How should I have hit the CB differently to get the result I was after? Thrice across. Looking back now, I think I had a bit too much draw. The phone after the shot shows the english (not before the shot).
If your rails grip good enough, there is an option to bring the cb towards the centre of the table with inside English. Follow plus right-hand English in this particular position.
Another easier one is just playing shape for the long bank to the corner. Provided you were doing your homework in that department
