if you run like she isn't there and make contact (don't move where she is but run like she isn't there), or try to step sideways to avoid or step right up to the fielder and slow down for her to move......any of these will get an OBS call from me.

Irish your point is taken that the runner can't go out of his/her way to attempt to create the OBS.
