I like`the shot the 15 ball then the ten ball . And the cue ball into the 11 and 6 ball.Even if you are froze. witch you wont be froze. Because you will be cutting the one ball. And you wont have a straight in shot. So you wont be jacket up. And from there you will have a good chance to run out.Even though the 6ball is dead I wouldn't play my pattern to play for the 6ball because you first must clear the 10ball then the 1ball to get on the 6ball combo..that's not easy considering where the 1ball is positioned. What I would do and how I would be thinking in this type of a situation would be to play for a good angle off the 10ball after pocketing the 15ball to go into the stack..split hitting the 11ball and 6ball and leave the 1ball as an insurance ball to complete my run. Putting all my thoughts into getting to the 6ball combination could be futile if I don't get a good shot with the 1ball to drop for the combo, and like I said that's not easy so don't be fooled with the appealing dead 6ball.
If you can diagram the pattern to drop for the 6ball I would like to see it. The position of the 1ball is lying awkwardly and trying to get to the 1ball to drop for the combo may be a mistake. Jmo.
And Like I keep saying shot the shot and you will see that you wont be froze. That is the correct way to play the shot. And if you cant get a good angle of the 15 ball to shoot the ten ball. Then I suggest you play position on the 9 ball. Then the 10 ball. Or you can go from the 9 ball to the one ball if you have the wrong angle.
And shoot the one then the 10 ball and your dead combination will still be there for you to shot. Or you can run 4 balls and lock your opponent back up, And I don.t think the 6 ball combination is dead. From the angle I am looking at. Ghost is the 6 ball dead?
