What to do, what to do?

One play I'm still uncomfortable with:

Okay, one play that I see fairly often that I'm uncomfortable with:

Rebounding A1 and B1 both go straight up close together, arms all next to each other. A1 gets the better angle and both hands on the ball, but B1 doesn't give up. A1 gets possession but also B1's arm, which is now clamped between A1's arm and A1's body, with little or none of B1's hand touching the ball. A1 is still intensely "squeezing the ball" as teammates are recommending loudly, and in the process is squeezing B1's arm. It's NOT B1's fault, she's just trying to get her arm back, but not a lot she can do. I've seen partners call holding on A1, "illegal use of hands" on B1, and nothin. I usually call nothin, but don't like it.

What to do, what to do, she fretted nervously?
