We can't see the exact angle on the 10ball. With this understanding it will be a guess what options are available, if any. Let's assume that there aren't any options playing off the 10ball, which will narrow the decision making process. We also should know that leaving the cue ball at the foot end of the table is extremely risky, especially for a ball running machine.
The only reasonable place to position the cue ball is at the top left of the table, and you must be precise with your cue ball placement, in this position. I believe it's time to take an intentional, but again, you must be precise with the placement of the cue ball. I would try to position the cue ball 1/2 diamond to the right of the top left corner pocket, forcing Shane to come off the 10ball. From this position Shane will be looking at an awkward angle on the 10ball that carries great distance, and there's no guarantee that he's going to do well with it.
I do understand that he will still be the favorite in this game, but what are your alternatives?
You must try to get by this inning without selling out, and then deal with the consequences next. Whatever they are.
