I think all the crazy banks on the 13 are just that -- crazy.
If someone really wants to win from here, the best chance I see is getting the other player to take an intentional scratch (or forced) by titty hooking him.
He may play an intentional foul back to put you in the same position, or he may try to kick the ball in and miss (understandable when titty hooked without a stable bridge, etc.) and fouls.
That way, he at least needs two when you make his 3-ball and follow the rock in. The 3-ball comes up with one of yours, and it's a better situation than before.
Unfortunately if you're playing a good player then he should still be able to play the 13 but by this point there are 3+ balls now on the spot and a bank is tough.
I'd say someone's chances from here are less than 1:100, but there's what I think about how to win from there.
Oh, and if anyone's watched the 200(2?) DCC match between Parica and Joyner, Parica is in this exact same situation. His answer?
Parica makes Joyner's hanger at warp speed, I assume hoping to hit the (in this case) 13 and either scratch or pop the ball off the table. Needless to say, he doesn't and loses.
