Thinning the 2 puts the cb right in the corner. I didn't set up for the 2-9 because of the 4. While it is still makeable, it's tougher than it needs to be. All I had to do is get a shot on the 2, the 3 was another easy shot, and then the 4-9. I just misjudged the speed getting on the two. If the 2 to the 3 was tough, I would have tried that way.
I know you say a thin cut on the 2 puts the cue ball in the corner pocket but from your cue table layout I think it is worth the chance. With maybe a partial masse on the cue I think it would stay out and give you a chance at the 9. The 9 is a big ball so I would say fire at it. If you don't like that than the only other option I see is jacking up as high as you can and trying to draw the cue ball at the 9. Other than that swipe the balls and chalk one up for the ghost.
