Here is a situation in which you might want to play a push out even with ball in hand.
The one ball is frozen to the rail very close to a corner pocket. The seven is frozen to the one ball and angled so that there may barely be enough room to pocket the one ball legally. That is, freeze the cue ball to the one ball and the cushion, freeze the seven to both balls and then remove the cue ball.
The two ball is at the other end of the table.
From past history, you don't trust the TD to make the right call.
There is no good way to place the cue ball in the pocket to hit the open part of the one ball.
I claim that the best shot in this position is to call a push out, shoot the one in (perhaps hitting the seven first, but who cares?) and leave a tough shot on the two.
