I saw the clip, didn't see a foul called on the initial play, but it's hard to know. It looks as though their arms just got tangled, but then white got impatient and shoved black. It was silly of black to retaliate, since she was in no way inconvenienced by the play. I mean, the ball didn't come in, and she got right back into position. Just goes to show that women can be equal to men in hot-headedness.
