Doesn't look like there are any reasonable kicks to deal with the 4ball, the one rail kick is possible but very little margin for error. In this position you must move the 4ball or the 14ball. If you cant move the 4ball I would try to bank the 14ball to my side and remove it from the position it's in. The 14ball is a winning shot for my opponent and i'm not going to let it remain there if I can't move the 4ball. I'm going to bank the 14ball and swing the cue ball three cushions and try to double up the 4ball with the 8ball and leave distance. I'll take my chances from there.
I would shoot Franks shot if I felt that I could masse the ball and get in back of the 8ball, I see good things happening with that option.
