Scott has a fair dominant position, meaning he has balls that he wants to protect. The 4 ball can be a liability, so it is expendable, and thus can be used, but mainly for a defensive shot, but there is a cross corner bank on the 4, very risky, can come with cost of leaving a cross corner bank, but I do not think the cb will leave a direct in shot.
If the 13 ball can be two railed and then bringing the cb back into the stack by the 3 & 12, that should do nicely.
Another shot is to bank the dark green ball straight up and down, it might go off the 8, but anyway you can get in a threatening position. Stroke down on the cb to drag to the opponent's side rail, having the stack protect your shot.
Thanks for the wwyd!
