the swim move vs good offense

Thanks. I wasn't refferring to a dribbler but a post player. Example-A1 takes position under the hoop and holds up arm elbow bent to protect position/keep D away. B1 tries to stop incoming pass but is prevented by A1's elbow in B1's side. A1 does not extend arm, or push/displace, just matches the force being pushed by B1 to protect position. Legal in HS?

It's technically illegal in Fed, but a lot of refs don't call it as long as there's no movement at all. If the upper arm (shoot, cant remember the name of the bone!) is parallel to the floor, so that the lower arm (radius and ulna) are clear out away from the body, I think it should be called. But a lot of folks won't unless the arm moves.
