The aim of the game
The aim of the game
Certain principles come into play here. Number one is he needs 2 balls to win and you cant allow him to have a chance to get 2, no matter what! Number two, there is a ball hanging in the side and if you dont make it and you dont scratch, he cannot possibly get out on the next shot. Since it seems that you cannot shoot off of the ball in the side without making it or putting it into play then you are forced to shoot at the other ball. The only shot that seems reasonable is the Ghost's 3 rail kick. I refuse to put a ball into play that my oppo can win with on one shot.
There is a possibility that the 9 ball will go two rails and back to your oppo's pocket, but as long as the ball remains hanging in the side you are still alive. It is also possible that the cue ball will trickle behind the 9 and pocket the hanging ball. That aint so wonderful either, the shot is risky but you must take your turn, and the kick may be all you have. The kick is laying very good and the upside is, you might even make it and win.
What is important is to understand the eternal principle of trying never to do anything that will allow your oppo to win the game on one shot. That is on page on of the Onepocket bible.

Even if you take a scratch and DON'T leave a shot, there are two out of three balls in play and he can now win the game in one shot. With the ball hanging in the side, and just one other ball on the table, he always needs two shots or two mistakes to get out. This situation comes up regularly and seldom with the drastic nature of having to shoot at the 9 ball.
